Well I have most the parts for my next rifle sitting in my closet. It is going to be a big 7mm of some sort. Most likely a STW or RUM. I have an 8 twist Shillen that can finish at 30" but I'm kind of concerned that I might push the 180's too fast. I wanted to use the 195's but I am kind of tired of waiting and want to start shooting. So has anybody pushed these too fast to failure? Too fast for accuracy? This won't be a plinker so barrel life isn't at the top of the list. Really I want something that is at the top of the heap ballisticly to poke at deer way out there and elk less way out there. Thanks for your help.
