CVA Double Bbl 12g shooting .690 Patched Balls :)

[Marlin_444]

Hey All,

Anybody shooting a smoothbore in .69 caliber?

I picked up my NEW (to me) CVA Dbl Bbl 12g last week, loaded it with 70 Grains 1/2 & 1/2 Pyro / T7 under a double lubed patched .690 grain lead ball.

Seemed to patern well at 50 paces but I want to see what it will max out at.

The fella I got it from said he shot 80 grains.

Anyone have any experience with this type of smoothbore shooting?

Thanks for your input!

See you in the woods...

Ron.

Two questions:
-Are you mixing 50/50 Pyrodex and triple seven powders?
-What size is the pattern at 50yds?

I have shot 69cal balls from SXS guns and find that the barrels rarely shoot to the same POI. One suggestion might be to see which barrel shoots to the POA of the sights and use that one with the PRB and the other barrel with buckshot. Might be a good deer combo.

I've also had a tough time getting regulation. But Hellgate's solution is an excellent one. Make one barrel the designated roundball barrel.

I've noticed that charge level doesn't seem to effect accuracy that much out of smooth bore, but patch tightness does. A tight fit is going to get you the best accuracy. I have a big brass-headed dowel I use as my range rammer to avoid snapping the thinner ramrod.

Also try the real 2F if you can! It's the best stuff.

Did you pick that up over on Gunboards? I just missed it...CONGRATS!

I replaced the wooden ramrod with a fiberglass one using all the original hardware. No need for two rods.

I love the way it shoots...



Hellgate - Yes, I use 50/50 Pyro & T7, though about a Buck-N-Ball secondary load; and or a Buckshot Load.

Cosmoline - I need to shoot it more to determine a pattern & POI, Hellgates 1/2 Ball & 1/2 Buckshot is in line with my thinking, I use two lubed patches. tried three but they were too tight... I may go with 2F/Goex after I shoot up my 50/50...

BHP Fan - No, I picked this jewel up off the new www.forum.gon.com Swap & Sell Forum.

Hellgate - It came with a fiberglass road, may not be original since it is a '84 model ith 26 years of experience...

See you in the woods...

Nice. I've always liked SxS doubles. I absolutely love my 20 gauge Howdah pistol. I want 1 each, Pedersoli 10 gauge, 12 gauge, 20 gauge, 12 gauge coach gun, 12 gauge slug gun, and Kodiak .72 caliber double rifle.
I don't want much.

At the last gun show I want to, back in '09, the only guns that WEREN'T grossly overpriced were original BP muzzleloading SxS doubles.

Why are you mixing the two propellants?

I use two lubed patches. tried three but they were too tight

How thick were the patches? If you're already at two patches with the .690" roundballs, you might do better getting slightly larger roundballs. .715" or .710"

Either that or use .018" or .020" pillow ticking for a firmer grip than two thinner patches stuck together. You're almost making a sort of shotgun sabot with thick patches, and they tend to shoot better.

I just picked up a yard each of various thicknesses of material from track. It's just a matter of cutting them in strips to size and dipping them in a mix of olive oil and beeswax. Then you use your patch knife to make the final cut to size as you load from the strip. It's the patch version of a revolver's speedload strip. You can keep much better control if you keep the patch material in strip form rather than trying to balance a fully cut square or circle on top of the muzzle.

I played with .710s in my Beretta, patched with .015 ticking and backed with 75 gr. of FFg. At twenty yards, the ball penetrated four 2x6 planks and lodged in the fifth. Actual "gauge" dimensions vary not just from maker to maker, but from gun to gun from the same maker, so mike your bores and find the ball/patch combo you need. Pattern the load before you try to take it into the field, as your barrels may not be regulated all that well; also, I found that round balls hit higher on the target than I expected. YMMV.

I would not hesitate to use that load on an elk, within 60 yards or so.

I've always enjoyed the shooting of Double's in Black Powder; just some extra confidence when I am Bear Hunting... I have owned Pedersoli 50, 54 & 58 doubles and they all shot well (READ: Kicked Like a Mule also)...

This '84 CVA shot very lightly, it is a shooter and has been used in the field "A LOT" again it's a shooter and not a "Safe Queen" - I do know that right now there is a '85 for sale on Gun Broker for $300 plus in fine condition...

I paid $200.00 cash for my "Shooter" grade and I will hunt hard with it; I'll be happy with 20 - 40 yard accurate shots...

See you in the woods...

No particular reason; I just had a 1/2 bottle of each

Specs from CVA War Book is .690, at some point I may run up the ladder to .710 or .715...

Seems that pre-lubed patches are .10, so ticking that is .20 will work best; I just picked the double up a couple weeks ago and have not really shot it more than 4 times, twice at 40 paces to test fire it then again at 40 paces to unload it...

I will get some pillow ticking at .20 and soak them in lube; but for this season, I'll go with the double patches.

Seems the right barrel slides in a bit looser than the left, not sure but it may be that the right barrel could have been shot more often.

The gun has double set triggers, you can pull the front trigger for the right barrel, then the rear for the left; however if you pull the rear first you will unload both triggers at the same time... That's 160 grains of powder under 1380 grains of lead (80x80 - 690x690) if my math is right, so I'd expect a "THUMP" on both ends... WOO HOO...

I plan to work out a load after the season ends (1st week in Nov - I believe), we only have a 1 week Black Powder Season here is the woods of Alabama...

Until then, I will dance with the one in my arms; however I do plan to use it during Turkey Season in both Georgia and Alabama; so I'll need to work up a Scatter Gun load too...

Gotta love a versitile weapon that harkens back to a simpler day and time...

I love the smell of Black Powder in the field!!!

See you in the woods...
