Seems like a good match but no data available that I have found. My R15 loads do alright but got a couple pounds of R16 for other cases and am curious if I can find equal or better velocity and accuracy with more temperature stability with R16. R17 has potential but less stability than 16. What I am finding is I can use R15 data for 16 and go up to or almost to R17 data in some cases.

In that round RL-15 works so well seems few want to venture into other options.

And not much incentive to squeeze an extra few fps when you got a good load.

Yes this has kept me from trying anything else but R15 with 250 gr loads but I have gotten pressure signs in hot weather so improved temperature stability would be a plus.

Later lots of RL-15 are reportedly more temp stable.

Seems competition for military contracts has had a positive effect.

DF

I load 69gr of rl15 under 235 speers. They shoot very well. put a deer on its ass with not much meat damage

Phoneman what velocity are you getting with that load?
