Yet another question( Neck Sizing)

Please excuse if this is a dumb question. I have a 22-250 and usually fl resize..just enough to bump the shoulder back to get the round to chamber. I tried an RCBS Neck size die and after sizing the case...Can not get it to chamber in the rifle. RCBS says I'm ShiP out of luck and can never neck size only. Seems odd to me!

Rem 700 VLS 22-250. Will I have better luck with a Redding die maybe? I can't believe I'm only gonna be able to FL size my brass.

Re: Yet another question( Neck Sizing)

Lablover,

It depends on how hard you run your loads. If your driving them hard, you will more then likely need to at leat partially full length size your case everytime.

You should be able to get your cases back in the chamber though, they may be quite tight but they should rechamber.

Take a just fired case and see if it will chamber in your rifle. If it will not your running your pressure to high. The bolt should close on a fired case, may be tight but it should close.

Sounds like you got ahold of a lazy SOB at RCBS. What is the point of the NS die if you still need to full length size you case afterword. The person you talked to either is not educated enough to help you with your problem or is flat out lazy.

One thing to look at is if the fired case WILL chamber in your rifle but a neck sized case WILL NOT chamber, more then likely you are adjusting the die down to far and disrupting the neck of the case and puching it out of dimension from the chamber.

When I neck size, I like to size only about 2/3 or the neck.

One disadvantage the standard neck sizing dies have is that the case is not supported when the neck is being sized. If the brass is soft and it takes pretty good pressure to size the neck, the neck/shoulder junction will become bulged from the lack of support.

The best neck sizing die on the market is the Redding Comp Bushing Neck sizer. It has the sliding sleeve to fully support the body of the brass during the sizing operation, preventing any inadvertant changes in the shoulder and body dimensions.

Neck run outs are usually in the 1's with the Redding as well.

Good Shooting!!!!

Re: Yet another question( Neck Sizing)

lablover ,
Check overall case length as well . .22/250's stretch cases rapidly with warm loads .
Common with the Rem. 700 in .22/250 to find cases extract easily with hot loads but won't rechamber without full length sizing . May have to back off your loads until you can get 3 or 4 reloads before full length sizing is required . You'll be trimming cases very regularly otherwise and after 3 trimmings they're junk .
After having owned a Rem. 700 .22/250 and a Sako .220 swift I found that the best way to get .220 Swift velocities is with a .220 Swift .

Re: Yet another question( Neck Sizing)

Aussie,

Actually, the best way to get Swift performance is with a 22-250 AI.

Here is why and its advantages over the Swift and the standard 22-250.

-nearly zero case stretching even with full tilt loads when chambered correctly.

-Every bit the velocity of the best 220 load. In fact in same length barrels, the 22-250 AI will actually have a slight velocity edge.

-Ability to fire factory 22-250 ammo and in the rifles I have chambered for customers, will get 1/2 moa groups with these loads on average.

-More efficent case design then the Swift, feed better(no damn rim), better powder ignition characteristics and better quality brass.

SO in my opinion, I love the performance of the Swift, but it is far better out of a 22-250 AI then the swift itself.

For real serious 22 caliber rounds, I prefer the 22-6mm AI with a 55 gr pill loaded to 4200 fps out of a 26" barrel. This is easy to do with 56.0 gr or RL-22 and pressure will run about what a 22-250 will with a 50 gr pill at 3800 fps.

Just one smiths opinion.

Good Shooting!!!

Re: Yet another question( Neck Sizing)

The thing is some of these loads are starting loads in the sierra manual. It is funny however..They seem to chamer fine but there is a kind of bump...or nick right before I close the bolt (on a fired case) as well as when I open the bolt (on a fired case) opens fine right up to the last part of the bolt handle completing it's travel before the bolt comes back.
Weird

I'll investigate length in the morning...Part of me thinks it's that.


Whats the best way to set up a neck die for sizing...

Re: Yet another question( Neck Sizing)

Is that 'bump' when opening and closing there w/ factory ammo? Sounds almost like you are hitting the cam lobe on the bolt. About the only time I noticed it on my gun was when I was running some 'warm-ish' loads. Let us know what you find.

Re: Yet another question( Neck Sizing)

Nope...Not with factory ammo. Here is a monkeywrench.

I measured one fire case with the stoney point headspace thingie [img]images/icons/smile.gif[/img] Tried to chamber the empty brass...Can do it but that little tick or bump is there and hard to close the bolt. Then I run it thru my F/L size die Now it gets good...Stoney point says it's the same damn size as before....no change on shoulder reading etc But now .............DRUM ROLL...It chambers fine.

Hmmmmm...This ones gonna keep me up at nights [img]images/icons/smile.gif[/img]
