I'm going to start loading for my K31 very soon and am curious if anyone has advice on whether or not to crimp the rounds? My K31 has a detachable box magazine and I don't know if the recoil will be enough to 'jack up' the bullet seating.
For hunting loads I never crimp. If using expanding hunting type bullets the recoil of the rifle will often cause the bullet tips to very slightly deform in the magazine long before they push the bullet seat deeper. In other words the points of the jacketed bullets, especially if exposed lead, will slightly flatten. I'd only worry about crimps in semi-autos.
don't crimp anything eiterh but then I've never loaded for an auto loader. I guess those guys do crimp. Your's is a bolt and I just don't see the need. I think that the same case as the 6.5x55 and I never crimp it. But the recoil could move the bullet I guess. Never did in either of my 338 mags Though. Just load without and see what happens. You can always run the ammo thru the seater again and crimp them.
I must admit that I have missed a big game animal with a rifle. And not only was it a bull elk, it was the largest bull that I have had in my sights with a tag in my hand. But, as with most "missed shot" stories, I have an excuse. Moisture doesn't really ever bode well for hunting equipment. When moisture (either rain or snow) gets into a firearms barrel, nothing good takes place. A couple rain drops down there can change the point of impact drastically and a barrel jammed with snow after a...
