AR 10 243win loads

[odie]

Acquired a stock DPMS LR243 and am looking for some loading data for the heavier bullets 87gr and up. I know the AR platform has to be run with less pressures than a bolt gun. Loaded for bolt guns for close to 40 years. ARs I do not have much experance.
Thanks in advance

I have a LR series DPMS AR-10 with the 20" 243WIN Hunter barrel. I'm shooting the 87gr. V-Max bullets just under 1" MOA without any issues with 35.5gr. IMR3031 powder. I haven't chronograph this load.

Sierra accuracy load of 4064 with 87 and 85, lights out in both my 243s

Is this load out of an AR or a bolt gun?

Probably want to stay on the faster side of the available powder options. With 100+gr bullets, Win760, H414, IMR 4350, IMR 4451 all look nice and are on the faster side of the available options. 4451 (looks particularly good) with high velocities, reasonable pressures and modest charge weights but I don't know about case fill %age.

Bolt gun. Am planning an AR in 243 and these will be the first loads I try in it as well

I should add that RL-15 performs admirably as well in the 85-105 weight range and is on the faster side of acceptable 243 powders. As with 4064 noted previously, all my experience to date is with bolt rifles.
