I have pretty much everything I need to reload except for one crucial element, bullets. Turns out those are mighty important in the reloading process. I have a bunch on order but theyre not here yet. I was in the mood to setup all my dies last night and I realized I would need a loose bullet in order to do execute the bullet seating and crimp step. I dont know if it is advised or not, but I took my bullet puller and decided to pull some factory rounds and previous reloads I had lying around, just so I could get my die setup. This is where I ran into some interesting variances using the hammer-type inertia bullet puller. I stuck in an old reloaded round and was able to get the bullet out after about 2 or 3 whacks. After the bullet fell out I realized it was 124gr and I wanted to setup my die for 115gr (didnt know if it made a difference or not, but wanted to be consistent). I grabbed a PMC 115gr and proceeded to whack the **** out of the round but could not get the bullet loose! The girlfriend wanted to have a go, but her muscular arms couldnt get it to budge. After about 15 or 20 whacks I gave up and tried a Remington 115gr round. After three whacks the Remington bullet came out. Then I grabbed one of the handloads I made at Johns reloading class a couple weeks ago and after only ONE strong whack the bullet came out. Maybe this isnt a big deal but this seemed quite a difference between the manufacturers! My question is how does one know when they have enough crimp? Ive seen pictures of too much crimp where you can actually see the casing almost turning inward towards the bullet, but I think Im more concerned on the low end. I positioned one of the loose bullets in my expanded casing and sent it up to the bullet seat/crimp die and it felt like barely anything happened (as far as resistance on the handle). When I dropped it down and measured, the OAL was fairly close to where it needed to be (havent had a chance to dial it in yet, but will). In the class I took, one way we were shown to test if the crimp is strong enough is to drop it in the magazine and slam the slide forward loading the round. After a couple of times check the length with calipers and see if it has moved at all. I did this with my Beretta and after 3 slams it had moved +.02. Is this ok/acceptable for crimp? Should I put more? I understand too much crimp is dangerous because of pressures and such, but is too little of crimp dangerous as well?
