Lapua makes top-shelf brass, and their 6.5 Creedmoor offerings are no exception. If you've used this brass, you're probably aware that it's available only with small primer pockets. Well, that used to be true, but recently Lapua released large primer pocket 6.5 Creedmoor brass, and it's given me stellar results this last year with long-term testing. In this video, I'll compare both of these brass SKUs- taking a data-driven approach!

Hi, I've been reloading the Lapua small primer pocket for years and I think I must have over 30 reloads and still going. I don't keep a record of the actual shots but I do keep the sleeves from the primer packets and I have used over 3500 primers.. and still going. Great brass.

Great info. I have A Bergara B14 Rifle that stripped the threads on the bolt shroud. Bergara sent me the parts at no cost to me but blamed it on the small primerLapua brass. My question “how does that matter”. Bergara s answer. Hornady designed it for lg primers. Interesting note. The shroud that stripped was forged and the new shroud was machined and fit better. Also 21 st century sells primer plugs so you don’t have to waste a primer for the case volume test. Great stuff as always. Thanks Gavin

I can offer some insight into that based on 1000 yard bench rest competitors at our local range. These guys shoot a lot of different calibers but they all seem to be of the opinion that they will choose the small primer cases every time whenever they have the option based solely on better accuracy performance from the small primer cases. They also have tested drilling out the flash holes to the same dimensions as the large primer holes for ease of decapping without having to buy special dies with the smaller pins and found that it greatly affected accuracy in a negative way. I personally have not compared the differences, based only on others experiences.

Small primer pocket brass is stronger, better for hot loads. That's also why it lasts longer. Remember that when the first 6.5CM brass cases were produced with large primer pockets, the 6.5x47 was a bit more powerfull than the Creedmoor until they decided to change to small primers.

@@benwright3314 Hi, for the pressure that's right. Lapua produces also special .308W cases with small primers pockets (.308 Palma) for the same reason. Palma competitors use it because they need the highest velocities possible on the .308 winchester caliber. The 6.5 creedmor is a high performance cartridge because it has a better case design, but also because of the higher max pressures, so it needs strong brass cases to give its full potential. If you have ignition problems with some powders there also the solution to use small magnum primers.

If temps are below 40-45 degrees F, then I either use SRM primers or LR primers. Late Fall to Early Spring, I usually use my LR 6.5 ammo. The velocity ES does increase with my LR ammo, but velocity average is fairly consistent. I’m also working on a project to see if I can get my ES down in winter by using a different powder.

Hi Gavin. Emil Praslick from Capstone here. One of the major considerations we had when we were developing 6.5 LRP cases was the issue of some semiautomatic platforms piercing small rifle primers due to dimensions of firing pins and the firing pin hole in the face of the bolt. Also, the US government's specification for 6.5 Creedmoor requires a large rifle primer. Great content!

I'm getting a bit confused by your comparison of the case lengths. The caliper you're using has a rated accuracy of 0.001" and you're using a sample size of 10. How would this lead to a significant result, from which you can draw the conclusion that the large primer variant is better? The standard deviation is below the accuracy of the calipers and the difference in extreme spread is within the accuracy. So, based on that and the avg, I'd say that the tolerances for the two variants is the same.

Be sure to use a small decapping pin with Lapua 6.5 Creedmore brass. I ruined most of the flash holes in the 100 I resized using my Hornady die. That die is meant for LRP. I purchased the SRP brass when that was all I could find at time I started this build and didn't bother to check the first case I worked. Hornady will send you the small pin for that die. Good luck.

Great video Gavin! Another reason for SRP brass is the amount of pressure. If you are loading toward the higher end of the spectrum, the SRP brass has more material at the case head and will hold a little more pressure before seeing pressure signs. Keep the videos coming. You do a great job.

I wonder if these consistency measurements are less so down to Lapua using different dimensions and more so down to the fact that they're Newer and thus the tools Lapua uses to produce them are less worn. In which case a couple years down the line, when Lapua inevitable refurbishes/replaces the SRP tools when they're worn out of spec that they will suddenly be more consistent than the LRP tools since those would have worn just as much as the SRP cases you measured in this video

And if you cannot shoot this all means nothing. The greatest improvement to accuracy is not components but practice. Some time ago a friend related a story about a national shooting champ on the range his friend who was was unable to get get a group with cheap factory bought ammo, So he approached the champ to shoot three shots as he believed that this would prove his point, that the ammo was useless. They champ sat down and produced a small clover leaf. That was the day he realised that reloading is more about marketing and selling you components and kit you don't need in the belief that it is not YOU but all the other stuff that makes you inaccurate. It is primarily YOU. Weighing bullets, sorting cases by capacity, buying Lapua brass, priming with BR2 primer have never helped my groups one iota, but practice does.

