Well, the board is either fixed, or it's going to run terribly. Cross your fingers and hope for the best. I'm at my technical limit right now.

Reloading 30-40 Krag

#1 Post by Hippycrowe » Sun May 20, 2018 3:15 pm

I picked up a Krag really cheap I was going to re sell it but thought about keeping it and reloading for it. Is the Krag as easy to reload for as other rifles. It .5 on a muzzle gauge so its pretty tight kinda rough bore but still has rifling I have heard guys shoot 308 and 310 bullets in them. I have never reloaded a 122 year old rifle before. I have also read flat base 220 grain bullets are best. What are the best loads you guys have used in the Krag

Slug the barrel. I find it easy to load for and like the 200-grain or better cast bullets. Brass is also easier to find now, than it was in the past.

I have to find some lead balls to slug it it too bad they didn't clean these rifles better. This one is a parade rifle with good rifling just a ton of haze in the lands. Not sure who makes the best 220 grain bullet.

A flat base,round nose heavy bullet is the way to go. I shoot the 220's out to 800 yards and they shoot very well. There are so many loads to choose from on the web that you should be able to find one that will shoot well for you. " The Rail Puncher" cartridge is under appreciated. The rifle is stronger than the lies on the internet written about it.

Hip:

I think I have some 31-cal lead roundballs that I can send out to you along with those Sierra bullets.

Thanks I used get them from a friend but he has all his stuff stored away. Do guys really resize 303 into 30-40 I figured they were to different to do that

I tried resizing 303 Britsh in a 30/40 die and they worked fine. The neck is a little short but it doesn't seem to matter. I used the starting load data.

Just to springboard off Kurt's comments, if reforming FIRED .303 British brass to .30-40 use the least amount of resizing that will allow a round to chamber. In fact, just a tiny bit of rotational bolt drag is probably a good thing. It lets you know that the shoulder area of the case is touching the shoulder area of the chamber.

The rationale is that .303 British chambers are notoriously oversized with respect to diameter and length so fired brass is often stretched in the web area of the case as the shoulder gets blown forward and the web area of the case expands. You don't want to set the shoulders back on these fired cases any further than necessary when resizing, else it is not uncommon to experience a case head separation when the shoulder blows forward again, and gas venting is not as good on a Krag as it is on more modern rifles, IMHO.

Case life when firing re-formed used .303 brass will vary significantly depending on just how tight or loose the chamber was when that .303 round was originally fired. Note that this has nothing to do with headspacing, which on a rimmed case is all in the rim and not in the shoulder area.

For what it's worth, Graf's currently has new CapTech brand .30-40 brass for under 30 cents a case, about the same cost as new .303 British cases, so there's really no reason to reform NEW .303 British cases if you can get new .30-40 cases for the same cost (or so I believe). I should mention that I have never used CapTech brass so I really don't know how good it is.

Thanks for the info I am going to order some of the brass. The rifle bore is rough but it shoots her accurate
