41.5 of RL17 drives my 140SMK about 2900FPS out of a 26” Bartlein. Yes, this is in a Hornady book. BR-2 Primers.
5 shot groups cloverleafed and about dime size at 100YDS.
SD-5FPS
ZERO pressure issues and I am on my 15th reload with Win brass. Tight primer pockets and consistent neck tension.
RL17 runs circles around the love of everyone’s life, H4350. It is temp stable, VERY consistent FPS, costs far less and almost everyone has it in stock.
I always snicker when I see people loose their minds over H4350.
Hodgdon pulled an amazing marketing trick with 308 168gr Amax loads from Hornady.
It used to be they printed on the box of ammo something to the effect of “To duplicate this loading H4350 may be used”.
And people lost their damn minds. NOWHERE did it ever say H4350 was the exact powder used.
ETA: This loading is Supersonic to 1200yds per numerous calculators.
