[QUOTE="freddiej, post: 2000445, member: 26227"] Steve, Chronos are wonderful if you are shooting long range target and would like to see if your load is consistent. if your brass is consistent, and your powder is performing like you want it to. For hunting applications they are nice to know what your true speed is. so know someone that has one and borrow it once in a while for new loads and such. for me, a gunsmith, I use a friend's Chrono when I have a perplexing problem with primers failing or piercing or blowing out. sometimes the only pressure sighns are a hole in the primer and I like to know if the load it just too high pressured (too fast for the estimated speed of the load). I had a 308win Rem 700 long range target that no matter what you put in it the primers would blow out and the small piece of the primer would be found in the bolt body along side or in the striker spring. I even loaded minimum loads from my pet loads and they were over pressured. I cast the chamber and it was nearly 0.002" below minimum SAAMI. or said another way; 0.001" over the round in every dimension. A recipe for disaster. I sent it back to Remington and they finished the chamber with another reamer. all problems solved. you do not need to have a chrono, I would put it on the "it's nice to have" list. I would not put it on the "necessity" list. [/QUOTE]
