There has always been a common thread when reading about Marlin lever guns and their 1894 .44 mags when perusing the various forums. Accuracy! Or, lack there of it. I love Single action six-guns! A good lever gun just seems to be a natural companion to our favorite hip shooter. Many people being stout followers of the Grand old man himself, Sir Elmer, the .44 mag is a justifiable choice. The only problem was that if you wanted a Marlin lever gun, you would be frustrated trying to get the thing to shoot decent groups. Jacketed, cast, hard, soft, checked, plain base, it didn't matter. The Marlins were more finicky than a 10 year old at a vegetarian buffet. When I shot mine, I actually scoped it after several range sessions thinking the large groups were my fault. Once scoped, the groups remained the same. The scope was removed, and the gun banished to the back of the safe, to the non interesting, or remedial group of poorly mannered shooters.

Alas, the sentimental side of me loves a happy ending. A few weeks ago, I stumbled into PC(powder coating) bullets. To say I was impressed, would be a huge under statement. Long story short, the PC bullets appear to be to greatest innovation to cast bullet shooters since invention of the humble gas check. With the extremely positive results I obtained with six-guns, and a 1894c .357 Marlin, I got to thinking of that lonely .44 mag lever gun. Would PC bullets coax it to better accuracy? With nothing to lose but a try, I dug out the rifle, dusted it off, and loaded up some ammo.

I loaded up three different bullets, all over a stiff charge of 22 grs of H110. First was a Lyman 250 gr RFN cowboy bullet of plain base design, second was a 280 gr WFNGC design, and lastly, a 265gr Ranchdog designed slug with gas check. I also loaded some of the Ranchdog slugs without GC to experiment.




First up was the plain base Lyman 250 gr slug. 10 shot groups at 50 yards would be the test norm. Looking thru the peep sight after the first 4 shots, I could make out a hole in the target. I shot the fifth round, loaded 5 more, and then checked the target. The blue painters tape is 1.5" .




Damn! This was the best group ever shot by this gun! I had to shoot again! see if this wasn't some kind of cruel fluke. 10 more down the pipe.


WhooHoo! Things are looking up! Next up was the RanchDog bullet with gas check applied. 10 shots, 50 yards. check the target.


Looking good! I'm getting excited! Now to try 10 RanchDog bullets without a gas check. same routine. 10 shots, 50 yards. Check the target.


By this time, it would take a bulldozer to wipe the grin off my face. I got it to shoot. These darn PC bullets are something else! Lastly, I tried a WFN slug weighing in at 280 grs dressed with a gas check. You know the drill. 10 shots, 50 yards. Check the target.



As I mentioned in my previous post, the more I shoot these PC bullets, the more impressed I am. I also shot a .45 colt Bisley Hunter and a rather troubled 4" Ruger RH that always gave me fits. But that is another story for another day. I will give you a hint. I'm still smiling and in a state of amazement.

Thats really good Jeff, getting a Marlin to shoot lead can be a bit of a chore, looks like you have it figured out, even without GC's!!

I suspect it was not so much the powder coating, but the .002 added diameter you reported in your earlier post that is added by powder coating. If your Marlin 1894 44 mag was built before 1998 it had a rather generous bore. Now that you know the size bullets it likes, it is likely to shoot well with non-powder coated bullets that size also. Way to go !!!

jgt, that may be for the unsized plain base slugs, but the gas checked slugs were sized thru a .432" Lee push thru sizing die, the same as used before the accuracy increase with regular non PC bullets.

Chiefuzz, I'm not exactly sure, but am willing to give you my opinion. I think the PC is much harder than the hardest of hard cast slugs. While 22 bhn was considered pretty darn hard for a cast slug, people report the PC being as high as 45 bhn. Jacketed bullets are about a 60 bhn for comparison. I believe the harder PC engages the rifling better, with less chance to strip it, or skid, with heavier loads as it travels down the barrel. Whatever it is, it works.

Well, What your doing works really well. That is an interesting fact about the hardness of the PC bullets that I don't remember being mentioned by anyone else. I knew Veral Smith's book told how to bake cast bullets to harden them, so it makes since they would harden after baking the powder coating on.

jgt, I should have been a little more specific. The powder coating material is what is harder, approx. 45 bhn. The lead itself would be annealed, or softened to about a 10 bhn.
