Yup... you are reading it right... was real twizzler to me... talked to the Walther's rep at the NRA show back at that time and he just shrugged his shoulders... I was on my own...

Hans... Thanks for your comment. I did check out your video and looks like you doing some nice work. What I glean from your work is you're trying to make a superior long-range 22 LR. With the current offerings from the Lapua/SK/Eley that's gonna to be a tall order and I wish you the best. Check out the offerings of the reloading kit for 22 LR from Cutting Edge Bullets. They have a table of load data they did with different powders, which based on my work, is going to be the biggest challenge. Also, I did a video on 22 LR relative burn rates which you might find useful. ...Don

Norm.... I didn't do any concentricity testing. The profiling is done in a die which contacts the drive bands and there wasn't squishing of the nose of the bullet to get near these drive bands.

Thanks for your comment… Option A, contact your supplier or LEE and swap it out under warranty… Option B, work with somebody else that has one and do some same sample testing… Option C, obtain some high purity lead, usually 99.995% is available, test and if that measures between 4.5 and 5 BHN you're probably good to go!

@@PounderLabs thanks Don

Dino... Sorry about the audio. Got everything set up and found out my lapel mic crapped out so I needed to use the shotgun and didn't get levels set right. I bumped the volume best I can but that's about it. I did the video couple weeks back, but I think the PhilNealer has been around for 20+ year? I've never seen a video on it or even any description, so I thought since I had access to one thought my viewers might like to see something interesting. Cheers, Don

I wouldn't speak for everyone doing rimfire but, because it's a relatively low-cost platform they like trying new things and, of course, the pursuit of ultimate performance with the mystical combination of platform and ammo.We have three CZ457s all put together for a specific purposes. We wanted the Lothar Walther because of the profile and longer than the traditional 16" threaded so we could experiment with muzzle device like tuners and bloop tubes. The second has an IBI 22" with their "Olympic Contour" which has a Shnuble nose for studying barrel harmonics. The last has the stock factory 24.5" threaded that came on the first Precision Varmint Trainer with the Manner stock. Performance? From 50 out to 200+ yards, on any given day, I wouldn't want to live on the difference between any of these. ...Don

Hi Jimmy..... You don't provide much information here so, I'll assume you are using 1911 full frame, this is what my video deals with, you are using standard factory loads and the spring you have now isn't working for you anymore. Go to the Wolff website and follow their recommendation for the caliber you are using. If you are reloading, still start there and go up of down a little to dial in your best performance. Remember, these spring fatigue over time with use so, you should replace as needed. ...Don

billj... I think what you're suggesting in theory should work. Couple things to keep in mind. To oversize the 38 Special brass, i.e. significant increase the negative interference, may require custom dies. And since jacketed bullets are usually .357" you can probably muscle them in, but you probably will end up with a pretty significant Coke bottle affect. Lead bullets, and those with coatings like Hi-Tek, are usually sized to .358" and may be damaged in seating in the oversized brass. Since we normally don't anneal straight wall cases, working the brass this much may limit your number of reloads, which may or may not be an issue. ...Don

My experience bears this out, Don, particularly with the softer lead used in swaged bullets. I used bullets cast from softer alloys. Bullet bases become deformed (singnificantly undersized) during the seating process. They don't shoot as well, and leading, even with very light loads, is apparent. I believe your canneluring method here is the appropriate solution to building consistent pressure without deforming bullets in a deleterious way.

Hi Dino… As always, thank you for your viewership and thoughtful questions. Unfortunately, in this case this unit is on loan from the owner, and we need to return it directly as I believe he plans to sell it. Hopefully the buyer will invest in getting some performance correlations. Cheers… Don

I agree. The manufacturer warranty should not be void because of where their product is sold. This is not acceptable today. Shows they do not stand by their product nor care about their products quality. I will definitely be boycotting their products and spreading the word.

