Alliant 2000MR and 4000MR in-stock at Widener's

I personally have shot 2000MR with temps in the 80s, havent had any issues, my first 600BR comp, the temps were in the high 80s and humidity to match, was shooting 42.5grs 4000MR in my 6mmREM, very consistent 7/8th moa groups from 100-600yds. Barrel was very very hot right after I did the 3 sighters. No issues.
 
Typical group I get with 4000MR in my 6mmREM out to 300yds.
