A 165gr Nosler Accubond pushed by 58gr H4350 for a muzzle velocity of 2860 fps was always my "go to" in my custom barreled 30.06(25" Pac Nor). Accuracy has always been stellar with this load producing consistent 3/4"( or better) 3-shot groups at 100 yds.

But, difficulty finding H4350 has caused me to start experimenting with Alliant's newer RL-16. Boy am I glad I did. This past weekend I found that 57gr of RL-16 will put 3 165gr Accubonds into 0.6" at 100 yds at 2915 fps over my chronograph. 57.4gr(Alliant's Max) produced 2942 fps! First 2 shots went into 1 ragged hole! I pulled the 3rd shot an inch to the right, so I'll need to confirm accuracy again on that one. I'll add that the ES and SD on these two RL-16 recipes were in the single digits! Temp was 81 degrees while shooting.

Temperature stability and de-coppering agent to boot with RL-16!

Looks like I may not need H4350 in the future!😁
