yes the 480 ruger is great as is but...

can the 480 ruger puma be altered to feed a case that is .115" longer???

the cassul brass is 1.383". the 475 linebaugh brass is 1.4" that is .017" for the subtraction impared. soooo either the linebaugh brass could be shortened by .017" for a middle of the road compromise (lets call the compromise round the 475 lever linebaugh or 475 L&L. the L&L would be .098" or almost a tenth of an inch lnger...that is pretty significant in the handgun class world! ) or the puma might be altered to feed a case that is .017" longer

what do you think?
has it been done?

another alternative would be to load the bullet out of the 480 ruger to get linebaugh power but hey what fun would that be

thought it would be a good matching rifle for a 475 linebaugh wheel gun

I guess my big question would be 'what's the point'. You would spend a lot of money and gain nothing.

i think there is a significant diff. between the 480 ruger and the 475 linebaugh...

if i had a 475 linebaugh wheel gun i'd like a 475 linebaugh lever gun too. yes you could shoot both in the wheel gun but i think having the same loads in both is a significant advantage to some.

Easier and cheeper is to get a custom mold made with a long nose, so you can load the 480 to 475 powder capacities. I have such a mold for my 480, the nose is 0.51" from the canalure.

I'd be concerned that the 92 couldn't feed the longer rounds, and would hate to go the expense of the work to find that out.

Somewhere I have a picture of that bullet.

It's the 3rd from the left. Also shown l to r are 275 swc, 310 lfn, 400 XLFN and 460 WFN. The 460 is crimped in the front lube groove, as if it's seated to the canalure the gas check bulges the case Yup, that 460 is loooong bullet.

Even std 480 loads should be impressive from a 20" fixed breach barrel, I'm thinking 400 gr @ 1500 fps should be easy, and at most the linebaugh or long loaded 480 will do 1700. For the 460 grainer I'd figure 1300 for the 480, and at most 1500 w/ the linebaugh.

No there isn't.

lever gun rework always means $$$$$$$$$$$$

i'd rather have a 480 ruger rifle and pistol, anyway.

jeffe

thanks paul for proving my point...

an extra 200 fps with the larger dia. is the diff in power and affect of a 45-70. get 9 rounds of 475 linebaugh!!!

it is a trimmer lighter gun for ease of packing to boot.

we already know it can feed a longer case reliably soooo you are nothing if you just do the long loaded 480!

if you ream out to 475 linebaugh or the tad shorter version you will be out some dough...but that is why i am asking the gunsmithing gods at a.r.

can someone with a 480 ruger puma try cycling it at the 454 cassul oal???

Supposedly, this guy is the be-all, end-all stud with the Rossi Puma.

http://stevesgunz.com/

I've never used his services personally.

thanks analog peninsula...

steve said the 454 oal is the max as far as the length goes and to use the flat nose bullets with no lube grooves exposed.

soooooo...

according to steve it IS possible to do either a long cassul oal, a .017" shorter bullet in a 475 linebaugh case or a 1.383" brass version of the 475 linebaugh (475 L&L) i am sure though with some more expensive smithing the regular 475 could be worked to feed but i think a custom bullet like paul has is the ticket!
load em long and get an extra 200 fps!

paul...that third from the left would be great for the puma...see if they have some 480 pumas up there and see if it cycles

45-70 power and affect in a 92 with 9 rounds and all yer out is the cost of a custom bullet mold!

pretty good deal imho

these bear tooth bullets 420 gr bullets might be a good candidate with its 2 crimp groove options. 50 for $17

I need to cast up some lee 400 gr bullets, as they have a second canalure and can also be loaded long, though not as long as the custom mountain mold, and they are a plainbase bullet.

I haven't come across a 480 puma, though it would be interested to run some dummies through one. I did handle a 454 puma, and my impression was, this is a crude gun, and at $400 and change it was an over priced crude gun. So I never bothered to persue one in 480.

I did pick up a moison nagant with the thought that I'd make a 480 carbine out of it, despite being warned the magazine would be a major issue. Well, that's right, modding the nagant magazine would be a major issue, and a single shot bolt gun in 480 was of zero interest to me.

reading the gunblast article they seem to be o.k.

maybe that was the ugly duckling rifle that nobody wanted...

it would be a "working gun" and fer shure not a safe queen.

steve said that they are all a bit diff in oal cycling so try out a few for longest cycling.

i think with some of these dual canalure bullets WHY NOT try to get an extra 100 fps over reg factory 480 ruger ammo.

added bonus for me would be to use the same bullets in my soon to be 470 a.r.

I would think that most factory linebaugh rounds would be the same OAL as the casull. If not they couldn't be run through the freedom arms guns.

good point micdis!

i might need to find some factory 475 ammo to try to cycle in a puma

even with a tad of smithing it would be worth it but the long aol 480 ruger is a slam dunk.

from beartooth website....

"Very accurate bullet with huge meplat for astonishing performance on game! An EXTREME performer in all respects! Crimp length right for all revolvers including .480 Ruger"



so i guess these are good for the 475 linebaugh for the freedom arms using the top grove...

so maybe these loaded to the top crimp in 475 linebaugh would work in a puma pending a little reaming for longer case.

but an unaltered one HOPEFULLY will cycle with just crimping to the bottom and getting the same performance

either way impressive performance in a $400 gun and 9 rounds in the mag

Here's what the 275 swc, 310 LFN, 400 Lee, 400 XLFN and 460 WFN look like nekid

I've shot the 480 alot, and have shot a few 475's. Two reasons I don't load the 400's to 1350 fps. Number one is, the 1200 fps load is scary accurate in my SRH. Number two is, I've shot 475's, and while an extra 100-150 fps doesn't sound like much, the fealt recoil seems to be about doubled. I know my limitations in a handgun, and the 480 is it for me.
