I have opportunity to buy 1000 Federal +P 158 grain LSWHP at about 50 cents each. I thought this was a great price till I got to reading some of the review's. There was a a bunch of reviews that said by the 3rd shot in a J frame the cylinder would lock up where the bullet would slide forward in the case during recoil. Per the reviews the lighter the J frame the worse the problem. A[so it said these bullets are not crimped in so running them back through a crimp die doesn't seem like a good idea as there would have to be a psi increase. I didn't see where anyone was having issues with a full size .38/.357. I had been wanting to try some of these loads but have been unable to find until now. My question is is bullet moving out of the case under recoil something that you know first hand occurs with these rounds or just internet rumors? I hate to buy 1000 rounds knowing I can't use any in a J frame. Thanks!
