Who out there has a 1858 NMA Euroarms .36? Just loaded this on and the opening of the Chambers are wide , no ring gets made, no shaving.' like the .44's. A good feature. 22gr of BP under a .380" Lee molded by SG ball.
My question was about the loading lever ram...this one is flat unlike the .44's I have. Is an XX7 Hawes L.A. CA Euroarms. It just seemed strange that it was flat...anyone know about it?

The chamber mouths could be chamfered. Some guys do that to ease loading of conicals. Dunno about Hawes

The volume of lead in a chamber, especially when it is compressed against the chamber wall, dictates the amount of force required to propell it from the chamber if a "given" velocity is required. The fact is... if the charge is constant.. a larger load in the cylinder, compressed only adds friction weight, the load will move slower from the gun.

Keep the same load, but cram more in... slower ballistics.

Yeah they are chamfered that's what I was sayin' ...that it's a good thing, tight after the chamfer.
Hawes L.A. CA was here in 1971 XX7 is the mfg. date...a new 1971 CA Euroarms Rev....I gots it!

Whatever you wanna think Ron. I'm not arguing about it. I haven't heard anything my .454's have hit complaining about the bullet going too slow after being pushed out of the chamber by 35 grs. of powder and as long as I can hit a softball sized target at 25 yds. I'm happy.

I'm going to bed now. I'm too tired to argue.

Goodnight Ron, SG

Tell me if this is right? .454 - .451 = .003 ; .003 / 2 = .0015
.451 - .445 = .006 ; .454 - 445 =.009 a .003 differance right? Both balls will be shaved .001 to .003 reguardless and will be the same size ball in the chamber.

Yes, but even that little bit can make a difference.

They will be physically the same Ron...think chamber size.

It's about mass in chamber size, and the amount of mass touching the chamber walls, and how deeply, and the distance and size of the charge.

Nope Ron and that's a fact. We are talkin' about Black Powder C&B Revolvers, not a 155MM SP Howy....

Every micro ounce you notice, always. Everything in this hobby is based on weight and the force required to move it.

Wow, do you even understand the concept of mass, friction, speed?

That's varmint, or 1000yd target/sniper shooting...I know cause I have done them both. And the Reason I am still doing Black Powder instead of other more complicated shooting is because it is relaxing and not difficult...it's actually very simple.
Messy but fun and simple.

Did you get a hand spring made or one to work on the Navy? Come on up I got some feeler gauge stock I'll make you one...and I think the Uberti hand will work...I had made one for my Uberti Navy, can try it...or I'll make you one.

Whatever. Keep on keepin on bro. It ain't worth arguing over.
That's the truth.

RP - go get the data (measured) and publish it: velocity and energy at 25 yards.

I'm with ya there bud, I've been using .457's in all my .44 caliber C&B revolvers for over 20 years & have allways been able to hit where I was aiming at & yet have plenty of energy to do damage to the target be it paper, metal, clay or an occasional Yote & so far I've yet to have a problem with any of em in that many years associated with using a larger diameter ball than the chamber & I'm no slouch in the powder department either.

I loaded 454s...

round, thick shaving rings. I'm guessing .451s would go in with very thin shavings. But don't have any around to try.

As for the above discussion--Couldn't one just measure the chambers?

I couldn't because I don't think my dial caliper is accurate enough. But a smart guy with a micrometer or something?

Speak of the devil, i think my Pietta Rem. NA is a little camfered... it doesn't shave any .454 lead but it's the most accurate of my NAs.

thanks, I matched the new handspring to the original and it works fine.

I have a Pietta 1858 and have had great results with .451 Speer balls.
I'll get to test it. When i want to my local shop to stock up on .454 balls they were totally out. so I bought a box of .451 .

Also I'm out of real black powder. And the shops around here only stock Pyro or Triple7.

If you go with 777 reduce your loads by at least 10%. I use Pyrodex mainly because it's a lot cheaper than anything else, 10 bucks per pound cheaper than 777.

My 58 has .440 lands and .450 grooves with chambers running .449-.450.
My 60 Pietta has .440 lands and .450 grooves with all chambers .450.

A ring of .001 is mighty thin indeed. I'll stick with .454's.
