Recoil battering is not the only source of wear and tear on a gun, in fact, I'd say (IMHO, of course.) that the faster powders that are loaded with heavy bullets INCREASE wear and tear on the gun due to the fact that that they unlock while the pressure is so high that it erodes the flats on the barrel mating surfaces at the rear.
I have no proof of this, but I notice a lot of the shooters that load heavy and fast have overbuilt guns that are made for this sort of thing. From what I've seen, the stock guns that are shot heavy and fast take a real beating from major loads. I would have to ASSUME that the loads in question are not book loads, but ones that have been 'proven safe' by shooters with the aforementioned 'overbuilt' guns.
If you go by the book, you're prolly in the clear in most cases.
Sometimes not, but it's a small price to pay for faster splits. Flogging hardware is nothing new to me, and I'd assume it's nothing new to gun gamers, either. No disrespect.
I wish I had the skills to compete, but I don't.
I don't bs myself by saying stuff like 'If I had more practice', yeah, I'd get better, but not good enough.
It's still fun to play around with, but I have found that 'improving' the gun and ammo is secondary to improving my skills and it's my job to adapt to the gun, not the other way around.
