460 S&W mag

[Little Jim]

Dose any body out there have any exp. with the 460 S&W mag. I am a newbe here and would greatful for any help that I can get. 275-350 gr is what I am thinking with a gas check.

Thanks Little Jim

Some Options:

Gas Checked .452 Commercial Molds:

-Lee gas check 452-300-RF
Weight with Wheel Weights= 320grains
pro: huge flat meplat great for hunting
con: insufficient crimp groove can lead to bullet jump

-Lyman gas check 452651 325 grain round nose flat point
weight is around 335 grains if memory serves me right
pro: better two crimp groove design than the Lee bullet
con: non than come to mind

-RCBS gas check 300 SWC weight is a touch over 300 grains
Pro: good crimp groove and more accurate than the other two at long ranges
Con: non that comes to mind

-purchase a custom mold from the various mold makers etc.


-Other options for heavier bullets are to use a 45 caliber rifle commercial mold and size your bullets down to .452 etc.

thanks rob I will look at the RCBS. A 300 gr is right were I think that I want to be.

I dont know what you are wanting to do? Remember you cant drive a cast at 2000fps. the Lyman452651 Is a good one if you want a heavy flat nose or can be HPed for a good hunting boolit. There is guy on here that does the hps so you can have both.
The 255gr cg is a good one and it dont have recoil that the 300s do . Will suggest you leave the comp off or get some Kroil to soak the lead off. They do build up fast

Something stinks like a barn where they keep male cattle.

[shotman]

girly do you shoot a 460?? it will melt the lead in a 8in barrel, jackets are a hard clean. It aint no rifle

[RobS]

Well darn near 2,000 fps anyway and with a plain base according to Hodgdon:

325 GR. CPB LFN PB Winchester 296 .452" 2.200"
38.0g 1810 fps 45,300 PSI
42.0g 1953 fps 54,900 PSI

It could definately be done with a hard alloyed 300 grainer with a GC.

The facts are there

Thanks Shotman,you like the lyman more. I just oreded the RCBS 300 gr gc yesterday that ROBS talked about. I did not want to start world war five here just looking for some ideas.If that dose not work out I will look at the lyman. Haveing said this what do you think of 2400 for this load?
Iam shooting the 240gr hornady now and 296, but have had good sucess with the 2400 and my boolits in the 357 and 44 all GC and running hot.

[shotman]

2400 is good, meters well. I just didnt see the point to drive a hand gun at 2000fps with cast. The comp leads bad enough at around 1100/ 1200. I was useing the 300gr with blue dot and was doing ok for me at 50 to 75 yds

[RobS]

Now I agree with shotman regarding driving 300 grain bullets to 2000 fps from a hand cannon as it would darn near tear your hand off. I shoot a 454 casull which also operates at those high end pressures, but do not enjoy shooting large bullets at the bone crushing velocities, or at least not very often. It is nice to have a firearm where you have the option though if needed. I too used blue dot for loads around 1,200 to 1,300 fps with the RCBS 300gr SWC GC and recoil was less than that of the slower powders in that general velocity range. 2400 will work really well too as does #9 and for the higher velocity rounds at safe pressures Winchester 296 or the equivalent Hodgdon H-110.

-Other options for heavier bullets are to use a 45 caliber rifle commercial mold and size your bullets down to .452 etc. Yep, I'd be thinking of the 330 gr 457122 HP "Gould" squeezed down to .452-4"...(What I'm doing in .45 Ruger BH) That's a classic old .45 cal game killer, at 460 velocities it should be explosive with right alloy....:wink:

[RobS]

I use an RCBS 45-325-FN-U plain base rifle bullet in my casull and at 345 grains it's a thumper on both ends. I was lucky though to find a member here who sold the mold to me and it cast undersized bullets (.457 ish). Since my revolver cylinders are .4545 and my groove diameter of my barrel is .452 it was an easy size down to .454.

[Little Jim]

Is that a gc bootit (?) I would think the gas check would work better at such high presure the 460 puts out (leading ect). If the RCBS dose not work out for me I think I might try a custom job with GC at 454 dia. When I had my gun smith slug the barrel it was a heavy 452 and a 453 would be good, but try the 452 first before you spend the big bucks. Two boxes of j bullets from hornady =one RCBS or LYMAN mold and factory loads are way too much. I want cut the cost so I can shoot it more,before I take it out in the woods.Not to mention I need to back it down some so I can shoot more.

[RobS]

The RCBS 45-325-FN-U is a plain base rifle bullet and if cast hard it can do 1200 fps (probably more, but I don't enjoy shooting it then) with no leading. If you want a bit more velocity and prefer a GC then maybe look toward the RCBS 45-300-FN gas check rifle bullet mold. Lyman also makes 45 cal rifle molds although they are only single cavity molds where as the the two RCBS molds I mentioned can be had in a two cavity design. Since your barrel is a .452-.453 you may have better luck sizing down the 45-300-FN GC mold to .454 and have at it. This was actually my first choice for my revolver, but the nose is a bit too long for my lever action so I went with the 45-325-FN since it has a shorter nose.

Did you check your cylinder throats? If they are at .454ish then you would be good to go and I would work with .454 sized bullets. If the cylinder throats are .452 then it wouldn't be of any good to try a .454 bullet as it would only be swaggered down as it exits the cylinders. You may already know this, but I'm just trying to give you a little info in case you don't.
