Whiskey James SASS 85199 Posted February 27, 2011 Posted February 27, 2011 Howdy all, I've been noticing that the majority of my spent cases still have a slight crimp. This is with both .357 and .45lc. Both are loaded with Trail boss at the minimun IMR recomendations. Just wondering is this is ok or am I doing something wrong. thanks, Whiskey James
Black Tooth Zach Posted February 27, 2011 Posted February 27, 2011 Is the minimum load not enough 'bang' to fire-form the brass and make it straight? Does this cause extra lead fouling because the bullet sides are 'scraped' by the crimp? Is there too much crimp? I have no answers for you, only more questons. We'll see what the experts say.

Bramble Mountain Buzzard Posted February 27, 2011 Posted February 27, 2011 My experience with Trail Boss is that the bottle neck cartridges are OK at the minimum. Whereas the straight wall need to be bumped up to around the middle for complete ignition, pressures and such... One of the many reasons that I switched to Promo...
Chickahominy Charlie Posted February 28, 2011 Posted February 28, 2011 I think that's probably right.....there ain't enough "bang" to straighten it back out all the way. I don't see where it would hurt anything...you're just gonna bell it out again at the reloading bench, right? Chick
Whiskey James SASS 85199 Posted February 28, 2011 Author Posted February 28, 2011 Thanks all, They seem to do just fine going back through the reloading process. Whiskey
Cheyenne Culpepper 32827 Posted February 28, 2011 Posted February 28, 2011 Mine are like that, most likely from a tight crimp, which I like to ensure the boolit won't collapse into the case. I shoot 3.2 gr of clays, just over 900fps so it's not like the lite load theory holds much weight. I think it does shorten case life tho... Cheyenne
Captain Woodrow Cahill, SASS # 54363 Posted February 28, 2011 Posted February 28, 2011 Howdy James - I wouldn't fret about it. A good tight crimp is better than too loose. Resizing & belling will take care of it. I wouldn't worry about shortening the case life too much either - you're more likely to lose the brass in the weeds than to split it.
