Anyone have experience with these? With chamber pressures insufficient to cause any deformation, is exact barrel fit the best?
Thanks for the feedback! I think I found your website just yesterday and plan to order some of these from you. I have experience casting for PBs but none for Airguns.I'm sending these slugs out as samples to customers who order .30cal from me. The HP is 59gr, cup point is 61gr., and solid is 66gr. So far it's only been one customer, and I haven't received any feedback yet.
Save yourself the headache and slug your barrel. From what customers are telling me, the bare lead slug wins out vs. the power coated ones if powder coating isn't necessary. I only powder coat if the customer's barrel needs an extra .001 - .002 for a proper fit. It's rare so far, but it works when needed.
