Neither of those, but I did buy a lb. of RL2000MR and tried it in several guns. In the 6 Dasher custom rifle
, it did not work well with 105 Bergers. I also have a Cooper 6BR; with Hornady 105 gr. and 30 gr. 2000, it shot one group of .355 Also tried it in a M700 22-250 with 55 gr. ballistic tips, and it did not work well. I have not spent a lot of time developing loads for any of these rifles. Need to run some ladder tests.
There was an article in Handloader about 2 months ago regarding this powder. Because it is so new, load data is hard to find, and Allient's web site is pretty pathetic.
