Loaded up some Sierra SPBT this morning. This Ruger has been very finicky but adding a grain of powder and seating out an addition .020 seems to have taken a 1 1/2" loaded to this.
That kind of success is what keeps us reloading :wink:!
I am always playing just a bit to see if I can get it just a little bit tighter :mrgreen:.
Thank you for the post with photos.
Nice shooting and a nice looking rifle.
Have you thought about trying CFE223 or maybe IMR8208XBR. Both were designed around the 223 and 308. Burn rate for 8208 is right around the same for Varget and 4064 but CFE is a little slower than R15.
