Multiple Rifles Same Caliber

Canuckenstein

This is a quick question. I own 6 rifles all chambered in the same caliber. I have a M96,M38,M-41B,AG-42 Ljungman and 2 CG-63 (Sporterized Mausers used in Swede style CMP program). All chambered 6.5x55 Swede.

So if you were reloading for all these would you segregate the brass? Or FL shoulder bump .002-.003. Call it good? I have duplicated the m41 prickskytte load. Which shoots extremely well in all of them.

What would you do in these situations? Looking forward to everybody’s input.

How sure are you that "bumping them .002 - .003" will produce the same length afterwards?

You'll have to measure and compare fully fire formed cases; more likely than not, the "starting point" for each rifle will be different, and hence your setup to bump will also be different, resulting in different sized ammo after you are done.
 
I would purchase a box of commercial ammo and size all my cases to that standard on the premise that between the six rifles the headspace could be slightly different but all should chamber and fire commercial ammo with no problem

Bumped one took the firing pins out all of them and chambered that case, in them all the bolts dropped freely on all of them. The ljungman I took the recoil spring out, smoked the shoulders of the case with a zippo. Chambered it and pushed the bolt and carrier into battery. The soot was not touched but the chambers shoulder. Did the scotch tape trick afterwards on all of the and it would not chamber. In any of them.
 
Then I would call you very fortunate indeed, and your plan should work a treat. The only thing that may still cause a difference in loading is if you want to tweak seating per rifle (may be necessary if you have different barrel profiles/lengths).
 
Just full length size and call it good. Trying to dial something in for six different rifles will not gain anything.
 
You are very fortunate to have them all so close . I would say you are good to go with your plan . I had two 96s that were close so I did the same as what you plan . I did find they shot best with a seating depth all their own for bullet/load . Not a huge difference . Good luck , I have always admired the 6.5 x 55mm .
 
Usually, I'll only segregate cases for different rifles only if I must. Normally, one batch of brass will work fine in different rifles with no adverse effects. One big exception: In situations where I use, for example in .308, brass for full-power jacketed bullet loads and brass for lowered-powered cast bullet loads, I keep the brass separated.
 
I have multiple multiples of 25 caliber. I don’t shoot much anymore so the ones I am trying to wear out get factory.
 
I have multiples of three calibers. Each rifle has it own set of dedicated cases.

I found this is the most effective way to control uniform and optimum shoulder bump and keep track of rounds fired in each rifle. Some of my rifles require a different die setting than others to achieve optimum shoulder bump - one size doesn't fit all in my in rifles.

In addition, each rifle has a different chamber length thus each has a different max. case length that I monitor to determine when it's time to trim.

I LOVE your selection of variety. Does your AG42 hurt the brass?

It can dent the mouths pretty nasty but the bodies and shoulders are usually fine. Unlike my SKS model D ( made by Norinco takes AK mags) if you fire brass cased through it leave it were it falls. Because that rifle destroys it. The Norinco Type 97 of mine is the exact same. Must be a chi com thing.

I was using the Model D to varmint some ground hogs living in our ranges berms (not anymore). I reloaded some nice Nosler varmaggedens. Went to grab the brass. And it was massivly dented below the shoulder.

I’m kinda thinking I may go that route aswell. Your methodology makes sense to me. My thinking is the CG’s are to have developed loads. Where as the Milsurps will have a m/41 prickskytte clone loaded for them.
 
Before "bumping them all .003" or so", I take it you want to interchange the rounds to shoot in all rifles. If so, I'd take a couple of fired cases from each rifle, measure the base to shoulder to find the shortest one - then bump .003 from that one. I'd also look at the difference between the shortest one and the longest one to see how big the spread is. If it were, say .008" or .010" (or more), you might opt to keep brass segregated to each rifle as brass stretch on the rifles with the longer chambers will cause your brass to wear out a lot sooner and likely result in reduced accuracy in those with the longer chambers as well.
 
I own 4 rifles in 300WM, then there is another 3 barrels in 300WM for one of those in different lengths. Each rifle/barrel has it’s own FL die and each have their own 200 cases. I have 3 Redding Comp seater dies that go with each barrel and another that is used for the other rifles.
I also have the same in 338WM, 25-06 and 264WM. They all get their own batch of brass and FL die.
I use Forster dies and have the necks honed to my specs. Have also honed RCBS dies with success, but setting this up was costly.
I ran the gauntlet years ago trying brass from one rifle in another, it only worked one way for me, the smaller chamber would not except the larger chambers brass, so that was that.
Great cartridge choice, I’ve had a Model ‘96 and M38 in 6.5x55 myself, both Carl Gustav made rifles.

Cheers.
 
A first firing based on being say 0 to -0.002" below SAAMI would usually guarantee that ammo should fire in the rigs that would pass gages, but after having to account for what happens after several rifles and several cycles depends on several chamber dimensions and some statistical luck.

Chamber necks, headspaces, body diameters, etc, may or may not all treat that brass the same. If all of your rigs are reasonable and you don't have any that are really loose fit chambers, you should be able to run that brass through all of them. Only you can answer if all of those rigs are very similar or if they are all over the map.

I run many 30-06 rifles in a similar way for many years... and then I got one where the body was wider down near the web and it ended that streak. The brass from that one stays with it and doesn't go to the others. YMMV
