    Ruger .30 Cal

    Which would you rather have .30 Cal Old Model 3 screw or a .30 Cal New Model? Both are shooters only.

    Mine is an early 3 screw, very tight. I like the older Rugers, but the new model does offer the ability to use 32-20 cases, sized for 30 Carbine. My old model has the standard full length cylinder, all the way back to the recoil shield, so rimmed cases will not work.

    I put an XR3 grip frame on it, along with a steel ejector rod housing and a steel Micro rear sight. Runs away with the style trophy.

    I’ve considered the same thing.

    I prefer the 3-screw action because it doesn’t have a transfer bar.

    I’ve had a few problems with transfer bars. Mostly from them being to short. I’ve had some that impinged the firing pin below center and would wedge the firing pin up into the top of the firing pin hole causing drag and light strikes. Mostly this happens when the sear engagement is shortened to get rid of trigger creep. The trigger no longer moves enough to fully raise the transfer bar. But I’ve had one that was that way from the factory.

    The 3-screw action makes me smile when I hear the 4 clicks. This is emotional but I like it.

    The new model can use 32-20 brass fire-formed as Nueces points out. So that gives you 2 options on hard to come by brass.

    The best would be to fit a New Model cylinder into a 3-screw frame.

    I opted to bypass 30 carbine with its tapered case and 0.308” boolits and go with 327 Federal Magnum. That’s worked out real good for me.

    But I don’t have a Blackhawk in 327. But I do have a convertible Blackhawk that’s 32-20/32 H&R. Never fired the 32 H&R cylinder because the 32-20 power level just seems more appropriate in the big Blackhawk.

    So I get why that level of power with a 0.308” boolit in a Blackhawk is desirable.
    To answer your question though, I’d choose the 3-screw……unless I found a good deal on a New Model first.

    Problem is they have the same old twist rate for the 110 grain round nose bullets. The Contenders in 30 Carbine have a 1-10 twist and will shoot heavier bullets with good accuracy. However, it head spaces on the case mouth and grows in length with any increase in pressure. It works, but.....kinda deal.

    I wouldn't buy either one. I'd buy one in 327 Federal.

    Yep, we shot the new model in cowboy matches with 32-20 and a .310 diameter lead bullet. Currently 32-20 brass and ammo is very hard to find for a reasonable amount.

    I have both, an unmodified 3-screw and a New Model. The 3-screw definitely cocks smoother, but the New Model has a better trigger pull.

    I have a New Model in 30 Carbine that I purchased new in 1990, I sent it to Doug Trunbull in the early 90's to have the frame color case hardened. Also put a Colt style ejector rod & assy and a SBH grip frame on it. Turned out really nice.

    Both of mine are New Models. I like being able to use .32-20 brass as identification for milder loads and .30 Carbine cases for full snort stuff. The two most accurate revolvers I own. The cut-down which I got cheap off GunBroker 5-1/2" gives up about 80 fps with factory ammo compared to the original 7-1/2" length, but is much handier to carry. Approximates .327 Federal with factory .30 Carbine, and .32 H&R Magnum with .32-20s.

    I'll put in 2c worth, and don't take this the wrong way, I am not knocking the gun or the caliber, but across the board, the 30 carbine BH cylinders are dimensionally the worst of any of Ruger's production. Badly egged throats, belled throats, wormed throats, tool marks, I am merely talking from my own experience honing these cylinders to straighten up the throats and size them for use with cast. The throats in these cylinders are fairly long, and they need a LOT of work to bring them to a uniform state, but the improvement is equally as dramatic.

    If you have a factory stock 30 carbine BH and you think it shoots good now, all I can say is you ain't seen nothing yet... Typical stock from Ruger throats in these run .309" on average.
    Got a .22 .30 .32 .357 .38 .40 .41 .44 .45 .480 or .500 S&W cylinder that needs throats honed? 9mm, 10mm/40S&W, 45 ACP pistol barrel that won't "plunk" your handloads? 480 Ruger or 475 Linebaugh cylinder that needs the "step" reamed to 6° 30min chamfer?

    For my buddies OM I sold him a small diameter 3118 (Lyman 32-20) that was dropping them about .310. Too small for my colts chambered in 32-20. I later found that mold that dropped them at .312-313. He is firing a moderate load of unique or 700X. Firing a full power 30 carbine in a 7 1/2” Blackhawk is the loudest handgun I have ever fired.

    The 30 Carbine Ruger is truly ONE of the loudest guns I have ever shot....the other being a 22 Jet 6".
    But 3 screw is the best.

    Every time the 30 carbine revolver is discussed, how loud it is always comes up!

    That's because of how loud it is. Truly astounding.
