How sensitive is R-26?

Thanks


Smoke....

I've been running it exclusively in a 6CM with 108 ELDMs @ 3158 and have found it to be very temp stable. I have not had a chance to run it in temps below about 70* here, but maybe we'll get some winter weather come Dec/Jan....grin...

Ran a match with it in August that was fast paced, very little time for the barrel/chamber to cool between 10 shot strings. Temps started in mid 70s and was 108 when we finished. Didn't see any weird vertical dispersion or pressure show up through the day, even with a few rounds getting baked in the chamber pretty good. Ran those same loads over a MagnetoSpeed on a different day with the same temp variance and the FPS change was negligible.

I've tried it in a few other chamberings and have always gotten good velocity out of it, but not always the ES/SDs I wanted. I'm sure some of that can be lent to brass, etc.
