Has anyone here given IMR 4166 a try in their 6mm ARC yet? I have this Savage axis that is building up copper more than I was hoping for. Suppose more to my point I am looking for input on the effectiveness of IMR 4166 vs CFE223 & others in terms of reducing copper?

Think I have heard good things about power pro  2000 in most every respect in the 6mm ARC only issue for me with this propellant is finding some.

Hodgdon has added Ramshot and Accurate powder data to their nifty online reloading data. Many thanks!

Currently have a maxim bcg that was bought when first building my rifle. It's a 6.5G.....i was going to get a spare bolt to have around and now they have a separate number for a 6ARC bolt?
  Same .136 head and type 2 so is it just for people who don't know the T2 grendel is what they need?

I use Quickload quite often, but the Filling/L.R. boggles my mind. My loads say they are over 100% filled, thus slightly compressed. I measured from the top of the neck to the powder and this is just not the case.The base of bullet would not even be touching at the depths I load them at for the bullet I am using in the program. Just odd. Anyone else out there measure this? What I do is take a drill bit with a collar and drop it down until it rest on the powder then move and secure the collar at the top of the neck. Then, just bring it to the outside of the case. Kinda simplistic way of measuring, but it works. Going to do look at the case dimension part of the program and see if I can refine it a little to exactly my fire-formed case, of course after the .002" shoulder set back.

I just got some 70gr Nosler Varmageddons for coyotes. Has anyone messed with VV-N133 with anything around this bullet weight? Is it worth messing with, or is it dependent on higher PPC pressures? Will it cause any issues cycling a rifle +1 on a 18" barrel?

I'm putting together an ARC using one of Rebby's 16" Liljas with a Mid length gas system and a non-adjustable Yankee Hill gas block. I don't know the gas port size. What weight buffer should I be using?
