Think I've got a shooter. Took a half day off yesterday to take advantage of a sunny day in No. Calif. Targets are at 100 yards. The barrel had been leading a bit before and on some previous range sessions I ended up breaking in with 50 jacketed bullets and it was still leading a bit so I ended up putting 15 firelappng bullets from Bear Mountain. Leading no longer a problem.

So from an absolutely clean bore the first 5 shots were not that great. About 5 inch group. Next 5 were about 4 inches. Next 5 about 3. Hmmmmmm. Targets below are the 5th and 6th groups. The next 3 were similar. Hmmmmm. Cleaned the bore again and same thing, big groups that kept getting smaller. I think my rifle likes it dirty. Now I wonder how long it will shoot before it gets too dirty. Gee, I guess I'll have to shoot it more.

This just became my favorite rifle. Hell my Lyman scoped 270 Remington 700 doesn't shoot this well.

Had also experimented a bit with powder and bullet sizes. These were all shot with Bear Mountains 250gr GC at .377. Powder is 4759.

I like a gun that isn't too prissy about being clean. Nice shooting!

good shooting!
my .356 rebore from JES does the same thing
first shot from a clean barrel is about 4 inches out, the next four are a tad over 2"
just something a guy has to live with I guess

Thanks guys. I never thought I would have this much fun with the old Marlin that sat in my gun safe for 20+ years.

Nothing like re-discovering an old friend that's better than ever!

I shoot H-4895 in my JES re-bore.It shoots about an inch at 100yds. with my cast bullets.

I have a couple of BC Remingtons (Before Cerebus) that require 12 to 15 shots to settle down again after cleaning or after a bullet change. They are both super accurate but must be permitted to do it their way.

Yeah that sounds like what I will be doing. It took about 15 or so rounds before they started looking good. I too have been accused of being a slow starter... but thats a whole nother story.

I think that's true of a LOT of guns. Very few of the guns I've owned have shot well from a clean barrel, but there were a few.

Unique has not played well in my Swift.

Swany are you thinking the Unique would help the cleaned barrel shoot better sooner? If so I'll give it a try but otherwise I'm pretty happy with the groups the 4759 is turning out.

Hey there Hunterj50 -- I don't think swany was suggesting that Unique offers any advantage in clean or dirty barrels. A lot of us have found Unique a powder that helps with accurate loads for a number of reasons. I agree it wouldn't hurt to run a few 10 grains of Unique loads through your rifle and see if it makes your groups even better. It might not help any as well. Most of my rifles like a fouled bore to some degree or another. The trick if finding the limits. Best regards. Wind
