Re: Seyfried on bullet grooves for Paradox guns

That bullet is giving consistent 4.5-6" groups at 100 from a Super Redhawk off the bench. Lots more testing to be done to see what can be done to make it shoot. At this point I view it as a test bed to explore the Paradox effect. I have already tried a few hollowpointed and some with grooves cu...

Re: Seyfried on bullet grooves for Paradox guns

I did better, about 2.5", with a 305 gr HP from MP moulds. It showed far less deformation but it also had a much deeper angle sided grease groove. It also had a much longer check shank. I have a few other bullets I want to try in time. What threw me most was the lead on the sides of the check. ...

Re: Seyfried on bullet grooves for Paradox guns

Posted more results from firing. Starting to really look like my biggest issue is having .432 throats and a .429 bore. Squeezing a bullet down .003 does bad things to the bullet, even worse with this design.

Re: Loverider in a revolver ?

Interesting results. I wonder how the reduced diameter nose bullets would do on paper. Does the nose really help guide the bullet straighter into the bore if it fits the throats snugly? I hope to do some similar testing before too long. I want to nose size my bullet to a better fit with the bore and...

Re: Enhancing Reclaimed Shot ?

Have you ever tried any of the alloys with small amounts of copper added? If so, did you see benefits.

Those are some might hard bullets you are shooting. How much tin?

I enjoy reading this stuff. Someone going outside the box and doing something new and unusual.

Re: S & W N-frame Project

It is worse than you think. Are your chambers actually just minimum length? Is your brass max length? Make an impact cast of the cylinder end and throats area and measure for yourself. I bet you have .025+ free space before even hitting that taper. Make an impact cast and do some measuring. What is ...

Re: S & W N-frame Project

The deformation on one side being more severe than the other is something I know well! I will be watching to see what you make for changes in bullet design. I wonder if a bore ride band at the start of the nose followed by a full diameter band wouldn't be a good idea. I really like the bore ride ban...

Re: S & W N-frame Project

Have you considered firing groups using only one of the chambers that does line up well? Compare it to one that doesn't and see if you get group size differences. I wonder if one group would form in a different location relative to POA? My Super Redhawk suffers from misaligned chambers as well. I di...
