Hi all,Im looking for your most accurate load data and flattest shooting load data with a FNAR with a 20" barrel using 150 gr nosler bt.Thanks in advance for your info.
 
Probably should just work up your own load. All rifles are different, Yours make not like Someone else's loads. And since your hand loading ammo. You always start low and work up.

You should post what powders you have on hand. I have a number of accurate 155 OTM loads using Varget, H-4895, IMR 4064, Reloader 15, AR-Comp and IMR 8208 XBR in my GAP 10. As in all hand loading procedures, you will need to start low and work up a safe load in your rifle. Gas guns usually cannot take the same powder charges a bolt gun will.

My .308 Win. gas gun powder charges are usually 1-2 grains lower than my bolt gun loads.
 
My best loads for 150-155 grain bullets have been 42.5 H4895, 44 Win 748 and 45 Varget all in LC brass. If in winchester commercial add a grain or so. Seating depth varies from 2.72 to 2.815" depending on bullet type, whether long match bullet or short stubby hunting bullet.

This is not for an FNAR. I don't own an FNAR. However I think that if you took those loads, shaved a grain and a half off and worked up for yours it would shoot well. It is especially hard to go wrong with varget or H4895 in a 308.
 
I have worked up my own load and 44.5 great varget gives the tightest groups at 100 but drops like a rock at longer ranges and I'm concerned with pressures with varget at higher loads.just trying to get advice. I'm well aware I should work up my own I didn't realize this room was so arrogant.sorry to bother you guys
