Hi Dave
May or may not have been me making the recommendation for "Big Lube" bullets. Might also have been Dick Dastardly, a prime supplier of Big Lubes.
I am fairly certain you got your bullets from "Springfield Slim" from California. His Big Lube bullets are rather superb.
Since you have had some shoulder problems, I might also suggest, in line with Big Lube bullets you might give serious consideration to the lighter bullets Slim offers to reduce your recoil strain. The 175Gr and the 200Gr slim offers are superb. Glad to hear your back to playing.
