First time going to load these in my .556 RPR. Anyone using them with TAC. What coal is giving you good results

I buy the 77 gr Sierra,, BTHP. BL-c2, CFE 223, IMR 4166, 748. These shoot excellent in my AR 556.

I buy the Sierra bullets from their outlet store. In Sedalia, MO. That is the powders I use. Mini Ranch shoots these heavy bullets well too.

I'm looking for info loading with TAC

I wouldn't worry about what anyone else loads.... what works great in their rifle may or may not shoot worth a darn in yours. Work up your own loads trying different powder charges.

I thought you were asking what powders others used. I'm sorry.

Sierra has data for that combination. Give them a call.

The answer they gave me was use the 77 grain matchking data

Sierra used to quote their data to you over the phone.
