Re: 7mm RSAUM
"RL 17 seems a little fast for that. Let us know how it works out for you".
Actually, for me RL-17 gave me more velocity with less powder than anything else. I tried H-1000, IMR-4831, H4831SC, H4350, IMR-4064, RL-22. I got to 3000 fps with 67.7 grains of H-1000 and I got to about 3080 with 4064. Every other powder hit pressure between 2900 and 2950. With RL-17 I actually got up to 3130 or so and had lower ES and SD numbers than any other powder. At 58.3 I've got single digit ES and SD numbers, however, like I said above I still think it is too hot.
