Finally had some time...and most importantly...the AMBITION to get set up and give this mold a try. I have had issues in the past with the brass H&G #68 with bases not filling out.
I read a few posts stating one needs to run BRASS on the HOT side.... so got a hot plate to warm the molds and turned up the pot to 850. by the 3rd pour I had a few good slugs..by the fifth pour they were ALL nice.
If I let the temp drop too much ; bases would round out not fill out and come out FLAT. I settled on 850 ...Hot enough?
With basically straight WW's and a bit of tin...I got a consistent 285 grs out of the slugs. Exactly what I wanted for a plinking bullet in the .454 Casull and hotter .45 Colt loads in my FA M-83.
Any other hints on casting with the MIHA molds?? Can I go TOO hot??
