M1 Garand and Reloder 15.

[1903shooter]

Gents,


Need opinions on using Reloder 15 in the M1, 155gr and 168gr BTHP, Hornady and Nosler bullets. Load data would also be appreciated. Thanks, 1903shooter

Rx 15 has a moderate slow burning rate similar to 4320. It may be a little on the slow side for a Garand. It is slower burning than 4064, the powder normally considered the "slowest" for use in a Garand.

much better than I thought. no problems. about same results as Varget. I am pretty sure I was at least two grains under max and it functioned and ejected normally. unless you have an adjustable gas plug, you may not want to venture much higher.

I will second the good results with RL15. I use it exclusively in my garand. I do not have the load data handy but I am using Winchester FMJ/BT's. Accuracy is in my collector HRA is outstanding and no problems with function at all.

I tried using it one reloading session to cut down on the # of different powders I use and never looked back. Your mileage may vary with your bullet selection though.

HTH....

Hey Mr.1903, I can share what I can. Hornadays load data shows RL-15 for 168g as follows.
43.2=2300fps
44.6=2400fps
46.0=2500fps
47.5=2600fps{ max charge,use with caution }
they don't show RL-15 with a 150/155. but I can say I have used the hornaday 150bt-fmj with very good results. best I got was N-135 at 47.5g. sorry but Idon't remember the OAL, but ALL the canalure was still showing. I loaded to the bottom of the canalure, yes it looks funny, but shoots GREAT. for whats its worth, yesterday I shot some M-2 pull down bullets with Varget, 45g's worked really well. Hornaday shows data with Varget with the 150bt-fmj {which is close to RL-15} the following is with varget.
42.3=2400fps
44.2=2500fps
46.2=2600fps {max charge, use with caution }
this info came from Hornaday "for an M-1 Garand " not a bolt gun, most loading info is for bolt guns and will show higher charges. hope this helps.
