Enabler here - 5" FA83 converted to 500 JRH by Jack Huntington. I really like the shorter barrels. Due to balance and other age related issues I don't hunt anymore, so I don't need a big bore but am reluctant to sell any. Also have 6" 454 and 475 LB (475 is left gun in my Avatar) Paul

My opinion is generally that the shorter the barrel the bigger the bore should be. Make it a 500 Wyoming, AE, or JRH, or a 475 Linebaugh. For grizzly defense I'd pick a double action all day long. Or perhaps alternately the shorter the barrel the lower the pressure?

I like the shorter 83. It is different from the 6". But in your instance I would consider going to 475 or 500. I like 400 grains at 1,000. The 500 WE brass is problematic but now available through Bengal on GunBroker.

The 500 WE brass is problematic but now available through Bengal on GunBroker. Good to know. Not central to this thread, but of interest nonetheless: does moving projectile diameter up to .475 or .500 improve terminal effect on game over .45 cal or .44 cal assuming penetration is complete pass-through? I have been pondering lately whether extra foot pounds of energy matter if pass through is attained and I suppose now I am wondering about bullet diameter as well. Cheers

Hey PotatoJudge, I forgot to ask you: what double actions do you like for grizzly defense? My current inventory consists of a S&W Mtn Gun .44Mag, Ruger Redhawk Bowen Kodiak .44Mag, and a stock Ruger Security Six .357Mag that my father carried in GA back in the day. Would love to hear what you like and use. Thank you, sir.

Here's some data. I believe several would agree fpe is not the best measure for big bore revolvers. TKO is likely a better measurement.

Would love to hear what you like and use. Thank you, sir. I don't live in bear country, but I have some guns that would fit the bill. A JRH Redhawk in 45 Colt that can be loaded to near 454 levels, a few S&W Model 69s just because I like the L frame over the N, a 396 Mountain Gun in 44 special that's great to carry but might take a back seat to the 69 in bear country, a 625 I can load with auto rim brass to match standard 45 Colt ballistics. I've deer hunted with my Security Six and like how they carry, but you'd have to be picky with the load in bear country. I think making hits with the right load is more important than the platform, and that means a load I can make quick hits with.

Or perhaps alternately the shorter the barrel the lower the pressure? ***** edk.... incorrect. Pressure peaks in the chamber or, depending on cartridge, powder, and bullet, very early in the bore. Bullet does not reach velocity until well after peak pressure. A couple of things to know about recoil characteristics:* Providing the same model revolver, with same load, a short barrel produces more rearward thrust. * Longer barrel has longer BARREL TIME, causing more muzzle whip, or rise.

If you can eliminate the brass problem the big bores will cover all the bases without having to go to maximum velocity just because of those big, monster bullets, they do the work load without beating you to death. It's a good feeling having a 45-50 caliber revolver on your hip or shoulder if you get in a jam all of a sudden & need major horsepower to save the day. You can always load down, loading up can sometimes cause a problem. I've never heard of anyone wishing they had a smaller gun if they suddenly got in a bad situation & had to shoot their way out of it.

Going a little further, when I first went to Africa in 2001 I took a FA 475 that I bought from Marion Baker, Wayne's wife. They lived on the Idaho side of the highway. They hadn't been out too long & brass was a little bit hard to come by but I managed to get my hands on 100, a bullet mould, etc & I was ready to dive into the world of big bores. That thing almost beat me to death. About 3 cylinders full a week was all I could stand, actually sit, using the Elmer Keith reclining position. Anymore than that & I would start working into a flinch. It was a brutal first lesson into the ultra big bores sixguns (five guns) I think I was shooting 400 gr bullets but can't remember. I had a 4X Leupld on top & the gun was amazing as far as accuracy but it took every bit of my concentration to shoot that gun 2-3 times a week. I shot one big Wart Hog with it & a Guiniea Fowl & my PH decided he had to have it, I was glad to leave it in Africa, along with a FA shoulder rig, extra ammo, etc & when I got back state side I sent dies, bullet mould, more brass, everything he needed to enjoy a gun I'll never buy again. For you guys that like them, I salute you, keep eating your Wheaties, raw meat & gun powder for breakfast & I'll stick with my proven 480, just an opinion. And yes, I could have loaded it down to 480 horsepower but dang, I was going to Africa, who wanted to load it down!!!!

Greetings Noble Enablers, I’ve been on a bit of an acquisition bender lately, >>SNIP<< Acquisition bender? I like it! :-)

Yessir, Gnappi. I should probably call it quits for a bit but the wheels keep turning. I got a CZ 75 D PCR for a sweet deal, then bid on a .44Mag Mountain Gun and got that for a decent deal, same with a Bisley .45 Colt, and same with a Sig Sauer P229 M11-A1…. Somehow the urge isn’t going away. Anyone know of a program to check myself into? At least to help control the cravings. Any advice appreciated. My name is Phil, I’m 37, and I’m addicted to firearms.

David Bradshaw The OP asked: "why go bigger bore when going shorter with the barrel?" Potatojudge replies: "My opinion is generally that the shorter the barrel the bigger the bore should be." As a rule of thumb I offered: "Or perhaps alternately the shorter the barrel the lower the pressure?" as another possible rule of thumb as generally bigger bore cartridges are loaded to lower pressures. The exit pressure (and thus report) of a 4" 45 Colt is far less disturbing than that of a 357 mag. There are exceptions to the rule thus make the case for shorter 45 Colts and longer 454s.
