RHB:

Thanks for the link. I will email them and see if there is a distributor carrying them here. If they are available I can get some and do a comparative test between them, a Brenneke and Foster type slugs in my test media. Also that would provide a comparison with all the rifle calibers I've shot and posted elsewhere.

I should have asked before...What GAME are you shooting? Reason I ask is that if the game is small buck of some sort, probably even those RC4's would be fine, if available.

I'm sure Daryl will get involved here, but my recommendation of BP is that it may be safer to replace the smokeless charge with a volumetric charge of black and then work loads with roundball than it would be to merely replace a slug with a roundball. Changing compnenets in shotgun shells just willynilly can reslt in unpredictable and possibly very high pressures. Using BP might be safer.

As for a loading tool a cheap Lee tool would get you started. Maybe $40 US? I used to have one and it worked, tho it wouldn't hold up to thousands of rounds. However, for merely removing the existing slug and seating a RB, you could probably get away with a homemade inertia "bullet puller" and hand seat the wad and slug with a dowel.

Let's see what Daryl has to say!!
