Pick a Powder

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.

Waiting to hear your results. I only tried the 70 hammer hunters with varget. Tad under 3600 with 20" barrel and little tiny groups. Set my daughters 243 up for those. Great load with virtually no recoil.

.243 AI
26" 1/7.5" Twist Criterion Heavy Sporter
88gr Hammer Hunter
COL: 2.800
New Lapua brass
WLR
Jump: .055"
Crimp: Taper 1/2 turn

3rnds each of:

RL-17 - 44gr (space to go)
RL-23 - 47gr (Very Compressed)
XMR4350 - 45gr (Nice fill to bullet base)
VVN140 - 44gr (Space to go)
H100V - 46gr (Space to go)
StaBall - 44gr (Space to go)
IMR7977 - 50gr (Very Compressed)
VVN165 - 49gr (Compresed)

Find pressure, then find tuning round 1.

My vote is for the 4166 hopefully you post some results so I'll have a idea what to do with the 8 pounds I have.

 

[waveslayer]

I'd seek the 4166 or Dave it since it's discontinued. How are the redults without crimping your brass.

I like RL16 powder

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

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

If you find that holy grail 4166 load I'll give you my 2# so you'll have 10. You probably won't have enough to burn the barrel out, but should cover quite a few hog or coyote hunts.

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.

I've seen pictures of some Enduron containers where the lits coroded away. I suspect that had something to do with it.

..H-4350, mother's milk for about everything !

 

[Josh06]

I'd go Staball 6.5 if you can get a good load out of it because of availability. It's the only one of those that I see consistently in stock.
