LRX and TTSX are great bullets...all Barnes Bullets are fantastic. I have tested their TSX bullets out of my 416 ruger it performed like a solid. Penetrated 14 2x10's. I hope you keep doing videos with these bullets. Love the 7mm too.

[@AlaskanBallistics]

The TSX won't expand at longer ranges and low velocities. But for up close on a brown bear... great bullet

[@NYPrepper]

@@AlaskanBallistics Yes for up close that's what I got it for

[@AlaskanBallistics]

I figured as much.

[@cjr4497]

In my 25 years of deer hunting Barnes bullets are the best killers I have ever used. There is no comparison. I started using them about 10 years ago due to having bullet failures with other lead core bullets.

[@AlaskanBallistics]

The Lrx and ttsx are great. The tsx is for short range only

[@medictg]

Agreed. Best bullet out there.

[@heyitsaluigi]

I plan on loading 150gr ttsx with it

[@cpprcrk1833]

Always great to see you post Chuck . Should be a winner at distance , hope that rig gives a lot of Caribou steak's & chops .

[@AlaskanBallistics]

And a few moose steaks too lol.

[@timallen6035]

Nice video. If you are getting around 3/4" groups consistently with the Reloader 22 load I'd say that's an excellent load. It sure tore up that pork shoulder.

[@AlaskanBallistics]

Agreed

[@NYPrepper]

Those loads had very low standard deviation, very nice.

[@AlaskanBallistics]

Thanks. I consider very low below 5 though

[@NYPrepper]

Have you tried finding accuracy node yet with a ladder test or similar test? If not you definitely should.

[@AlaskanBallistics]

no enlighten me

[@NYPrepper]

@@AlaskanBallistics make several loads going in 0.2 grain increments up to safe max or around the load with your desired velocity and fire one shot with load and see which loads group around the same location this will give you the accuracy window/node. For example if your loads with 60.2 60.4 and 60.6 grain of charge all have very similar POI that's the "accuracy window" . There are other methods. Of course you can also fire groups going in 0.2 grain increments to see which group the best, but the ladder test will save a lot of time and components to get you into the charge weights that will work the best with your barrel harmonics. Then you can experiment with loads in that range to see which one group the best.

[@NYPrepper]

There are some pitfalls with ladder testing though. Old school method of shooting groups at different charge weights is the best way to determine what is the most accurate charge.

[@Tex_I_Can]

You put a hurt on that pork shoulder. 3/4 moa is pretty good. Did you play with OAL to get it there?

[@AlaskanBallistics]

Yeah slightly shorter than the 4831 load

[@robpederson281]

I've shot a 140 ballistic tip through a factory Ruger for 40 years out to 800 yards imr 4831. Have shot elk to Prairie dogs with 1/2" moan out to 600 yds. These lighter bullets in a factory twist are exceptional performers with incredible terminal damage for quick results

[@AlaskanBallistics]

I generally run 145gr lrx

[@gabemcneil5221]

Always glad to see the bullet performance videos . I shoot with a few guys who have 7 mags. Most of em shoot 4831 short cut. Trim their brass, and play with the neck tension . I know powder is hard to find right now, and I have not found a 300 win mag that did not like RL 22. Down here in the south , on the days we shoot with the temps in the mid 90s, rl 22 almost always goes over pressure. It will probably do great in Alaska if you develop and shoot at approximately the same temperature. But down here, if you develop a load in fall or early spring near max load, that baby is gonna lock the bolt up in July and August ... I love the accuracy of RL 22 though in win mags.... try the 4831sc or even IMR 4350 . I have a buddy that shoots 140 LRAB in 7 mag with the imr 4350. Just a suggestion . Thanks for the vids.👍

[@AlaskanBallistics]

Thanks for the suggestions. I know about those July August heat days in Georgia

[@nathanmanley4203]

11 fps SD from 3100 plus fps average is probably better than most of the factory stuff but the 2 inch group is not terrible for most hunting ranges. That still within the vitals of an elk or moose out to 400

[@AlaskanBallistics]

Yeah i might be sitting 600 or slightly farther

[@christopherdick8675]

My new Sako 85 in 7mm rem mag is now my favorite rifle. 24" barrel SS, looks great, preffers the 140/150 grains really well. I use 140- partition and also accubonds..

[@AlaskanBallistics]

Those will work

[@paulscountry456]

When the M24 came out in 88 or so our armsroom had some chambered in 7 mag ,338 Lapa and 7.62 ×51,but the 7mm mag ones were transferred to the Belgian Military as NATO ally.I still think it is a super cartridge.