I agree. I was thinking of getting one of their barrels too and am definitely going to double think this. I bought a Shaw barrel from OPlanet and had head space problems from a drop in barrel. Shaw had me send it in and they head spaced it for free. I paid shipping. The never even asked where I got the barrel. They just did it. I think Don made the choice for the better even though he had none. Mr. Pendergraft got some valuable advertising.

Polygonal huh?? I wondered about, with regards to why more .22lr rifle Mfg.'s didn't do that and hammer forge barrels, which is why I love my CZ. I'm a HK pistol fanboy mostly because of the polygonal rifling they use and how all my pistols seem to not care what they eat as a steady diet, as everything shoots well in them from factory ammo to my handloads.

Siyu... Thank you for your viewership and comment. The problem we had with the LW barrel IS NOT common and giving Walther's reputation and quality we were surprised we came across this. All 22 LR bullet profiles and rifle chambers, as we discussed in this video, have small differences. So, this is one of the reasons, once you do your build, you want to try different ammunition to see what works best. For match quality ammo whatever bullet profiles you consider, generally, small amount of engraving on the bullet is desired so it doesn't "jump" into the rifling. This is shown to give the best results. ....Don

Roberto... Thank you for your comment and your viewership. I hope I understood and extended your excellent research a little bit! I hope all my viewers look up your other papers… Don

Thanks for your viewership and your question. I can't say to a certainty that LW doesn't fabricate their barrels to a specific manufacturer, but I tend to think they don't. We've seen different chambers favor different bullet profiles for 22 LRs so our best recommendation is to try a couple of different manufacturer's types to find the best chamber fitment and look at various lots to get the best standard deviations for velocities and hits on targets.

Gary… Thank you for your question. Yes, Tuner work is in plan. That was the original idea behind getting the 20-inch LW barrel. We are finishing two videos about the fundamentals and practical methods for using Rimfire Tuners. We’ll be focusing first on the CZ 457 with the 24-inch barrel and Harrell’s Spiral Hole Radial Tuner/Brake. Should have these posted before the end of April. Cheers, Don.

I’ll anxiously await your results. I tried the Harrell’s clamp on aluminum tuner and it did make a difference on point of impact for the different settings but at the end of the test it never improved over the bare barrel. This leads me to believe that tuners are more effective on long, small diameter barrels.

Gary… Thank you for your viewership and question. The question of barrel length for 22 LR is a common topic. From an internal ballistics point of view, for the 22 LR in a rifle the maximum velocity for target (subsonic ammo) is probably 16 to 18 inches. Our take is the best barrel length depends on what you are doing. The high-end ammo providers, e.g., Eley, Lapua/SK, RWS all quote rifle ballistic data in 26-inch barrels because of their focus on International/Olympics type competitions that need the long barrels for open sight radius improvement and balance, particularly in offhand. You’ll notice, many of these rifles even have sight extenders on these long barrels, common called bloop tubes, to increase the site radius even further. Back in the days of the Winchester 52D and Remington 40X for 3-position/prone we indeed had 26 or 28-inch barrels. In other disciplines, like Rimfire PRS and NRL22, running around with these extremely long barrels is impractical and shorter barrels are preferred, as higher velocities maybe more important than absolute precision. Also, if you’re using muzzle devices like tuners, brakes, suppressors, etc. that all add length you end up seeing a trend toward shorter barrels like the 16.5-inch. And in other disciplines, e.g., precision rimfire, rimfire benchrest, etc. all follow their own guidelines based on desired performance and trade-offs. For the work we do, the sweet spot is around 20-inch, short enough to give us our velocities, long enough to not interfere with our tuners and brakes. Interesting, when CZ introduced the MTR, which has been getting great results even in the 16.5-inch barrel, we saw a trend from them to push many configurations to 16.5-inch. But now we see their 2022 generation is trending back to 20-inch. Hope this helps, Don.

@@PounderLabs Very informative, thank you .

