Anybody seen this RE TS 15.5 yet?

If one of you guys don’t mind, please post some 223 and 308 case fill numbers with 15.5 ts. The load data looks somewhat ambitious with what I have heard is Reloder 16 kernel size.

Thanks
Jim
 
Well I did a short ladder with R-15.5 in my 284-ELF ( a really
short 284 Winchester cat of mine) My match ammo I settled
on uses IMR-4166. So with all things equal, I just basically
substituted powders. and shot 5 groups of 4 to get a simple
look. Targets were not that spectacular with just a powder
switch, And velocities were slow. 4166 is way faster and used
2/10ths increment's. 2/10ths with R-15.5 looked pretty flat.
At least I'm ball parked for work down the road.
 
Tested RL15.5 last week, had some promising groups at 600yd, my barrel seems to like 32.5 and 32.6 grains, haven’t played with seating depth yet, just jammed Roy’s 103’s 0,005 to start with
Shot our club match this weekend and my four target agg was 2.007” , I cal live with that :=)

You are correct, totally, in your thinking. Here is the information you want, with 3 different cases filled to top. I could fit 25.1 grains in the case with a 77 SMK and load to 2.260, but it would require so much force to seat, it would be incredible.
Reloader 15.5 Review

I will not use this powder for 223, its way too bulky. This powder makes little sense to use for 223. You would use AR Comp, or N140, or Varget, or SW PR, or you name it, is better.

I am testing this in Valk right now. That will be far, far better. As I already use RL16 in Valk and think its great.

1 kernel of this powder, is about .025 grains. So 4 kernels is about .1 grains. So basically, 1 kernel has a FPS impact of about 3-5 FPS. estimation, not a fact.
 
I had my focus on some bolts I had to shorten for a different bottom metal, and in that much time I missed again.... you blink and you miss this...
