H4350 or XMR4350 - nice case fill, temp. change stable & accurate. I shoot rodents with a .243W using H4350 & 87 VMax bullets & sometimes temps are over 90 deg. F. Nice 400 yard performance with velocities at about 3200 fps.
44gr RL-17 doesn't fill the case to the base. Oh well, its a start load. Blow the case to AI anyway.

Heads up…they’ve discontinued the IMR enduron line. I’d be nervous to try the 4166 just because what if it’s the one!!!! ????🤣

I’d rather not know.

Rl17 will be the fastest I beleive. But not necessarily the best. Two different things sometimes
If I didn't have bad luck I wouldn't any luck at all. 🤪 It's good enough to blow the shoulders to AI.

3rnds each of:

RL-17 - 44gr (space to go)

XMR4350 - 45gr (Nice fill to bullet base)
VVN140 - 44gr (Space to go)

Find pressure, then find tuning round 1.

Indeed two different things but I’ve found hammers shoot best at or near top end velocity.

All the Enduron line?

I’ve been wanting to try some 8133 if I found it

IMR-4166 shoots awesome in my 257AI and 284 with the light Hammers. Often under .1 and single digit numbers.
With your heavier bullet, H-100V and Staball 6.5 would be good ones to test.

Yeah. I emailed hodgdon about it for confirmation and they said yes it’s all discontinued. sorry to be the bearer of bad news.

I was a fan of 8133 as well
I've seen pictures of some Enduron containers where the lits coroded away. I suspect that had something to do with it.
