pistol cylinder bored out?

Has anyone had a pistol cylinder bored out to accept a larger powder charge?How does the larger powder charge affect the accuracy?
 
It can't be done since you'd also need a larger barrel and bullet.

Don't experiment with explosives you hold in your hand
 
i am thinking about using one of my ruger old army's.What I have in mind is using it as a back up side arm for hunting which would include black bear.
 
The amount of extra powder you could fit in by relieving the back of the chamber would be negligible and do who knows what for structural integrity.

I would advise you to look into 777 and loads for it instead.
 
Dave Clements noted gunsmith makes 50cal's out of ROA's also reams out cylinders to accept 7grs more powder.Just would like to find out results of being done.
 
I've read that fer larger game the ft/lbs min. is like 500Ft/lbs. I like to adhere to that.
I would be easier to get "sorta close" to that with smokeless and a conversion cylinder and pick a load from the loading manual that gives the most ft.lbs.

If you just want the pistol for the "coup de grais" then a stout ball load with black would do it right up close.

You might hunt bears with a cap&baller if you were after bears the size of coyote.:eek:

If you were talking bout using a Blackhawk or better yet a Super Blackhawk Ruger that would be better.:D

I have some Classicballistix cylinders that give about 5 gr more than the factory cylinder and are actually a slightly tighter fit; cylinder gap on mine are 004 as opposed to .006-008 on my factory cylinders. I've used mine for coup de gras shots on deer during b/p season here in Ky, which the ROA is legal for deer here, but I haven't gotten a <50yd shot to try it yet. 40 gr of 777 behind a 250gr flatnose works great, but for bear I'd rather trust something with magnum pressure and large caliber.
 
At .457...

I find that my accuracy drops off if I go too high in powder.

Going to a larger ball or bullet possibly would stand more powder. Then of course, other pistols might shoot different from mine.

My guess is that Clements improves performance in one way or another but I haven't a clue as to how or what.
 
It's not a matter of power, it's a matter of reliability. Have you ever had a cap jam? That's why cartridge revolvers were developed. Do you want to have a cap jam, or a cap fall off, or fail to fire when a bear is charging you?
 
1st of all it would not be my primary weapon,I'd be using a 50/150 inline if I was after bear.2nd of all if a cap fell off 1/2 sec to fire the next round would not alarm me.Not everyone needs a 375 H&H mag to hunt rabbits.
 
My father-in-law shoots 40gr of 4f in a ROA. It really lets you know it went off. We haven't run it past the chronograph yet but I'm guessing its up there.

Thats the type of info I'm looking for.Wow 40grs of 4f,I'm sure thats pushing it atleast 1250-1300 fps.How accurate is it at that rate?
 
I guess you've never had a spent cap fall down inside the mechanism and jam the whole gun up. I have. I sure wouldn't want to have an angry bruin charging me if I had a cap jam. Cap & Ball is fun when your life does not depend on it. I'll stick with cartridges when the chips are down.

ROA for bear? Think I'd pass on that. Many better guns are available. Ruger offers centerfire revolvers that hit harder and are always going to go bang. Handgunning bear? Yes. With an ROA? If that was the only gun available and a threat or hunger where my motivation. Other than that, I think there are better guns available.
 
Is there a reason you want to use a C&B?
Just asking, because I wouldn't.
Bears are not known for being mild-mannered WITHOUT a bullet hole in their ribs. Frankly, I would carry nothing less than my Super Blackhawk in .44 and I'd be pretty nervous then, being a SA.
But, that's just me.....
 
Well...

There might be a good reason to use an ROA....

When the charging bear sees it, he might stop and exclaim, " Dag! An ROA!, Wanna sell it?!"
