I'm sure my newb questions have been answered here many times before, but after spending a bunch of time with the search feature, I'm still coming up short on answers.
I've been casting for CF rifle and pistol for some time, but just picked up my first ML, and am looking for some help picking an appropriate mould. I found a TC Impact in like-new condition for $175. I realize this is an entry-level ML, but it seemed like a good place to start without spending a bunch of $$. Twist is 1:28. From what I've been reading, this twist is suited for shooting saboted bullets, but not-so-much cast. What I'm getting so far is that I need a cast boolit big, heavy, and relatively slow. Is that correct? If so, what mould would you recommend?
Also, can I expect any success shooting round balls in this barrel?
I don't really want to get into PP right now. Too many new things all at once. Reading about 'volumetric grains' was bad enough... I've seen some ML projectiles sitting on the shelves that look like cast boolits with filled lube grooves like I'm used to working with. When casting for ML, can you run them through the lubesizer like other boolits? If so, are there special considerations for the lube, or is my normal rifle boolit lube OK?
Thanks,
Chris
