The toughest part of this post is figuring were to post it, figured since most rifles ever made in this cartridge are levers this might be the place. So does anyone have load data for this necked down 45/70?
I also shoot the 38-56 in an 1886 Winchester. What rifle are you using? You should have the bore slugged to determine the groove diameter. The 38-56 is supposed to have a max dia. of .3795, however, they can vary to as little as .377, depending on the rifle. Colt Lightnings have tighter bores than Winchesters typically do. My rifle shoots well with .377 dia. bullets. My favorite hunting load is 250LFN/36/3031. This provides good accuracy with plenty of power to take any "lower 48" game. I have killed both hogs and deer no problem. Remember, this is a 200 yd. tops cartridge.Brass, dies,etc are available from Huntingtons. They aren't cheap, but it's a fun cartridge to play with. Enjoy.
Thank you Charlie and Mike. I already have Ken Waters load data but can't go wrong with his data either. The rifle in question is a rechambered Ruger #3, originally a .375 Winchester this is why I questioned where to post this question. I don't know why the rifle was rechambered, just figured there might be someone with some data different than what I have. The barrel is .375 with a 1 in 12
LIB, This is interesting, indeed. I am at a loss on this one. With a #3 as a platform to experiment with you are in new territory. You will have to experiment a lot with this one. Case capacity is not an issue here. The problem is how far do you want to go? This will take some thought.
Just wonderin', LIB,
Have you done any experimentin' with your Ruger? I wonder why someone would rechamber a 375 Win. to an obsolete cartridge like the 38-56? The twist of the original '86s is 1 in 20", and your gun is 1 in 12". I think it may be a little fast for slower lead loads, but should work fine with the same bullets designed for the 375. I would like to hear some results on this one. Cheers, mike
NITRO, The loads listed in COTW are good, but there are better out there. I've actually gone as high as 40/3031/250LFN with good results. Also, 38/H335/220FSP is a good hunting load. Last evening I loaded 10 rds using 28 grs 2400 and .376 LRNs. I'm going to try them at 100 yds just to see how they do. Had the bore on my '86 slugged the other day. The lands are .374 and the grooves .380. It shoots well with most bullets with diameters up to .377. Not too bad for a 112 yr old gun. Keep 'em in the black, mike
I loaded some ammo for my 38-56 this morning and headed out to the range to give' em a go. These loads consisted of a 255gr. .375LFN over 26/2400. Accuracy was non-existant with many keyholers. I need some advice with this problem. Are the bullets too small for the bore? Is the powder not expanding the bullet enough to fill the bore? I have not used gas checks in any loads for this cartridge, so far. The bore is in very good condition, with lands at .374 and grooves .380. All help will be greatly appreciated.
It would appear that the groove diameter is several thousandths greater than the bullet diameter and seeings as how you are using a fast smokeless powder, I doubt that the bullet is being "bumped up" to fit the grooves. I would try a bullet about 0.001" greater than the groove diameter.
