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.

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.

Today I ran some Superformance and rewrote my sheet. And low and behold I can’t copy down numbers without screwing up.
What I found is Superformance needs 2grs more to equal N555. When I open up some H4350 I’ll be adding it to the sheet.

That is neat to have a sheet of powder comparisons for a certain rifle to keep in the notebook for future references. Which powders have worked best for you in that rifle?

RL17 by far the easiest.
Currently using N555 with the 115gr BT.

Sucks that RL powders are scarce. I like RL 22 for my 300 WM and RL 15 for my .308, but I like Varget better. I did a test today to verify claims about temp stability, ran out to the range early this morning to put a few @100 and @350 yards. Checked the Xero last time I tested, speed was at 3110 fps average with RL 22 / 180 Accubonds with 74.7 grains at 70 degrees and this morning was 55 degrees and speed dropped to 3085 fps average with no change @100 yards but a little low by an inch @350 from the last test @ 3110 fps, not much change to complain about. Pretty sure in the summer, speed will be close to the 3150 fps range.
