Re: 75 grain hornady 223 varget loads
DAFAR,
I've developed a load in a similar rifle (Rock River 20", 1-8 twist varmint rifle). I've been using LC brass, Varget, Win SR primers, and have tried Sierra 77gr, Nosler 77gr, and Hornady 75gr bullets.
The Hornady's and Nosler's were about a tie in the accuracy department, with the Sierra's falling WAY behind.
My most accurate charge weight was 24.5gr of Varget, but be forewarned this was about as hot as I'd run them. At 25.0gr Varget I was backing out primers. This load is running between 1/2 to 3/4 MOA. My velocity is 2675fps. Seating depth 2.255".
