FWIW I had great success with basic load development using the speer .308 165gr boat tail soft point (pn 2034) in a mix brass, wlr prime, modest charge of TAC. Seated to about 2.725 oal in .308Win. Out of my bergara it was looking like a 1.5moa load with no tuning, probably 2moa in my brother's non-floated bushmaster. The loads cycled the gas gun, no issues with feeding that profile from the bushy mag or pmags.
I loaded the same bullet over a modest charge of H4895 in win cases, again WLR primers, and book length (I forget specifics) in 30-06 to shoot from my mauser 3000. It was around 1.5moa again, and I think it could do better as I was just shooting prone off a bag.
I got these bullets for $.19/ea on midway, which is cheaper than quite a few brands of fmj. Considering the price and performance over fmj, I'm going to order them in bulk asap (OOS currently). They also seem to work well on deer size game, so that's a plus, something ball won't do.
Since they were OOS, I got some unbranded 168gr BTHP factory seconds for $.20/ea, still cheaper than ball, to test. Hopefully they work.
