Introducing the Absolute Hammer

[new2mud]

Well Superformance is out for me, I just tested it today and from 80F to 50F I lost 75 fps while my 153 Berger/H1000 loads are almost exactly the same. Going to get into it again tomorrow with Hybrid 100V in the 6.5 PRC with the 109gr and 123gr and the 178's in a .300 win mag.

Looking forward to the H100V/123 results.

Guess I'm moving to RL 23
It shot about the same and I have some

Well, this should find me pressure somewhere. The last load of 42.5gr was about 98% case full with Lapua brass and the 123 seated at 2.875.

Well I just shot a little. Loaded up some 123 ah with some newly aquired H100v. Dont know why with the rifle doing so well with RL-26.( 6.5x257 weatherby 1-9 twist) But you know...Any way loaded 59g H100v 3.400 col fed 215m. Pretty light load, but about a 3 inch group. Yuck. Upon further examination I discovered the bullets are key holing the target. Dont know why but I guess I will be pulling the rest of the ladder and just sticking with the RL-26. Buoght some superformance too...Why cant we just leave well enough alone?LOL

Here is the RL-26 Data. Why do you guys think it wont stabilize the 123's with H100V?

They're meant for a 1-8 twist, and when Steve recommends an 8, that's the minimum. It's more for terminal performance. You are getting enough velocity at your elevation with the R26 to probably just barely stabilize them. The 109's should absolutely scream in your bee, and it would stabilize them.

Maybe rate of twist is near the unstable twist zone.
How far apart are the RE26 velocity vs the 100V ladder velocity?

 

[wwac2]

I read that before I bought them, but had to try. I loaded 59, 60, 61, 62 and 63 grains of the H100V. Would you move on up or just stick with the RL-26. Will be headed to Colorado in a month deer hunting/ long range shooting. Im sure it will be stable there. If not, I will have the ole trusty MOA 270wsm and 170g eol's

Im not sure at this point. Crony is all over the place. My buddy knocked it off the bench last week. The 59g h100v was a very light load though

 

[GLTaylor]

You've got them loaded. Go ahead and shoot them. Given your low altitude, like already stated, you are probably at marginal stability (at best). Check the Berger Stability table. The only possible help is speed - but that help is limited by your slow twist.

 

[GLTaylor]

Looked at your speed with R26. It's 3515. You might stabilize if you can reach or exceed that speed with 100V?

 

[Ed AO]

Disappointed to here about the bad temp stability with superformance.

 

[Gord0]

Might be helpful for some of you looking for temp stability.

And for reference again.

Anybody with experience on RL 23? A lot of the Reloder powders seem to fluctuate a good bit too?
