Any one using H4350 in 6.5 PRC?

[Nellej12]

I have a good amount of H4350 and H-1000. Everyone looks to be running H-1000 or RL26. Will H4350 work for 143 to 156 grain Bullets?

I'm sure you could find a load that'll work fine using H4350, but you could very likely pressure out before you reach the velocities of RL26 and H1000.

Running the numbers through QL, for the heavy for caliber bullets, N570 appears to be the all out velocity king without getting into excessive pressures.

If that's the only two powders you have to work with.
I'd go with the H1000. You won't get the case fill with the H4350 without going over pressure
is my guess. ( as B23 said)
A friend of mine is running the RL26 and the Berger 156's with really good results.

H1000 and smk 150s work so well for me I didn't seriously test anything else. Tried RL 26 just to satisfy my curiosity. It gave about 50 fps faster velocity with less accuracy.

This list is from the load data sheet on Warner tools website. It is a partial list and for their 121 flatline, so I would start low and work up with caution. I’m sure you could find a load that will work with h4350, but will it do what you want accuracy and velocity wise I have no idea. I’ve used Norma mpr, h1000, and rl26 with good results.

From not only my experience with 6.5PRC but valid data on powder and charge I would say leave the H4350 out of your choices.
H4831 is a pretty good option but, all in all, the PRC needs slower powders than H4350.

H1000 would be a much better choice than H4350 but here is what I came up with Quickload for H4350 and the 156gr EOL

thanks, I talked to Berger Bullets this morning that they suggested to not even waste time trying to use H4350 in a PRC.

Would Accurate 4350 work with 6.5 PRC? haow many grains?

Probably, but why? H1000 is the holy grail in my 6.5 SAUM. 100% case fill and very low pressure will make for a little longer barrel life. Brass lasts forever. 4350, any of them, will run much higher pressures and temps to achieve the same thing with less case fill. No point in my experience. Shoot straight.

My grandson ended up using, N-565 and N-568 to get his, 6.5 PRC over 3,100 fps,.. w/ 140's.
Couldn't get Enough, StaBall HD in the case to achieve, 3,000 fps ( SADLY ! ) as We LIKEY them, Ball Powders !
StaBall 65 and Both of, the 4350's work FINE, in the Little, 6.5 Creed !
I Shoot LOTS of StaBall 65, in my 6 XC ( 95 gr + ) and 6.5 Creed with 130 gr M's and 143 gr., X Hornady's.
Yup,. I'm an ole' lazy, bastard and like, "Thrown Charges" whenever,.. "Possible" !

My curiosity forces me to ask why you feel 3100+ is necessary.
Did he find an super duper accuracy node there or just want speed?

@ shoot4fun,..
He wants to Try to, "Keep up" with his Little brothers, .270 WSM Clocking, 3,175 fps w/ 140 gr. Bergers ? !
LOL !
NO really, the 6.5 PRC w/140's, IS supposed to Go,.. 3,100 fps Plus, "easily" with, the RIGHT Powder.
Yes with, N-565 he gets 3,125fps and good group's, in the 3's and 4's from his, Proof 24" Barrel.
Sadly StaBall HD Powder was, a disappointment in the 65 PRC !
But StaBall HD Does, "work Well",.. in my Sons, 7 PRC ( 2987 fps w/ 180 gr Bullets ! )

N165 or N170 low burn temp like H1000 but more FPS, super clean.