[@AlaskanBallistics]

It works well for sure

[@guardianminifarm8005]

Not bad. IMR 4831 isn't temperature insensitive. H4831 or Enduron 4955 are. But you may be correct about -5...lol...I have run 60.0 4831 in my 150s for a long time when I have a 7 mag. Very accurate. Looked good for a bullet that just shattered a big bone.

[@AlaskanBallistics]

I'll have to try them again as well with 4831

[@fotispapadopoulos6933]

Awesome. How about expansion at 1800 fps?

[@AlaskanBallistics]

I don't count on expansion below 2300 with any copper, but they say it's supposed to expand down to 1500... I'm eventually going to load up a minimum charge in 7mm-08 with an 18in barrel to see.

[@bartcornelius7717]

Hey Chuck. I just bought 4 boxes of Barnes 139gr LRX for my Tikka 7mm Rem Mag. How do you think they'll perform on Alabama whitetails from 75 yards out to 200 yards? I'm getting almost one hole groups at 100yds.

[@AlaskanBallistics]

I used the factory load 139gr on caribou at 459 yards. 1 shot in the heart and she went down. Make sure all boxes are the same lot number and chronograph them. But yes they'll be fine for anything in North America including deer.

[@danoneill2846]

[@terrycalvert7812]

My 7mag shoots 150 ttsx at 3238 average with an SD of 5.3 and reloader 25 and no pressure what so ever no case head expansion measured with a 1 inch ball micrometer a slower powder filling the case more will give a more consistent ignition and velocity’s

[@AlaskanBallistics]

Cool thanks for the info

[@Titan-iw7xv]

If you can get your hands on it try IMR 8133 powder, i shoot 160 noslers out of mine with a .268” 5 shot group at 100. Lights out!!! Good luck and thanks for the videos they’re great!

[@AlaskanBallistics]

You're welcome. I've not seen that powder at all. My rifle shoots .35" with the 120gr ttsx and imr 4831. With 145gr LRX and rl22 i get .7" I'll definitely try it if I can find the ammo.

[@coddizzle]

Be interesting to see the expansion test and a couple hundred yards. I'm working up a 139gr load and plan to shoot into dirt bags at a few hundred yards just for curiosity

[@bustabass9025]

Ever since I discovered the 28 Nosler a few years back, my 7mag has pretty much been on the inactive list. I always got great accuracy with it though, using 140 grain Nosler BTs and Reloader 19. But this 28 Nosler with 168 grain Nosler AccuBond LR bullets and burning Retumbo powder, is strictly lights out when it comes to taking anything in North America on four legs. It shoots flatter than an opened can of beer that sat overnight on the camp table, and hits harder than a Joe Frasier left hook.

I bet. If you live in AK let's meet up and do a chrono video on it

[@AlaskanBallistics]

Got to get some of those bullets first

[@frankbrowning328]

Impressive video! I like the stock on your Rem 700. Who makes that? Looks very comfortable. RL22 seems to be a go to powder for the 7mm Mag. Accurate and high energy. LRX performance at 60 yds WOW!! would like to see how it works at say 200 -300 yards. At longer range will the petals remain? If the petals shear off as they did at 60 yds will the bullet still mushroom as it did at 60 yards? Love those pork explosion videos!!!

[@AlaskanBallistics]

That's a magpul stock. Check out my video on it. I've shot the 139gr at a caribou at 459yrds and never found the bullet

With all the velocity measuring you do, invest in a Labrador or at least a magneto spreed. Those cheap chronographs aren’t really accurate and I wouldn’t use trust those to build up loads.

Lab radar says in owner's manual that it won't below 20°F I don't like attaching anything to my barrel. What else would you suggest?

[@eddielombera5862]

@@AlaskanBallistics I enjoy your channel, and as big as it is it needs those 2. Labradar for when you’re shooting at those temperature above 20F and the magneto when it’s not. These cheap chronographs can be very sensitive and they WILL give you false info and you might be blaming your powder charge when in fact it can just be your equipment. I don’t like strapping anything on to my barrels either but I’m not doing groups with the magneto, just to get accurate velocity measurements. Just my 2 cents, I hope you can take this as constructive criticism.

Are you not crimping?even a light taper crimp might help speed a little. Powder charge for r 22 is low. Number 12 Speer with 145 grain Speer says 69 grains is max. Number 8 Nosler, 67.5 with 140. Their bullets, not all copper. Could be overall longer length with the Barnes bullet. Will the chamber let you load a little long? Or does magazine dictate overall cartridge length?
