That sounds pretty decent Bruce.
Roberts said his favored wad for that was a felt wad cut from a desktop ink blotter.

That's good stuff Bruce. I have just started shooting a CPA semi-traditional bench gun with a breech seated elliptical PP bullet. It's a tight fit like Kurt recommends and needs a Weber seater to enter the bore. Results look promising so far, but I don't think I'm in danger of winning a match with it yet :-)
I also really like the Buffalo Arms moulds.
Chris.
RE: just took my own advice - bruce moulds - 11-28-2015
an interesting observation.
confetti was good as expected from the gaintwist barrel.
compared to the 45/2.4 with a straight twist barrel it was more totally cut into strips.
what is different in both barrels to when using fixed ammo is that the folded under the base bit was still joined to the fingers made by the rifling.
the bases of breech seated bullets do not have to pass over the transition as they do with fixed ammo.
possibly this is where they are removed.
the 40/72 has a 7 degree transition, and the 2.4 has a 45 degree.
could this be part of the reason why breech seated shows superior accuracy?
keep safe,
bruce.

I can see where breech seated bullets wouldn't expand as much as the fixed ammunition, but I'm not sure that expansion is all that devastating. After all grease groove bullets do it all the time, as do jacketed bullets.
