I am in the process of loading up the Chinchaga 375 cal bullets in several of my cartridges .... first will be velocity/pressure tests and once I find the max will start testing for accuracy and expansion on water jugs at 50 yards to see how they expand/stay together, then will load low velocity with key powders and try to get 500-800 yards vel expansion

Looking forward to your results in the Mercenary and Snipetac.
I already swage a similar 435gr for my Mercenary project.
I'm thinking of squeezing the Bullet down to the 30 caliber tip for a 400gr ish Bullet for my buddy's Snipetac.

So far, with limited experience, the 375 grain Chinchagas are shooting extremely well from my .375 Snipetac. Latest outing shot under 1/3 moa @ 200 yards and so stretched it out to 800 and put two less than 1.75", then had a buddy do almost as good at 2.5". More testing is in order at longer ranges to confirm.
155 grains of RL50 @ 3125fps.

An update on the 375 grainers:
I shot a whitetail buck @ 430 yards yesterday evening. He was facing me slight quarter to my right. Almost got it on film, he walked out of frame when I was getting behind the rifle.
Needless to say he dropped in his tracks, so hard that he bounced. I guess that's what should be expected with a 375 grain "soft" bullet & 2600fps/5650fpe on a hard impact. It was absolute carnage! Tore a hole about 5-6"" wide and 12-15" deep, almost took the shoulder completely off. This is what folks would expect a chambering of this size to do. This is an example of the ol' "You will blow a deer in half!" type of speech comes from. I will not be shooting deer but behind the shoulder with these unless the range is really long. When skinning I found a severely mangled piece of the bullet about 150 grains worth. Can't find it, it was dark and I think my dog ate it.
Cant seem to imbed a video. Not gonna post pictures as it may pee some folks off.

I've still been waiting for the 435 bc. I had kirby set mine up with the 375 and 400gr lazer from cutting edge. Hopefully the throats won't be to long to run these later as a repeater as both the lasers turned mine into a single shot.
I would like to hear more about this, any updates?
Also like to hear what velocity anyone is getting with the 435 grain projectiles from any Cheytac Improved chambering.

I to would love to know more wonder if I screwed myself from using these after clambering my AM for the 400gr cutting edge. I should have kirby cut me a second barrel for standard cup core just as a backup or a switch to later.
It's been a long time for the bc from applied on the .375gr. I heard the bc was not very good from several sources that have tried them out to distance. I'm hoping they are wrong cause I'd love to launch the big ones.

snox,
From those that said the 435 grainers BC wasn't very good, what are the numbers they are using. I haven't seen or heard anything, been waiting on Applied Ballistics to put some numbers out as well. The furthest I've shot the 375 grain version was 1337 yards and used .8 G1. Looking at the 435 & 375 next to each other my guess is the BC is over .86 G1. Now this isn't great when compared to the CE bullets in this weight class, but still not bad. What needs to happen is for Berger to put out a high BC VLD (not lathed turned).
I can understand your concerns about having to seat them out so far as to not use it as a repeater, and maybe wanting another barrel for the long really high BC projectiles. Mine was chambered (and twist rate) the opposite, more along the lines of the 350 Matchkings and other cup-n-core bullets. I also have a longer 36"/1-8" twist barrel I want to chamber for the longer bullets, thought about a larger chambering as well. I don't know if my rifle can push the 435's fast enough to have as good of down range performance as the 375's.

I was never given specific bc which is why I took it with a grain of salt. But both parties said the lazer would far outdo them. I got a 34" 9 twist for mine so I should be good for any of them. I may have a second barrel done of it doesn't take that long as kirby is sooo far behind right now. I to am hoping berger comes out with one but they have not even talked about it. I would think we would see an eld-m before berger does one. Whoever does one first should make lots of money as more and more people are moving to .375 for real long ranges.
I agree, thought there was mention of a .375 Amax a few years back. If one makes a good VLD projectile I think the other will soon follow suit, they will definitely sell. I know I would be all over them. It would be a good middle ground between what we have now, better BC than the Chinchagas and better terminal performance than the CE= perfect!

That's what I was thinking and hoping for also.

So the cutting edge lazer are back ordered putting my load work for my AM on hold again. Now back to wondering if I should try the 376gr and 435gr chinchagas. Wish I could get a bc for them.
