Today was definitely Type 2 fun. I don’t think I am ever going to attend the winter S2H course. A tip of the hat to those who do!
Like you - maybe much worse - I have near zero interest in being a cold-weather shooting guru. But your mention of type-2 fun hooked me.
I dug my trek poles out (the ones with the arrow shaft shooting sticks hair-tied to them) and took the kids' 5.56 - the pink-trimmed one with the old duplex Leupold on it - and, since there's been several discussions of 400-yard holdovers here in the last few weeks, I went to do exactly that.
I walked to my 100-yard berm and plopped down in the driest spot I could find in the grass. It's cold here today, upper 20's when I was out, and windy/gusty, but fortunately my range is oriented to just south of east, and the wind today is mostly from the NW - almost a straight tailwind.
16" AR, 77TMKs over 23.0 of Benchmark, zeroed (confirmed the other day) at 225 yards. From my dry grass spot it was 396 yards, per rangefinder, to the target at my 500-yard berm.
Weather a minute ago (it was earlier and slightly cooler when I was out):
First two shots are the low-center splotch. I think the first was to the right, second more to the left, and the second obscured the first. Third was higher and right. The smaller splotch further low/left is .22lr from a week ago. 16" plate.
The duplex thick/thin intersection on the older Leupolds (3.5-10x set to 10x) is roughly 3moa. The steel plate is 16", so from the top of the plate to the center is roughly 2moa in this case. Drop, per my app, for this scenario is about 5.9MOA. Or, in short, use the bottom of the duplex as an aiming point and put it more or less 1moa above the top of the steel plate. Or 3+2+1=~6moa.
Easy enough on nice painted steel. Much more complex on an animal. To be completely honest I was expecting a larger cluster and the 'group' you see here exceeded my expectations. I do *not* want to attempt this on game. I simply have better options now. Three shots into MOA-ish, but to be clear this load over several dozen shots in the last six months has been ~1.75moa, so anything less than that is chance, not skill, and I'll be clear about that. But, yeah, it's do-able and in better light conditions (today I was more or less facing the sun which played heck with my eye focus) I'd do it *if I had to*. I'm glad I don't have to. We use this rifle almost entirely for hunting inside of ~300ish yards. Once in a while I'll let the kids shoot it beyond 300 but teaching them holdovers is fairly low on my list of stuff to do.
At 450 yards this particular setup would require another ~2moa of holdover. Heck no. I'd be lobbing them at that point.
