6BR for Long PD --What Bullet?

[urbanrifleman]

87 VMax shot from a retired 1000 yard BR barrel. Used H380 just because I had an 8 pounder. Slayed a few PDs at 800-900 with this setup.

I have no doubt that 18 year old 87 vmax shot well.

Just the new ones are the problem.

87 VMAX and 29.7 grains Varget , Norma 6 BR brass and 450 primer , .015 out from hard jam shoots amazing in my 8 twist barrel
That brass prefers not being pushed to a higher accuracy node

Are these 2022 bullets or old stock?

I was on a pdog trip last month where the 87vmax's out of a 6br blew pdogs up at 660 yards. They were new ones. The ones I bought from you last year, I put on paper at 100 and 300 yards. Threw the load together off of Quickload. 5/8 moa at 300. I know I can make it better.

I've bought more from BCR 3 months ago while I was there.

Funny you say that. Was preparing to load some 87’s the other day and noticed a difference with my measurements. I always kept an 87 in the case with my OAL tool but it is an older one. Used it for my measurements but was loading new ones. Measured the first one I seated and saw the difference. Lesson learned I guess.
So I measured the one that is probably 8-9yrs old and also one out of a new box.

Old is top pic/new is bottom pic

I always check every new lot of bullets I buy before loading. That way if some development is needed I know before hand.

I'm curious to see your findings. I would LOVE to figure these out.

One thing I noticed is that you need a REALLY long freebore to keep them out of the donut.

I'm using a bushing die and only size part of the neck, shouldn't this keep any donut clear of the projectile?

Yes that is good way to keep the donut from making a difference

I just measured the 2 different lots of 87vmax's that I have with my comparator, 0.006" difference between the 2.

Don't overlook the 80gr sierra blitz. They work well for me at long range, and come all from together!

shot the 87 vmax today out of my Savage/Shilen 6br(8T). Varget in .2 increments from 30.3 to 30.9, loaded .020” off. Shot (2) 5 shot groups of each.
Had slight pressure at 30.9 and groups opened some to about .700, but 30.5 shot in the .3’s.
I will take that as a win for today since I was fighting a wobbly wooden bench and haven’t had any trigger time recently due to rt shoulder surgery. That has me believing there is more in the tank with some tweaks, and if I can do better, which is usually the case…

Well crap!!!

I'll guess I'll try another batch. I have a brand new 6bra 160 FB and I'll make some up.

87 vmax sticks into the case almost as far as a Berger 108.

160 fb at touch. If it likes to shoot jump it will be even further in the neck, then I'd say 140 MINIMUM for this bullet in 6br.
