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.
Rather than spend my hard earned pennies on those cool Shoot-N-See targets or even the preprinted targets at sporting goods stores, I save a few bucks for weekend plinking sessions by using paper plates as targets. A 100 count pack of paper plates costs less than a 10 count pack of preprinted targets.
If you are playing with something like a semi auto AK, or building a young shooters confidence with a 22 or shotgun, those big eight inch blanks are perfect for putting holes in all...
