I love my .220 Model 70 Heavy. I use RL15 and 50 vmax at darn close to 4000fps, and have shot 40s around 4300. Give it the gas- steel is cheap.
Am currently messing with H414 to see what happens, and hopefully to standarize my powder stores. Got really great acuracy when the rifle was new with IMR4350, but I wanted to go full throttle and RL15 did it...
