Thank you for making my point.Hunting season is coming up and we will see how my methods works out when there are animals to shoot. Or the curious can go back to past hunting seasons and see how it worked out for me in the past.
My normal hunting rifles are so over bore that if I get 500 rounds of accurate barrel life I will count it a good thing and if I get more then that is just extra gravy. My issues are carbon ring and throat erosion. Copper running over stainless steel at high speed is the least of my issues.
Some of us don't have unlimited budgets nor the desire to replace a barrel every 500 rounds.
