A 6mm follows me home...

[Hotshot]

Jim,

I always used IMR4831(remember when powder came in cans?). The short cut would be my preference now because I like the way it flows through a powder measure. A few 1/10's of a grain variation won't be as important with slow burning powder in a 6mm as it is in a small case with faster burning stuff.

I've got a couple hundred brass and a drawer full of 70 -100 grain bullets that I'll never use, but the stuff is stored at my daughter and son-in-law's house since I moved to Colorado. Have a little patience and I'll send you a list of good stuff at bargain prices.

To all,

Went out last week and conducted some velocity test with this thing (while there is still some good chronographing weather left and I was a tad surprised. The temp was around 75*, elevation is 440', 13' from muzzle to Chrony. I used the max loads I could find with the following powder, Rem 91/2 M, 75 VMAX and Remington brass. All were 5-shot groups, accuracy was not considered.

H4895, 40.0 gr, 3223 fps, SD; 27fps, Hi-LO; 73fps
IMR4064, 42.5gr, 3455 fps, SD; 12fps, Hi-Lo; 66fps
N135, 38.0**, 3297 fps, SD; 13.91, Hi-Lo; 33fps
Varget, 41.0, 3331 fps, SD; 44.5, Hi-Lo 104fps
RE-15, 40.4, 3748 fps, SD; 38.80, Hi-Lo; 112 fps
N540, 41.0 gr**, 3360, SD; 33.97, Hi-Lo; 86 fps
H4350, 49.0 gr, 3568 fps, SD; 16.72, Hi-Lo; 39 fps
H4831SC, 51.0, 3322 fps, SD; 15.10 fps, Hi-LO; 40 fps

** N135 & N540 loads were based on 243 WIN load data.

I was quite surprised at the velocities of RE-15 and will probably retest that load, otherwise I like H4350 and IMR4064.

Jim.......... Very nice report. Glad you got out to shoot her. I tried Varget when I 1st go my 6 Remmy and thought it to be to fast. I like the load volume of H-4350 and H-4831.
Good luck with her and hope she does well.
