W-748...better for me than 4198 & I like Rem 7-1/2 BR primers for this combo.I know back in it's heyday a lot of benchrest shooters got away from 4198 in the deuce because it doesn't run through a powder thrower well but other than that is there any reason not to use it in a 222 nowadays.
I guess what I'm asking is, powder throwing aside, is there anything that much better for the 222 (normal 50-55gn bullets) than 4198?