I disagree with one factor in your large vs small primer analysis. That factor is powder choice. Some powders ignite more easily than others. For example, when I spoke with the powder guys about 6.5 Staball (ball powder) for use in the 6.5 CM they specifically recommended large primers. Some people have apparently experienced somewhat inconsistent ignition when used in conjunction with small primers. Although this powder was designed to be temperature stable, I would not be surprised if testing were to disclose that low ambient temperature had an effect on ignition. Years ago Benchrest community testing concluded that the maximum powder column height that a small primer would consistently ignite to their satisfaction was about 1.75 inches. You may also recall the thin wall small primer “Palma” .308 Win brass. It was well known to be a warm weather combination. I note that you have a review of 6.5 Staball which I look forward to watching.

No error bars quoted? GT's assuming he makes no mistakes in using the kit (clearly not true) and the kit has perfect repeatability! You have to doubt validity of stats to the quoted levels of accuracy.

Hey Gavin. Thanks for sharing your knowledge. If you have not compared the Starling brass to the Lapua brass. In both Lrp and srp. I would like to see that. Including velocites, deviations, and powders. I compared to you and a novice reloader. Though I have been reloading about 20 years. The only competitive shooting I do is against myself. So primarily I use my reloads for hunting. My belief is this though, wether competitive long range shooting or hunting. It is still about consistency ,shot placement and accuracy. Thank you again. John.

Time for your silly question of the day !! If going with small primer pockets, would using small magnum primers help with possible ignition problems ??? Thx. for all the great info, love the channel !!

I am surprised the AMP press doesn't use a spherical contact on the press head, rather than the (apparently) flat contact used. You would need a hard surface on the seating stem cap and it looks like it may be aluminum (but could be SS). The spherical contact assures uniaxial concentric force applied to the punch. I notice the "bullet assembly" almost always "rocked" when the force punch is retracted.

I was getting short of LR Match primers and wanted to see if the SR Brass would work, since I have some SR Match primers left. Good Thanks. The hunting aspect is a good point, but folks have been using the 30-30 for many decades with the SR primer and I have yet to see any griping about the primers. I think the SR issue in the cold is a case capacity issue with mag cartridges and using harder to ignite ball powders.

Regardless of the resolution of the digital display, you can’t use a caliper to accurately or repeatably measure to half a thou. It’s generally accepted that you don’t use a caliper for anything tighter than +/-.002”. Even the best calibration certificate I’ve seen direct from Mitutoyo had an error of .0015”.

Use both. Bolt and gas guns in 6.5 CM. Since we tend to load to max or above for velocity and accuracy, found large primer blows out pocket much sooner. So, expensive brass, small primer lasts longer. Intuitive read is that large primer performs a little, though very little better, but not measured as you would. If we had a choice I’d use small rifle magnum primers consistently. Today that’s just an unrealistic luxury. Agree, Lapua brass is excellent. Have similar results with Nosler brass. Both very good. Your analysis is very helpful.

Hey Gavin, love your work. I would really love for you to do the testing on Peterson brass 6.5 Creedmoor. I have found that Lapua brass is king but when compaired to Peterson, I have found That Peterson brass is very consistant also. And is A bit more price friendly than Lapua. Also I am Curious about Powder ignition, And how it relates to deviation in uniform pressure, Provided by large Vs small primers

Thanks for all the work that went into this study, Gavin. One comment of comparing SD's between groups in your measurement: Since SD is a square root, it's not correct to compare by looking at the difference (i.e. subraction) of one to the other. Need to convert each back to the variance first. Hope you keep up and share all your efforts in helping us understand reloading and components!

Giant stretch and workout for my physics knowledge. However, after turning off the tv I was able to follow your tests and logic (the math). With the shortage of all reloading components including presses, I’ll file this video away for the future. Thank you - future reloader. Excellent physics job- thanks

I just purchased the Lapua small primer 6.5 creed. I have both, large from Hornady. I have not yest tested my loads, but the biggest advantage for both is primer availability. I happen to have both but some may not. Other than that, this was a great video as I was wondering all the thigs you presented. I now know I can have my cake and eat it too! Thanks.

Will their be velocity differences between the two? Will the SRP exhibit a velocity bump or the LRP? Will one be more consistent than the other over the course of a PRS match.
