175 grain CC Favorite .308 loads?

[andrewctillman]

I have been using 175 grain black Hills and Federal ammo in 20 inch Remington 40X with Badger Creek magazine conversion. Have alot of brass to reload. Id like to keep at 2620 fps I am getting now with the SMK's.

I am limited to 2.80 OCL because of the magazine feed.

I have RL15, Varget, 4895 and W748 on hand.

I have the current Nosler manual. Any suggestions?

I don't have a load worked up but maybe give Norma 203-B a try. They have load data on their website.
