Re: Restocking a Paradox

I just spoked to Paul Roberts of London here today regarding my own S&B gun. He only knew of a very very few paradox guns that actually shot well. Most them he have had his hands on to, wheren`t accurate at all. He knew only of one paradoxgun for sure that shot well, which belonged to an American, who had experimented a lot, to get it to a useful shooting. He had been at the Lancasters here today, and had spoked with them regarding the ovalbored guns..most guns with oval bore lost accuracy after a few hundred shots or sometimes even less.

What I see here on this thread here looks very promising.




I can see where that statement comes from. There are just so many variables it is tough to get the right load combination. The variables are powder, charge, wadding, cases, primers, and bullet weight, alloy, shape, and diameter. Don't forget condition of the gun too.

I just checked my notes and counted 80 different loads that were tested (the average was 6 rounds per combination = alot of shooting and testing). More than a few produced OK groups at 50 yards, but when fired at 100, they would not "group", in fact, they often would not show up on the target! I stopped at the first load that would stay in a 6" bull at 100 yards. That was my requirement, because Evans is a respected maker, so I figured if it had a 100 yard leaf, it must have been accurate @ 100 yards.

If you approach the B&S challenge with the realization that the whole system (paradox) is some sort of compromise when compared to either a game gun or double rifle you will be ready for the challange. I can hardly speculate why a certain slug/wad/alloy/case/primer/powder/diameter works. It must be some sort of Voodoo. Here are my notes for the winning load combination (I am only changing the charge of Blue Dot @100yrds):


Blue Dot:

36 grains - 1,125 fps, Pizza pie size groups......

35 grains - 1,090 fps, Hubcap size groups

34 grains - 1,070 fps, Winner!

Normal reloaders are talking about getting from 1.25" groups to MOA or subMOA groups. Here, if you are off by a grain, you are done and might pass on a really close load. It is just crazy.

If you have a regular Holland (BP or 24-30 grain cordite) follow Sherman Bell's loading methods in DGJ and let me know if it is that easy.
