Nickudu,

Most excellent, thanks for posting.

Bob

I am quite sensitive to that fact Jeffe, so I'm hurrying the pace. Note the relationship of RL-7 / IMR-4320, when driving heavy bullets with a marginal powder space. I found the same to be so in regard to the Lott, especially with the monolithic Barnes.

IMO, "THIS" is what the .458 Winchester Magnum should have been, not the Lott.
A standard action, utilitarian big bore. I've seen 3 or 5 of these that gave 2,300 fps. with 24"+ barrels.

Nick,

Excellent point, on RL-7 vs 4320. I used RL 7 in both, a very heavy loaded Ruger 1 in 45-70, and again in a 458 Winny Ruger 77 for 2125 FPS with 500 grain Hornaday Soft.

Also little known is that RL-15 has almost the same burn rate as IMR 4320. I've worked up loads with RL-15 using 4320 starting load data as a beginning point. Also, RL-15 is "almost" identical to the old Norma 203. I have again used RL-15 in cases where Norma 203 was listed as "best" and there was a time that N203 was unobtainable.

Regards,

Bob

RL 7 "small bore rifle powder" kicks ASS in 458 win.

Thanks for doign it quick, Nick... I would have like 100#of actions, 180 of barrels, and 3 walnut trees, all waiting for my time!!

jeffe

Have any of you found RL 7 to be temperature sensitive?

it really seems to get upset at about 500F when the primer goes!!!

just kinding

DB Bill,
It was 115 degrees for most of my 14 days in the Valley, October '99. The Lott, with the RL-7 loads, gave no noticable indication of increased pressure. I had mic'd the fired casings, upon arriving home, with just this thought in mind.

Left in the sun, any powder will do likewise.
