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

[Munk]

Can load data for a revolver be modified to account for a longer, fixed, barrel.

I ask specifically, because I'm going to be reloading .460s&w for a 15" T/C encore, but most data I find is for a much shorter barrel on a revolver.

From what I understand barrel length shouldn't effect pressure much. They should shoot fine just higher velocity.

Use the same data.

The Contender usually has a separate set of load data. I guess they haven't published it for the 460 yet?

I've seen the "one book one caliber" guides for contenders and encores, but most of the data stops at the .454 casull, and I don't want to run such a small round, even though I can if I got the urge.

some cursory searches online have yielded very little encore-specific load data for the .460s&w.

Loaddata.com has some data for the .460 in a 15" T/C. It says its from the Lyman Reloading Manual 49th Edition.

Same data. You'll just typically see more velocity out of the longer T/C barrel than a typical revolver.

Nice. Looke like i'll be getting some H-110, and reading the book somewhere to get the charge weights for the 240grain Hornady Magnum XTPs.

Or go here- http://specialtypistols.infopop.cc/eve/forums lots of good info.

What's the twist rate on the encores?

Eabco has a pretty solid list of factory twist rates here.

My .460 appears to be 1:16.

Lymans 49 has a tc section with 460 loads and the data looks the same, at least for the 240 xtp you mentioned and highest velocity next to little gun.

I would bet dollars to donuts your gun will do better with long bullets (aka on the internet "heavy") as compared to short ones.

Yep, but most noobs to handgun hunting with 454 or 460 are enamored with speed, so much so that they miss out on better terminal performance.

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!
