Savage 24v accuracy problem

swampthing36
Guys and gals:

I bought a Savage 24v Series D end of last year. It's a 223/20ga. Just started shooting it recently. I can't get it to group at all. I've had two different scopes on it; two different sets of rings, and have fired 45gr, 55gr, and 60gr bullets. Shot Benchmark and Varget powder. The gun will hit the paper at any given distance. But each consecutive shot will be 4 to 6 inches lower than the one prior and near-perfectly in line up and down. What in the hell is going on? The scope rings are tight. I have the scope base screwed onto the barrel rib properly and the three screws are lok-tighted to. Please advise.

    You didn't mention cleaning the barrel. If you haven't been doing that, and have fired quite a few rounds, give it a really good cleaning. Use one of the copper solvents as well as regular cleaning. I have a 24V (223 and 12 gauge) and couldn't be happier with the accuracy of the rifle barrel. It will shoot under an inch with most anything I feed it; including the inexpensive red and white box Winchesters. I have found a few loads that it doesn't like; mainly heavier bullets in the 60 to 63 grain range. You might also try shooting only a couple rounds and letting the barrel cool for 15 minutes or so before shooting again. I've got a couple of rifles that won't group well when the barrels warm up but will shoot in to a half inch if you keep the barrel cool. Not great when overlooking a prairie dog town but fine for most hunting conditions. Good luck with that 24V; they're great guns.

    Hi Swamp thing---I'll give you a WAG. I'm thinking that the two Bbl. are acting like a bi-metalic strip, such as you will find in some thermostats. I'm assuming that the .223 bbl. is on the top, with the 20 ga on the bottom. When you are shooting, the rifle bbl heats up, disproportionately to the shot gun bbl. As the rifle bbl heats up, it expands faster (in lenght) than the shot gun bbl does. Then, like the bi-metalic strip, the barrels together are forced slightly down over their lenght. That would creat a lowering of your point of impact. Spose??? Just for kicks and giggles, the next time you shoot, shoot the .223, on target, then fire a 20 ga off target, then back to the .223. etc. See if the point of impact is more consistent. Or---Let the .223 cool down between shots so that both bbl. are the same temp every time. Let us know what you figure out.

    Hawkshaw has the correct cause for your group size moving IMHO a dirty bore improper loads will give you large groups but in a random pattern . If they are in a line top to bottom then barrel temp is the KEY.

    Guys thanks for the responses. The bore of the barrel is spotless. When I bought it I ran sweets 7.62 through it along with Hoppes #9. I also ran lead remover through it. I am a stickler for clean bores. I have shot the gun very little; but I am not the first owner. The lands and groove appear sharp. Bore is shiney. The crown looks good but I need to use a glass on it for close inspection. I haven't shot the shotgun barrel yet. It is quite cold here in mid Michigan. Barrel barely gets warm. The barrels are soldered together at the breech end, and have a short rib at the very end. Otherwise independent. I have trimmed all my cases, uniformed primer pockets, cleaned out flash holes, handloaded and measured C.O.A.L.

    SWAMPY,

    A couple questions for you...

    1. How is the scope attatched to the barrel? Is there a drilled and tapped mount, forsay like a weaver type base, or is it a 3/8" dovetail like a lot of 22's?

    2. have you shot ONE shot, let it cool for 10 minutes, then shot ONE more shot, and let it cool, etc, and seen how the group reacted?

    These are not benchrest target rifles, and if the scope is not mounted solid, that could be your problems. Infact, if it has just the groovs, Savage even reccommends not shooting it with a scope, when using the shotgun.

    Best

    There is a solid rib on the top barrel that has three screw holes for attaching a base. I have a brand new weaver base on it. Last night I pulled the scope. I had lock tighted the screws in. But when I went to pull them out, the screws were barely tight. I didn't have to fight the lock tight at all. may have therefore discovered the problem.

    I will shoot it with the iron sights this weekend. If she still strings, then I'll have to come up with plan B.

    It's heat.First 2 shots from mine are right on & then they start down. Also. The fining pin has broken twice in mine. Less than 100 rounds.

    A combination gun , shotgun/rifle, by design is mostly intended for hunting with one or two shots on a cold barrel. Firing multiple rounds was never intended, such as clay birds with the shotgun or quickly spaced rifle fire. Some models address this heat/vibration situation better than others, Zoli incorporates a free floating rifle with a mid barrel regulator block, CZ allows the rifle to free float even at the end attachment. Drillings with long barrels soldered to two shotgun barrels allow for heat transfer and create a very stiff rifle barrel. A 24v has the barrels attached solidly at the end. You may try wedging in a pliable material between the barrels midway.
    Let us know what you discover.

    Some of the 24v's were rechambered to .223 from .222 and over stamped the will have the wrong twist.tks hedge.[:D]

    I had one that did this - in the end-- I had to conclude it was just a bad barrel. Sent it down the road.

    I doubt I will go to the extent of doing anything to the barrels. If I can't get it to shoot even a three shot group, I'll probably send it down the road.

    I don't think this one was overstamped. From what I have discovered the twist rates for the 222 and 223 were the same in the 24V.

    like i said mine is the same. i've always thought the problem was the barrels being attached at the muzzle. i have always belived that barrels actually "whipped" or had harmonic vibrations as the bullit passed thru it. having two barrels attached at the end would not allow this to happen. i really like the gun but accuracy sucks. from what i've read it looks like there are two options,sell it or live with it.
