Yup, agree 100% with distances and capability.A kneeling or seated position with a good bag off a tripod or preferably a rock or log, in known conditions, I have zero concern shooting at 400 yards on an animal. My wobble zone is next to nothing if I can get in a spot where I can support my trigger arm with my knee.
To provide some context I’m also not even considering a shot over 500 yards on a big game animal.
Of course I have hit targets much further. Last nrl hunter match I shot, If the md didnt provide natural feature to shoot off, and the shot wasn’t prone, my second choice was the bag and plate on the tripod.
Locked into a tripod with ARCA, I am 100% comfortable going beyond 400. Inside that, the bag killing stuff.
I have guys running the ultralight plate bag combo in the NRL, one of them is local match director. So, I think that there is some preference with bag weight. And, they choose to run of a tree, stump, rock, etc.
Getting that rear support with a knee makes a huge difference. And, if someone can set up a second tripod as rear support of some kind, that makes a huge difference.
When I am able to get guys to spend 20 minutes showing them how I can help them build a position and dry fire, and if circumstances allow it in the field, they are lethal to the 400 yards kneeling, sitting off a tripod.
Standing off a tripod requires a larger set of skills and techniques.
