I need advice on how to build proficiency with a heavy-recoiling rifle.
As background, I reliably shoot sub-MOA with mild-recoiling (.223 to .270) rifles, on bench and bags, with my handholds. I can use a hand on the forend or free-forearm techniques successfully with this level of recoil.
I bought an M-70 Alaskan in 375 H&H specifically to learn heavy-recoil. From the bench, shooting heavy loads (270gr LRX or 270gr Speer SP) I find that group stringing is exactly correlated to my forend control technique. If I hasty sling on the bench, the group strings up and right (directly opposite the sling). If I use an unslung hand on the forearm and pull straight down, stringing is vertical. This is perfectly repeatable. The stringing is 2-3MOA, and group dispersion normal to the direction of stringing is typically <1MOA. I'm not flinching, I've checked.
With mild-recoiling loads (ie 350gr SMK, Sierra starting data), I can print sub-MOA groups. The stringing is definitely related to the heavy degree of recoil.
I conclude that my technique is failing to consistently control the first millisecond of movement via muscle tension (left arm and shoulder). My question is: what techniques should I be practicing, and what books should I be reading to improve this?
I've read a couple articles by Nathan Foster (Hold That Forend); is his
Practical Guide To Long Range Shooting worth the cost? What else should I be reading?
