So I'm still pretty new to casting. I have a RCBS 45-200-SWC mold with RCBS handles that I've been using to cast for bullseye shooting, probably cast about 3000 with this mold so far. Just got my new Magma 45-180-SWC-BB mold drilled for the RCBS handles which I intended to use my existing handles. I got the first set screw out with some resistance but the second was being a bear, it started twisting my cheapo folding set of allen wrenches.
So I sprayed the set screw down with some PB blaster to try and loosen up the set screw, I broke out the Bonhus US made wrenches which will take a beating. I still couldn't get it to budge and was at risk of damaging the wrench. So then I heated the mold on my natural gas burner for 10 minutes and the screw STILL wouldn't budge, at this point I damaged the allen wrench, good thing Bondus replaces them free of charge.
Now I'm stuck leaving the handles on the 200 grain mold and buying another $40 set for my new mold. It was either that or start drilling on the mold then trying to re-tap it with a larger size with possibly bad results.
Long story short I'm going to be putting some of my choke tube anti-seize lube on my set screws on the new mold.
