Powder Comparison

[RL338]

This is no means a scientific data. I ran 3 powders along each side in the 25 Creed Striker , Hybrid 100V - RL-17 - N555.
My elaborate graph

Today I broke open the keg of N555 that I’ve had for awhile. My stash of RL-17 is getting quite low and now is the time find a replacement.
I’ve burned a fair amount of 100V and it falls short of RL-17 but it works in many cartridges for me.
By looking at the numbers 100V flattens out RL-17 keeps on climbing and N555 runs 2grains behind them. With all 3 44grs is a full case and then some. N555 doesn’t like to be compressed much , it’s like compressing sand , 45.5grs did put a good ring on the bullet.

Hybrid 100V and RL17 and almost 2 peas in a pod.
Hybrid may be your huckleberry.

I started using H100V for the first time recently and am really liking it. It meters well, produces good velocities for the amount used, and I'm able to find it on the shelf. Nothing to hate about it.

I have about 3.5 pounds of Hybid 100V left , not much more than RL-17 I have. I also have a keg of Superformance unopened yet. Online research hasn’t been very supportive of it. So today I decided to break the seal on the N555 that I’ve had for quite sometime.
The remaining RL-17 is being saved for the 7mm-08 , 375 Wby and 460 Wby hunting loads.

On my 6.5 Creed, my first powder development with the 123 grain MatchKings I used Hybrid100V and it gave great speed and accuracy. Used that powder for a while then settled for a hunting load with the ELD X and ELD 147 using the H4350. Stuck with that powder ever since in a variety of bullets. I would go back and try the Hybrid100V again if H4350 is not obtainable. As for Superformance and N555, I never experienced with them, and I can't remember what I used Rl17 for, it has been over 10 years since I used it for a load development trial.

Looking at the 100V performance, if you have any Staball 6.5 give that a try. If not it’s usually available.
