I have two repeat customers that love two projectiles for their guns:
www.mp-molds.com
accuratemolds.com
Problem is, both of these slugs do not consistently fill out past .002" of spec. I have other moulds that do not have this issue.
The .252 is being shot out of a K1. Variance is .252" - .2535". The owner is using silicone grease to keep them in the mag!
The .455 is having the same problem in a Rattler. However, it feeds the slugs reliably.
So my intent is to pilot these slugs with the same customers, hoping to add .001" diameter to each side, thus fixing the consistency issue.
If I am successful, and the slugs fit reliably with the same accuracy or better, I will offer this service to my entire product line.
So far I'm starting with red powder coat. I've read that turquoise and green are other good colors. I've done the homework online, but no question there is a learning curve in the real world.
Seems like the only other airgun slug maker I know of that offers powder coating for airgun slugs is ZAN and AEA. ZAN priced their hyper line 43% above traditional slugs.
We'll see how it goes in the coming weeks.
