Quick Load - BLC2 with Nosler 55g B-tips (223 Rem)

[AzDak42]

As the title implies, I'd like to use up my stock of BLC2 powder with a huge batch of blem b-tips that should be showing up. Can anyone show me the quickload data?

Sort of odd. Just about every reloading guide shows great fps with BLC2, and nosler doesn't use it for any of their loads...

Much obliged,

One trick I use when loading 223.... especially with 55 grainers..... is I return to MilSpec MV.

As Per Ye Old GuideBook For Marines.... the muzzle velocity of ammo used in the M16A1 was 3250 fps.

I'm trying Alliant AR Comp since CFE 223 has gotten rare around here and I'm saving my BL-C(2) for my 308. Still need to get it thru a chrony.
