chamber reaming

[Jason313]

can anyone recommend a good smith for a chamber reaming, that is cheap and fast turnaround? I want to open them up to a .451 and currently a .449 if its to specs. the groove is exactly the same but im looking to increase pressure/ velocity by way of resistance (maybe im over simplifying but seems to me to be pretty much the same physics as a power nozzle) as well as improve accuracy by pushing the .451 ball down the .449 barrel. Any thought on this? and a gunsmith that works on cap and ball?

 

[Jason313]

it seems im not getting much punch as is, barely any recoil even with a 45 grain load of dex

 

[troy fairweather]

u can do it your self just rent a reamer why u need more power btw

4d reamer rental has a cylinder reamer for 45 for 36.00 for a week u just will have to use 457 balls.

If you find one I’d certainly like to know as well. My barrel is .452” with .449” chambers after reaming.

Figured I’d just buy the hand reamer but that wouldn’t help with any future Pietta .446” chambers as the reamer doesn’t have a guide that small.

if i had one of the reamers id make u a pilot on my lathe

Reaming the chambers is a lot of effort/expense to accomplish little if anything. A soft lead ball/bullet will bump up to bore diameter as it passes the forcing cone. Regarding recoil, you mentioned as 45gr charge of Goex I presume you are shooting a Walker or Dragoon so you are not going to get a lot of recoil due to the weight of the gun.

That depends on how grossly undersized the chambers are. The Pietta copy of the pocket Remington is one where that isn’t quite so.

But those who compete claim it is certainly worthwhile and the difference noticeable. We see that every modern lead bullet is 0.001” over bore for a reason, though some of those are harder and can’t obturate. But not all, and for a reason it would seem.

Quite frankly I don’t know for sure that it makes hill of beans to an average shooter. Maybe, maybe not.

well mainly juyst on GP, if i wanted something that went bang and shot sparks id have bought fireworks, when you shoot a .44 you should feel that muzzle jump, its like the power of it that makes shooting a big bore gun fun IMO. Also you have to keep in mind not everyone on here has the same freedoms when it comes to the right to bare arms, for some these are (by necessity) their go to weapons for home and personal defense and even as a CCW, in which case power matters.

I should be more specicfic, it was about 45 grains [pyro]dex BY VOLUME but that stuff compresses down so much that i can put that and a wonder wad and 451 ball in my pietta 1858 on top of 40-45 grains using the on board loading lever

 

[Jason313]

I have read from quite a few people they are getting velocities about on par with somewhere between a .38 special on the low end, and .45 acp on the high end, I've shot plenty of both and the kick im [not] getting is not close. Im using .451 balls but they shave a small ring still so making a seal in the chamber

 

[44 Dave]

What I have done with mine is first remove the nipple, chamber a ball or chronicle, Then push it out and slug the barrel with it. this shows if you are getting full rifling. Odd number of groves and lands are hard to get accurate measure.

 

[Noz]

I had the OPs question done to a pair of Uberti 1860s and as far as I was concerned it ruined them. Even with a 457 ball my accuracy was hopeless.

this confuses me I thought the chamber should be slightly bigger than the bore?

heck a bb pistol will make a lot of would be attackers stop and think twice get one of 40 shots one or even a 357 /45 bb pistol in semi auto
most will stop when they feel the pain and except for winter clothing it is going to be very painful
up to 50 ft almost guaranteed will puncture the skin

If a crazed tweaker, loaded to the gills on God only knows what, comes at your wife and or kids with a knife screaming at them to stop trying to steal his thoughts, I really really hope you would not be stupid enough to shoot at him with a bb gun, better to simply run away if thats the best you can do at defense. Even id, lets just say, you had a high power PCP air gun that could seriously wound someone, and, lets just say, it would wound badly enough to stop the attack. The law does not allow for the use of sub lethal force with a [legally speaking] deadly weapon, at least not in my state or any others im aware of. THe law states that a person may use lethal force to defend ones self or others from a felony assault, if you are unable to flee and avoid it that way (no stand your ground law here, other states may not require one to flee when possible), sub lethal force however is not allowed for, basically if you shoot a guy in the leg to stop him, or blast him with a PCP air gun you may very well end up in cuffs.

i think the whol;e issue of Guns and gun control, and 2nd ammendment issues, all comes down tio a fundemental difference in thinking about whos responsibilities it is to keep us and our families safe. one camp says its the job of law enforcement, we pay them and train them so we dont have to worry about protecting from harm. the other side says that while police are a good thing and we hope they will be there to help when we need them, but ultimately the duty to keep ones self and family safe, falls on the individual, its my job in the end, the buck stops here.

 

[paul harm]

I believe it's been taken to court and the police are NOT responsible to guard/make you safe/ protect you. How many police would be necessary to give everyone a body guard ? All they do is come and make a report after the crime has been committed and try to then arrest the bad guys. The 36 and 44 BP revolvers killed many a person WITHOUT reaming the cylinders. Just because it doesn't recoil like a modern gun doesn't mean it won't do the job. 44Dave, you wouldn't be getting the bump up effect a soft lead ball gets when the gun is fired.

 

[saaman]

My ASM Dragoon would not group on paper with any load until I reamed the undersized chambers.

Maybe you ought to step up to a Colt Walker or get a double barrel percussion shotgun.

However, I just don't think black powder recoils like smokeless powder.
For instance, I was shooting 120gr loads of FFFg in my Lyman Great Plains rifle. Didn't notice that it kicked particularly all that hard. Though I was wearing a winter jacket.

Last summer I was firing my neighbors Uberti 45-70 lever action with black powder cartridges loaded to the max with compression. Nothing to them them - wearing a T-Shirt.
I've fired smokeless 45-70 Marlin Guide Guns in the past in left me black and blue with a flinch.

I have a 300 win mag in my safe - that beats the heck of me. It's ready to be traded.
