Super Redhawk 10mm Magnum...

So, I finally got this gun going. Has been an ordeal, but worth it in the end.

Just a basic SRH 7.5" in 10mm Auto. I sent it to Gary and after a few plan changes it was rechambered to 10mm Magnum.

As I've posted before, I have switched over and now only use TK Moon Clips. These hold the 40 S&W, 10mm and 10mm Magnum very close to the recoil shield.

Today, I put on some Hogue Grips and mounted a Barska 2x Scope on the gun. I'll take some heat for that choice. But, they were previously marketed as the Simmons 2x and I've yet to kill one. The sight picture is excellent.

First I tried factory 10mm. Groups surprised me and stayed around 1.25". But, 10mm Magnum was much better.

I loaded several different cast bullets, all sizes .401". The first group put five into one ragged hole. The last one was out just a touch, so group ended about 5/8".

I tried several bullets and powders. All stayed 1" or under at 25 yards.

The long cylinder of the SRH allowed me to seat bullets out for more powder capacity. I easily pushed the 200s to 1600 fps. Part of this is due to Gary's Guys setting the barrel gap very tight.

I'm going to try the same loads at 75 yards. I'll update here.

For now, I'll say the 40s are the most accurate over 32 Caliber Revolvers I've tested.

Not all the really great stuff makes it to reference books. This way I always have it available for projects like this one.

But, thanks for posting it...

Huey, what is the cylinder to recoil avg. gap?

I have a custom GP100 in 10mm and wondered if the Brownell's Clips would work on the 10 Mag. Not that I want to hot it up, mine's a 6-shot and the walls are thin. From what you say I'm better off just leaving it alone and seating long. Accuracy is great with .40 or 10mm. I made (6) rounds, only, of 10mm Auto Rim (so to speak - from .30-30 cases) but had to headspace off the case mouth so the rims were only good for extraction with no clips. The rims had to be turned to minimal to clear the pawl gear.

It's about .002" on mine with Starline Brass...

I think yours is a custom. If it has the same clearance as my factory GP 10mm I can send you a TK Moon Clip.

I like it a bit more sloppy. Man that is snug.

I've about talked myself out of it. I will more than likely rent a reamer from Fred Zelgin at 4-D and hog out my SP101 to .327 Federal. That makes more sense.

I sent my GP100 off to a reputable guy, he took a while, almost 2 yrs. His work was good but I'm not really wired to send and forget. Too much happens in my life and I enjoy the anticipation, yrs. and I DO forget it. He does not do them anymore. The guy doing his reboring died!
