I had missed the extra posts since 2015 but noticed this last one. Interesting stuff.
Again, I haven't seen this fellow in a while so no updates except I maybe should have added that he told me he used to shoot approx. 15,000 rounds/year through his 1911 to stay proficient. He doesn't shoot that much anymore but that's the reason he wanted to use his 1911... familiarity and being comfortable with the gun. Of course he wouldn't have been shooting thousands or even hundreds of .45-08 rounds/per year, just load development/practice then carrying a few rounds for protection in the bush. We have lots of black bears here and now the grizzly population is getting unnervingly large.
In his case, he wouldn't likely shoot more than a very few .45-08's a year so not likely too much threat to the longevity of the gun.
I was looking forward to the load development and a good reason to get to the range. I have not been shooting much for some time due to a variety of factors but mostly too many things going on and not enough time. Got to make time!
Thanks all for the information. I have it stored away in case I ever decide to take this route.
