Never gets old

You should be proud Rick, you got me started on looking at all this more carefully. To started with the 44 mag and now has trickled down to my other revolvers.
No more just grabbing a set diameter for revolvers, I will be doing some measuring and thinking first.

Square B? Did you mean B square? If so, I can't find any of them anywhere.
I see a Weaver no drill mount available, I may look at it. Recoil certainly won't be an issue.
I have an MP 311410 mould on the way. I have lots of 30 carbine brass I can use but I will also try the 32-20 brass. I have plenty of that too.

The Weaver mount is the same as the B square. Rick, recently bought one, for his BH and it looks exactly the same as the old B square on mine. BTW, my BH is a 45 L.C. and it has handled Ruger only loads for many years with out shifting.

If it can hold on a 45 Colt it will hold on a 30 carbine.
That is very helpful info, thanks winelover.

21.5 gr of H110 in Starline cases lit by a Fed LP std primer. Bullet is an MP 44/444 305 HP. Gator checks and some home brew lube that I can't tell what it is.
Meet me at the range someday and you can shoot it. Velocity is 1325-1350 fps.

I'd love to shoot it sometime.
I'm surprised your not using plain base boolits.

The mould was made as a GC so I went with it. It does double duty in the 444 Marlin so the check isn't all bad.

Magnum handguns have always interested me.
Not so much with magnum rifles. My shoulder is beat up enough from working.
What kind of rest are you using with the revolvers?

A simple bunny ear rear bag sitting on a hunk of wood large enough to get it to an elevation I like.
I have, at times, used my Sinclair front rest turned backwards so the third leg goes forward giving a place for the grip of the revolver.

Try shooting at one of those targets I made. The green lines help you line up the sights more consistently.

Glad to see you use the fed 150. Exact same load I use for 300 gr and up to 320 but I use 296.
I found a difference long ago between it and H110 where most guns like 296 while a RH loved H110. Hodgdon got a batch with a different burn rate then WW, same powder but it was sorted to each spec.
Now the S&W 29's. They can't take recoil from heavy boolits, internal parts geometry has too much inertia. They are OK with pressure and we figured 265 gr was top.
The big reason they never were in the winners circle is the grip angle. I had 5 or 6 over the years and I could shoot 1/2" groups at 50 meters but if I put the gun down, the next 1/2" group would be 10" from the first. Darn thing felt the same in my hand and I could center the first 5 chickens at IHMSA, put the gun down for target setters, pick it up and miss the next 5. I have trouble with the RH and a Bisley too. The SRH just needs held firm.
First thing that happens with recoil is the pin in the center of the cylinder that unlocks the cylinder will peen on the end so the gun gets hard to open.
Then the cylinder stop can drop and unlock the cylinder and hammer bounce can double strike a primer or out on the brass. Some cylinders turned back to the previously fired one so your next pull is a "click." If there is a live round there, the gun can double. The X frame in .500 was doing that. The stop spring was too weak and I believe S&W cured it.
They blamed it on shooter error with a double trigger pull. Tests we did with an empty, primed case in first under the hammer would fire when the next chamber went off. The cylinder turns backwards from rifling torque.
Hammer bounce is real on all revolvers and many rifles too. We have photos of hammers near full cock at ignition caused by internal pressure against the primer that kicks the firing pin and hammer back.
The S&W is a very easy gun to fix to stop the funny stuff.

they'll fit.
they won't fit if you add another .0011 to each side, take that down to .008 and they fit again.

my problem was with the 30 carbine brass I got a bunch of milsurp in the spam can stuff that shoots just fine as is but the length of the cases is all over the place.
trimming makes it too short to head space properly and fire reliably.
