Yeah, that's a 30-round "score" of 300/25X. Again, fired from an unconventional supported position, with a bit more effort to uphold my end of the bargain. A clean trigger pull of 5 lbs helps a lot.
By chance, there were three other guys firing their M-faux also. Each one stopped by my firing point to ask why my rifle shot so much better than theirs. I didn't give them the old "Carnegie Hall" excuse (practice, practice), although going back forty years with the M16 system has a bit to do with it.
Instead I just said I made a few enhancements using readily available commercial products. I just didn't mention the gunsmithing skill that comes from doing several of these rifles.
I also realize that adding a target trigger to this rifle may not show any improvement in my performance. I may be maxed out with no further skill left to do even better with these rifles. It's humbling to realize that I may be building weapons that already exceed my modest skills. At least I know the performance is there in the rifle if I can ever move on to the next level.
The other thing that humbled me on the range was finding a fired S&W .500 case. I know the revolvers are hugh, but this was my first encounter with some of its ammo.
On the left is the puny .44Mag, and on the right is a skinny 5.56mm NATO. The .500S&W case is simply huge!
There are some sort of extractor marks 180 degrees apart on the rim, which is not typical of a revolver. I asked the guys behind the counter, and they couldn't recall what other type of firearm would use this round. One of life's little mysteries.
