Blue Dot has worked very well across a broad spectrum of cartridges and bullet weights and shotgun shells. It remains my mainstay.
Recent purchases of LongShot and IMR 800X have tipped the scales at $30 + per pound.
800X has been a good performer actually better than LongShot with heavier bullets and LongShot performs better than 800X with the lighter bullets from what I can tell.
I like LongShot in the 9x25Dillon cartridges but will start workups with 800X to compare.
I may get a chance to do load testing tomorrow a.m. and want to make up some test loads for my G20 tonight. I have a couple of lbs. of Blue Dot on my loading bench I use for my S&W 500 for practice rounds.
What do you recommend to be a good warm to hot load for a 165gr JHP using Blue Dot for my 10mm? I'll be using by new KKM 6" barrel. I was thinking of about 11-11.5 gr. of Blue Dot. My Gen 4 20 has their new dual spring RSA, it feels alot stiffer to rack that other stock RSAs.
