[QUOTE="Old Rooster, post: 2700568, member: 108576"] Lefty7mmstw I got another shock lesson at 2:30 this am.No one makes 40 cal gas checks. I went to Cast Boolits forum (they spell it funny) and someone asked the question as to why no 40 cal gas checks. Several on the forum replied that you don't need gas checks on 40 S&W or 10 MM as it's below the threshold of leading if you size it correctly. I read for 1/2 and hour and all that shoot 40 S&W and 10 mm shoot cast bullets but size them at least .002 over slugging measurement. Zero leading with well over 400 rounds in a Glock 10mm but if I remember right he said he casts at 20- 22 Brinell hardness.Another said 15-18 on the Brinell scale.Some are using spray enamel paint as a coating and curing in an oven. I had an Accurate Mold picked out with gas check but I can't find gas checks anywhere so I'll buy my bullets from Rim Rock or Cast Performance and powder coat them to insure zero leading. [/QUOTE]
