I've been reading on the reloading forums quite a bit lately about crimping high powered rifle cartridges. My question is, has anyone done any investigation if crimping improves accuracy? People on one forum claims crimping does inprove accuracy, while others on the same forum say it makes no difference, that crimping is done only to keep bullets from pushing in on lever-action rifles. Also, does crimping increase pressures? Well, I guess that is enough damage for one session. Thank you ... Tom Purdom
