Do I need to have my rifle's headspace checked?
I've got a stevens 200 in .22-250, I'm getting slight case bulge as you can see below. This is off the shelf winchester white box ammo. Is this caused by headspacing or something else? I'd like to start reloading would these cases be bad to use, I'd like to get a full length die set.

Just keep an eye on the brass length, they may need to be trimmed from time to time.
Great quality pictures by the way!Last edited by 762xIan; March 11th, 2010 at 07:57 PM.

Re: Do I need to have my rifle's headspace checked?
Yes, that is completely normal to see that on rifle cases. You have to also remember that down towards the case head, the brass in that area (the web)gets thicker to help keep the case from rupturing.
As said, if that brass is only going to be used in that gun, ll you have to do when reloading is to size the neck area, no need in stressing the whole case if it doesn't need it. If you were going to shoot your reloads in several different guns, then you would want to full length resize it to insure it chambers in all the guns it be fired from.Ron USAF Ret E-8 FFL01/SOT3 NRA Benefactor Member

Seems very normal, just watch your length. Sometimes if you have real deformation you can increase in length dramaticaly. Happy shooting. Groundhogs are fat aproaching. I got one already.

Re: Do I need to have my rifle's headspace checked?
It must just be me but............................
Looking at the fired cartridge, since they are close to being the same in scale,
ther are two things i notice; 1. The bulge at the base and 2. To me it appears that the shoulder on the fired case is now bigger than the unfired case.
Do you have a dial calliper? If so, measure the shoulders of unfired and fired and see if there is a difference.
My first clance says there is. If the fired shoulder is larger, and the neck shorter, then, the case is backing up during firing and you get the base bulge AND the larger shoulder.
A quick check will be to put a piece of masking tape on the base of an unfired
factory cartridge, cleaning off any overlapping tape, and see if the bolt closes easy (don't force it). If it still closes, your headspace is off about .003 in., and it needs fixin'. Otherwise, you'll eventually split your cases at the base after a few reloads.
Also, out of curiosity, measure the bulge diameter and also the original base diameter, and see if they are the same.
I am aware that the case sticks out of the chamber some when it's chambered, but the bulge seems a tad inordinate to me.
Usually the portion of the case sticking out is just the webbing area, which doesn't bulge.
I'm probably wrong (and I hope I am), but it looks to me like the case is backing up when fired, which means headspace.
I'd get it looked at myself, or at least try the tape test.

Re: Do I need to have my rifle's headspace checked?
I'll bust out the caliper tomorrow and get back with some measurements. I did notice there is clearly less of a radius at the start of the shoulder on the fired case. I would have it at the smith yesterday, just to be safe, if he didn't take so darn long. Hard to find someone I trust that doesn't take forever.
