Re: 22-243 loads
Silver, I don't know where you got the chart, but I don't agree with it at all. Your chart says that in a .22 caliber shooting H1000 A person would get 500 rounds out of a barrel. My 22-243 has 1000 rounds through it shooting Retumbo and still shoots bugholes. I have a 6.5-06AI with over 1500 rounds through it and still shoots less than half inch.
