mikeor70 Posted November 5, 2017 Share Posted November 5, 2017 24.6gr of R15 and 77gr SMK going 2680 working good for me in 18" Wylde. LC brass and WSR primers. I have been keeping OAL at 2.26 +/- .005 as its already a bit compressed. Link to comment Share on other sites More sharing options...
GJGary Posted November 5, 2017 Share Posted November 5, 2017 WOA 18" barrel likes the 77smk with 23.8gr of 8208 2.260oal. My 5r 20" barrel likes 77smk with 23.4gr of 8208 2.260oal. 77smk and 75 Hornady are interchangeable in those 2 barrels Link to comment Share on other sites More sharing options...
