Adapting revolver load data for usage in a single-shot.

[Munk]

I don't know Munk, nor do I judge him. Most folks I talk to who shoot 454 talk about how heavy they can shoot. Though I'd be inclined to agree with you about 460. I figured I'd give him the benefit of the doubt and assume he would want to shoot whatever was most accurate regardless of speed and terminal performance.

The reason for my post is because I shoot a 1 in 16 and haven't been able to stabilize plain base bullets in the 350 grain +/- range. And the light bullets shoot with large groups. In my gun. All the while the X-frame shoots them like a dream.

It may be a different story with the ultra heavies. I haven't tested them in an X-frame yet. But my bagged groups (long bullet, 1:16 twist) posted in the pistol forum had everyone assuming I was shooting in a mechanical rest and subjecting me to disbelief and ridicule. And I'm just getting warmed up!

So I thought I might save Munk the trouble of shooting thousands of 300 grain bullets trying to make them work, and just shooting a few hundred. Whether he can get them to shoot or not is up to him!

I thought the X-Frame had gain-twist rifling that actually got faster in twist as it progresses down the barrel?

I'm going with the 240grn XTP Magnums because they're built with "magnum" speeds in mind, and they actually cost less than the regular 240s at some places. (and FAR cheaper than the FTX).

I don't feel the need to increase my costs for loading just yet by stepping up in mass. I intend to start at the lowest loading for the 240 because that's what's listed as accurate. So for now, it's just fun and target blasting.

Once I have a better feel for the gun and its performance, I'll probably start stepping up in mass and/or speed.

Once I scrape some disposable money together again, I'll get a chrony, and a .452 lee sizing die, and start resizing some of the mid-to-heavy weight .458 bullets and experimenting. I'd like to see if I can expand the list of potential loads for the .460 s&w beyond the paltry selection available.

I'm in the bay area. Are you a local to me?

The X-frame is gain twist, I'm told from 100 to 20. So our pistols are a faster twist than any part of the X frame barrel. My conclusion after thousands of rounds? Big and slow is the way to go.

very much not. I'm down on the edge of the I.E.

It'll also be a while before I can report on any of my earliest loadings. My gun is still in jail, and I'm going to be buying/ordering my supplies over the next few days.

Too bad, that makes sharing more difficult. Ultimately, I can recommend something that worked WONDERS in my 1 in 16 twist barrel. Especially compared to what conventional wisdom says should be about right. Anyways, I was blown away by real world performance (on paper) of 200 grains at 2400 fps vs 500 grains at ~1000 fps. And with respect to theoretical performance on game, 200 grain bullets aren't even on the radar anymore.
