    All the moulds you have for it?

    All of my Marlins (30-30, 35 Rem, and 45-70) have micro-groove barrels, and I shoot mostly cast boolets, very well indeed. I never realized there was supposed to be a problem with microgroove barrels until I started reading about the subject in a gunrag about the time cowboy shooting came into vogue. Ever since, people have been asking if it's possible to shoot cast boolets in microgroove barrels. Pretty much everyone who posts on this websight would seem to think so, and do. Mold yourself some boolets and have some fun.

    Size to throat diameter.

    Shoot the longest bullet you can cycle. Gives you the most bearing surface for rifling "bite" on the bullet.
