I'm going to use h335 because that's what I am stacked deep with.
It's a plinking round so I am not expecting miracles.

That said my load books don't have 147gr with h335 loads.
Their h335 loads are all over the map for 150gr FMJs depending on the bullet type.
Online I have seen anywhere from 43grains being max to 49grains.
Where did you start? Right now I am thinking of starting to ladder test from 41 grains.

Also this will be fired out of a .308 AR not a Garand.

Hodgdon lists data from 40-44 gr for H335 for 150gr bullets. 147s are close enough in this case I use H335 for my 150gr FMJBTs, and its decently accurate. Cant recall the exact load ATM. Just be wary to drop 2gr off the top if you are using LC 7.62 cases.

Good luck. Never had any (accuracy) luck with H335 in our M1A's. IMR4895 came out best in our testing of multiple powders.

The AR10 might be different.

Thanks that is about the range I was thinking.

Yes. Works great. Best powder I have tried for 147-150gr. Bullets.

That's funny. While working up an accuracy load for our M1A LOADED I found found it very difficult to beat what we were getting with H-335. This was with Hornady 150gr SST.

Eventually I got a Varget load to shoot as well. This is 1 MOA with iron sights.

I've watched my son shoot plenty of groups with various 147-150 grain FMJ'S that were easily under 2" at 100 yards with the same rifle using H-335 and WC-844.

He was wanting a deer hunting load. We used the Hornady 150 grain spritzer boat tails. We tried Varget, IMR4895, H334, BLC2, Win 748 (can't remember if we tried IMR4064, but don't think so).

Guns are funny things. What shoots good in one doesn't work as well in another.

+1 I just bought a bunch of pulls and found 4895 to give the best results in both accuracy and reliability. The next best powder was BL(C) 2 but I dislike its sensitivity to temperature, which causes accuracy degradation.
