Angry 460 load data

Hey guys! I'm working out of state, and just ordered a new 460 with 7.5" barrel that should arrive when I get back in town this Thursday. I ordered some dies and 240 grain CUP bullets, now I'm wondering if anyone has some moderate load data to use with 2400? This is the only powder that I'm sure I have at home when I get there. Looking to make some loads to get use to the gun, and will probably pick up some other powder when I get back to town, just don't know what I'll be able to find. I appreciate the help!

Peter

Alliant manual shows 31.0 gr as max for 250gr Speer GDHP; 45 Colt load for same weight is 15.4 gr - so any load in that range (15.4-31) should technically work. Also standard disclaimer applies - do your due diligence to double check yada yada.

Make sure your bullets are rated for the speed and pressure you intend to use them at. Typical .451-.452 bullets meant for 45 ACP and such are not suited for 460 use at 460 pressures and velocities even what would be moderate loads.

If you will provide actual bullet information I will provide you starting load information for 2400.

That is very bad advice!


A 460 and a 45 Colt are not the same cartridge and the load data for each is totally different.


Your "range" is not correct!

I’m aware they are different cartridges, 460 shoots fine everything from 45 schofield to 460 with 45lc and 454 casull inbetween. Might be not optimal small charge in bigger case but I don’t see danger in it.

Edited to clarify: I was looking at it as using 38SP data in 357Mag case.

I'm sorry, I thought I had that. I will be using the Hornady 240 grain XTP MAG bullets designed for the 460. I know that they typically 45 acp bullet wont hold up, but I do appreciate the warning!

Alliant 2400 data for a 250gr GDHP is maxed at 26gr for a 454 Casull. As another person mentioned, it's 31grs for the same bullet in a S&W 460.

It may be a little dirty with 26gr but it would be a good start charge. The 240gr XTP Magnum bullet shank may be different than than 250gr GDHP. I do know the 250gr GDHP seats deeper than a 250gr XTP with the .45 Colt.

Pete--- You might want to look at Speer #12 or 14 Loading Manuals.

They both have reduced loads in 460S&W. Also an old trick some loaders

use in reduced loads is some type of filler to reduce the voids in bigger ctgs.

This is/was used when subbing smokeless for black powder. Notably in 45-70..

btw... ruggy is the ''460 guru''.. l have followed his advice for years on my 460 PC

There is no "analogy" between the 38 special/357 mag and the 45 colt and 460 magnum

Just look at the difference in length.

Between the 38 and 357 there is 3.7 mm in length difference
between the 45 colt and 460 mag there is 13.4mm

You can not just guess or extrapolate a minimum charge anymore than a maximum charge

Ballistics are based on many many thing, especially case volume.

How much load data have you seen with a 15.0 grain variance between min and max data??
Some SW 460mags have a very long 8" barrel will and tiny charge of a very slow powder make it out the end of the barrel.


The OP needs to look at some manuals or Alliants load data, not get it from a forum.

The best advise given here is to buy a loading book and do your own research. Getting reloading recipes from an Internet forum may very well work out but in this case, the information provider did you no favor. Developing your own loads for your gun and your needs is part of the joy of owning your gun. If you are too busy and don’t have time, buy factory ammo.

With 240 XTP MAG using 2400 and bullet crimped in cannelure start at 80% case fill or 33.4 grains and work up. 37.4 grains will be typical commercial type load.

Guys don't use 45 colt data in 460 case, with most jacketed bullets you may experience squib loads.

I appreciate the info Ruggy! Like I said in my opening post, I'm working outta town, and will be in town for a short time. I do have manuals, and I have sent and email to Allient powders, still waiting to hear back just looking for some direction. I appreciate all the help guys.

I will add it here again for those new to reloading the 460.

Extraction is the best guide to operating under the the design pressure of this cartridge.

Do your load development with clean chambers and extraction should never be sticky unless you are near over pressure condition.

The max load data you see printed is not an absolute but a guide line. The tolerances of firearms vary widely. I have several 460s with tight throats and max loads are 2 full grains lower (depending on powder) than the average in my collection.

Always work your way up.

be safe and good luck

^^^More words of wisdom from Ruggy, coulda been me that wrote that......

I too stop and back off when I get sticky extraction(sometimes doesn't take much of a charge increase to go from cases falling out, to having to drive them out with a dowel), and my P.C. Compensated Hunter has tight throats, so most of my max loads are more "middle of the road" according to the books. Even many commercial reloaders backed off a tad since the inception of the .460 to ease with extraction. While max pressure is 65,000 psi, most load to about 56,000.
