I got notification that my 10” 327 federal barrel should be delivered tomorrow. It should be a .312” groove with 1/10” twist. I’m pretty jazzed about this. I have 2 revolvers but the thought of maybe shooting 200g bullets has me intrigued. I’m using a stock front sight and a Williams receiver sight. I just can’t get the hang of a scope on a handgun . The barrel is coming from Match Grade Machine. The gestation was four months.

That should be a sweet shooter for you. I have the original T/C 32-20 10" barrel and boy does it make a nice varmint shooter. With the Accurate 313120B at 120gr, it is a real puncher. With the Accurate 313110B at 110gr and its "Keith Type" profile it hits pretty hard too for a little 32. As you know, the T/C 32-20 has a .308 groove so one can use lightweight 308 bullets in it. Here is a video of that barrel shooting 110gr varmint bullets over a healthy dose of H110:

The Accurate bullets shoot cloverleaf groups out of that barrel, and mind you, I am running them at .312" through a .308" tube! Velocities are modest - not light speed. I have tried 170gr bullets at modest velocities but not 200gr bullets. The 200gr brethren take up so much case space.

Keep us up to speed and post some photos of your new tube!

 

 

 

With rifle in hand, I confidently go forth into the darkness.

Your 1:10 twist might stabalize the 200 grainers.  Decades ago I tried some 180 gr projectiles in a Ruger Blackhawk .30 Carbine.  That went as expected: bullets keyholed.  Twist was way too slow.

I’m hoping I can get them going fast enough. If not I’ll use the other 13 molds.

I like this bullet a lot. I can get over 1200 from the single seven.

My barrel showed up and it looks promising. The chamber is tight. I’m going to try sizing .312” . My existing loads are .314” to fit the Ruger cylinders. The pistol closes hard. When I extract unfired rounds a ring of lead is pushed against the case mouth. I’ll do some forensic study later. It looks like it’s going to be a shooter. The Williams peep works well. I need to watch the light conditions. It was getting late and I removed the sight disc to let more light through. Things got crisp then. I had a couple 1” groups but most were 3” at 50 yards. Took a few pops at 175 but that was a dream waiting to happen at this point. The extra length of barrel and lack of a cylinder gap makes me want a chronograph. I was shooting accurate’s 135 wide flat nosed bullet over H110 and a lighter loading of HS-6. The recoil is very close to what I remember of a mid-range 357 with 158’s. It’s a very pleasant and interesting firearm.

I have a 30 carbine 10 inch with a 1 in 10 twist , it shoots the 200 gr. cast bullets really well ,it has a generous throat that allows the bullet to be seat out as to not hinder the powder capacity and can get 1200 fps. with out any pressure sign using 2400 powder.