Hi Gary, I had similar questions. This is some additional information that affect barrel length selection in addition to what Mr. Lutter stated. There isn't much velocity to be gained with most standard velocity 22lr after 16. They also do not loose much going a little longer. F.J.Feddersen says on their web site, of their precision 22lr barrels, that their 16" bull has the best harmonics for standard velocity. Their 18" has better harmonics for high velocity loads. It follows a 20" could have better harmonics for hyper velocity loads. Other manufacturers barrels may have favorable harmonics at other longer lengths by using other profiles. Note that longer barrels are quieter with standard velocity 22lr, as the gas pressure falls off. This could be a big feature before foam ear plugs and suppressors. The pressure of the gas escaping and blowing past the bullet as it leaves the barrel is another factor for accuracy. One of the reasons a properly crowned barrel is important. It follows that a longer barrel has lower pressure gas blowing past the bullet as the cork is popped, potentially contributing to precision. Longer match barrels may be able to take advantage of less bullet disturbance at the critical moment the bullet leaves the barrel and also choose a profile with harmonics tuned to that length, as well as the longer sight radius pointed out by Mr. Lutter.

Roh-Roh... Joe.... Thank you for your viewership and thoughtful comments. First, you are correct Lothar is misspelled several times as Lother. My last name is Lutter so I might have a blind spot for how this word is spelled :-( Second, I believe your point is valid on Carl Walter of Germany makes the high-end Olympics guns and, as I understand it, Lothar Walther is their American operation focusing on barrels like what we're using in this video. I have personally owned Anschutz, Walther, and FWB rifles/air rifles from Germany and I will attest to their quality and precision. Actually, that's why I didn't hesitate too long to invest in LW because of the rich history of German gun manufacturing. Lothar Walther talks this up on their website so imagine my surprise when I got what I got when I reached out for help. Much of this video is about identify and fixing things that affect rimfire rifle performance, but we wanted to give our viewers the background understanding why we're doing this. And in their defense, we're very pleased with the performance of the LW barrel... I just think we could've gotten this sorted out quicker with a little help from them. I edited both the video title and the description and also made the changes in the PowerPoint. But if I upload a new video, we lose all of these comments and I think it is more valuable that we discussed this here instead of starting all over the new video upload. Cheers, Don

@@PounderLabs Hi Don, I've never seen an actual Lothar Walther barrel in person so I'm just after 'Googling' images of Lothar Walther barrels and compared the branding stamp on those compared to the branding stamp on a KK500 stainless steel barrel. They are both done with the same process, either laser engraved or acid etched (I can't tell) - not letter stamped, so that's one shared similarity. The "Lothar Walther" branding and calibre marks are different and much larger, the "Carl Walther" barrel has the flag logo with "Walther" written on it. So at the end of all that I still couldn't say for definite whether they work with one another or not. Glad your barrel turned out right in the end and good luck with it for future use and competitions.

Hi Brian… Thanks for your question. I haven't used these dies but offer my best guess based on experience and what I have check. This die set is for loading the 38 Special wadcutter (thus the WC) loads we are discussing in this video. There would be a full-length sizing die, a seating die design with a flat seating stem to match up with the flat meplat of the wadcutter (the stem might even seat the bullet slightly under the mouth of the case) and a roll crimp die designed for this particular application. Hope this helps, thanks for your support… Don

Al... Thank you for your question. Sorry for any confusion in the video but you are correct the process we use is: 1- Rolled the cannelure onto the bullet by itself first..the UCTII doesn't create any ridge on the bullet to interfere with seating, 2- Seat the bullet as normal, usually a small flare on the case mouth will help prevent any shaving of the bullet as it is seated, 3- We do a roll crimp, as a separate process step, to remove the flare and provide a nice rolled edge for the flush seated bullet, 4- Then we roll the case cannelure(s) on the loaded round lined it up with the cannelure(s) or we added to the bullet… locking the whole thing in. Thank you for your viewership and support… Don

@@PounderLabs Thanks Don, this is what I was hoping you would say, males perfect sense. Keep creating great and informative videos!
