Not actually for hunting, just as a companion sidearm while hunting. I found some nice 270gr. Kieth bullets, but loading data for this weight is a little thin on the ground. I have found loads for Unique and Red Dot. The Red Dot load may not be quite up to the task, but there seems to be some disagreement as to a Unique load. One source lists a 10gr load which it says is within SAAMI specs. Another says 9.3gr. is the max load you should use, and a couple of other places say you oughtn't to run more than 9gr.
The goal here is penetration; I'm OK with a hot load but I don't see any need to stray into 'Ruger only' loads. Recently assembled data suggest that many calibers from 9mm to 44 Magnum have been used effectively on larger bears than anything I am likely to run across. In fact almost every caliber used had a 100% success rate- including 9mm. Honestly I am not likely to run across a bear at all, but one likes to be prepared.
So your opinions: A 270gr. Kieth bullet at 800 fps. ought to do the job, but would I be better off going a bit hotter? 900fps? 1000fps? What do y'all think?

If 800 FPS takes you where you need to go, I say go no further. Less recoil and blast makes for a more pleasant experience.

You don't mention what six gun you will be packing but that 270 gr bullet is a dandy if you want penetration. As always it's best to shoot the load that you are most effective with, bears or other predators aren't impressed with misses. We all read stories from time to time of bears or other large game being killed with 9mm's & other small calibers, that doesn't mean it's a good caliber for bears, it means someone got real lucky & survived a bear attack. Use the most you can handle if you expect trouble & you'll be happy if it ever happens. No one ever wishes they had a smaller gun if they get attacked by a 2 legged or a 4 legged predator.

Yes, what gun will u be shooting these from ! If Unique will give you 1,000 fps safely with your bullet, that is what I would use. A 270 gr boolit @ 1k is really a mild load far as bear loads go !!

Has anyone seen or read data on medium bullet weights but with monometal bullets??? Just curious because I was thinking that those bullets might get you into bear protection type penetration levels. Was thinking of female or kid type recoil levels, being a bit more tolerable at 240gr @ 1000fps or so.

Search for 'HL 246Partial,' which is an excerpt from Handloader magazine where Brian Pearce wrote an article about this bullet/cartridge combo, to include load data for different pressure levels. If you can't find it, send me a PM with your email address and I'll see if I can send it to you. Pearce does use up to 10.0 grains of Unique for his Level 2 loads.

I'll be shooting these from a 3-1/2" custom Sheriff's Model made from a J.P.Sauer/Hawes Western Marshall. It's a .45 Colt but is built on the same frame as their .44 Magnum. I wouldn't run 'Ruger only' loads through it, but it runs hot loads just fine.

Are these sources reloading manuals? Reloading manuals are not hard and fast formula. They are just published reports of what a lab found when they used their components in their test equipment, both of which can vary from other test facilities. If in doubt, start with the lowest published load, then if necessary work up...

If in doubt, start with the lowest published load, then if necessary work up... Guns, methodology and other conditions vary so it's always been the gold standard to start 10% below the listed load and work up. I plan to load several loads and test them all. The winner will probably be a compromise between oomph and slowing down follow-up shots too much; I very much doubt it will be a max load or anything like it.

"Not actually for hunting", a back up, sidearm around camp gun. I'd stay sub-sonic. You can get where ya want to be with Unique, or PP or Longshot, HS-6 and such. Even though the mag frame sized gun can handle them, I'd avoid the slow burners, H110, Lil'gun and such. IF you have to shoot sumpin' bear-sized it will be at short range and inbound..

That 270 SAA boolit is a very accurate chunk of lead! I wish I didnt sell my mold for that boolit. I used HS-6 with mine but Id have to review my note to say how much.

I scrolled back up and saw how short the barrel is and guess staying sub-sonic will not be a problem ! I'd still avoid the slow burners. I've had to fire 44mags and such after dark without time to put on eyes n ears.
