A good custom rifle builder on speed dial. I use Charlie Sisk of Sisk Rifles for all my unique and weird rifle projects because Sisk knows how to build a good shooting, dependable rifle from just about anything. Like the .416 SM2 rifle we put together which was a .300 WSM necked up to .416. Then there was the Rem. Model 788 chambered for the .25-35 that my son used to take his first deer. The last rifle project we worked together on was the Sisk CSR which is a tactically configured .308 that I used to whack an old mule deer buck at 329 yards. Every rifleman has to have a good rifle builder on speed dial. Check out Charlie’s book on Custom Rifles.
