Guys who are serious shooters that want a 7.62 Lee Enfield should buy or build one on a No.4 action that isn't worn out. Even then, you're stressing them to the max so you must adhere to the military specification pressures. Those who want to push 168 and heavier projectiles at M118LR velocity, (yes, I've seen and repaired the results once. He was lucky.), are beating their old rifles to death. Stick with the 155 grain Palma Match SMK and you should be fine.
