Sierra Heavy TMK 6MM Testing

I’ve used JBMs in the past for plastic tipped bullets but I’m just WAG’ing and extrapolating from results with 106 TAP that is a similar aggressive profile bullet.

Be interested in what the calc says at sea level DAs and a little below.

Edit: crap, didn’t see you were just asking about DA..NOAA has a DA calculator. I’ve seen graphs on here with elevation and temp correlations. I just use kestrel or RF.
I’m sub 1.5 sg according to AB at -500 yesterday. That’s in a 7.5 twist. In the slower stuff I think a 7 twist isn’t going to hurt any.
