Case doesn't shoot well

[mgunderson]

So it sounds like not all brass shoot in every rifle.

The reason I ask the question, I have Lapua .308 on its 12th firing in a HOWA chamber. I have tried 3 different powders, 3 different and different bullets/weights/manufacturers and different primers, I can't get the Lapua to give me consistent results.

Every time, I anneal, full size with 2-3 thou shoulder bump.

Thank you all for replies.

If you have a 308 that shoots some brass well but doesn't shoot Lapua.... something else is off. Speed or neck tension.

Federal, Lake city, almost anything else can be off at times. Never seen it with Lapua. Lr or small rifle? What are inconsistent results and what range?

Why are you bumping the shoulders?
Is the round chambering with difficulty?
The only time I bump a shoulder is if a cartridge takes effort to chamber meaning closing the bolt is either too stiff or not at all.
If I have this problem 1st I try f/l resizing again but allowing the case to sit in the die for 5 seconds or so. Most times that solves the problem. I try to work the brass as little as possible. Some, like my 222 have never had the shoulders bump. But my experience has shown me that cartridge to be very easy on brass.

I can not close a disassembled bolt my Lapua fired case. So I bumped back to a point so the disassembled bolt closes.

Perfect reason

Thank God that I can't possibly shoot nowhere near well enough to have the slightest idea if my gun likes a certain brand of brass. But it does give me an opportunity to blame something other than myself for missing that woodchuck.

Each brand seems to have slight variations in capacity vs other brands. My experience with Winchester cases being thinner with more capacity. How much variations would you get by changing your load by 2-3 grains.

So why do you think it is the case?

 

[Steve Donlon]

It could be over annealed. Neck tension not consistent

Similar to a bullet that may not shoot well in a barrel. Is it possible that a certain case doesn't shoot well in a rifle?

Depends on your criteria of not shooting well.

If it is shooting 3's and with other brass it shoots 1's, then yeah.

 

[Chiquita]

So why do you think it is the case?

It is not consistent SD, ES. With Starline I can get single SD , mid teens ES and groups sub ¾.

FWIW, I anneal with AMP.

Does this satisfy your accuracy criteria ?

OH! Maybe it's under annealed with Lapua brass

Setting aside general quality of the brass and manufacturing consistency...

Brand to brand, lot to lot, I think neck thickness and metallurgy (spring back) affects how well brass performs in a particular rifle/chamber.

One brands neck thickness may fit a chamber better than others and allow for a consistent release of the bullet.

Some shooters will spec their chamber reamer for optimal clearance with their chosen brass (Alpha, Lapua, Norma, etc.), then have sizing dies made also. This is likely the best way to control tolerance.

Tight neck chambers, neck turning and bushing dies all come to mind... but that's a serious rabbit hole.

Well he marked this with with a "like" so I guess he is satisfied with how it is shooting with Starline brass.
So, end of thread. If he is happy with his current results, no need to change brass or anything else.

I have a Utica, NY made Savage 99 EG in .250-3000 that doesn't like Remington brass. The same handload in '70's -'90's production Winchester brass will shoot a 4 shot group into an inch but switch to Remington brass and groups open to 2.5". I have no idea why.

I'm fairly new to reloading.

I switched from Nosler brass to Lapua brass with a sub-MOA .223 load, and couldn't get the same performance with Lapua. Per a friend's suggestion, I reduced a grain or two with the Lapua brass, and it worked! His reasoning was, the Lapua brass is heavier.

A different rifle, I switched from Hornady brass to Lapua brass with a .243 load, and the groups tightened up from 1/2 MOA to 1/4 MOA (without any other changes). You figure it out.

I have found some good loads in 204 Ruger,.223, 6 Creed,6.5/284, change the cases and the Groups Open Up ,have 2 6-BRA's,with Lapua & Peterson brass it's a toss up. Believe I'm not shooting enough. lol

Could be internal volume difference - tried comparing Hornady with Lapua using water ?
