JB bore compound and bore shine....

#1 Post by Sim G »

As you are aware, I piked up a 115 year old Marlin last week and I'm still in the throes of giving it a good "dig" out.....!

Anyway, when I first saw it, I could tell it had a repair to a split in the stock, but on the whole seemed sound. The barrel had strong rifling, but the bore was dark and had possible pitting....... but it was filthy! Light pitting on a bore of a rifle of this age, firing relatively low pressure ammo doesn't bother me. I have a 117 year old .32-20 Marlin with a lightly pitted bore and darkening and it shoots a storm!

Anyhoo, time to take the action all the way down! Some of these screws had probably not been out in an age! The cr@p in the mag tube must be as old as the gun......

So stripped down, time to go to work on the barrel! In the sunshine of the back garden (I'm only overlooked by one house from their top floor, and he's a retire copper who rough shoots!) I get to work. I give my usual cleaning routine but there's still a lot of "stuff" up the tube. Break out the JB compound!

An hour later and copious patches and compound, I start wth the JB bore shine. (I still haven't looked down the bore, thought I'd wait till the end and build up the antcipation! Another half hour and a wagon load more patches, I lift the barreled action to the sky......

NOT A MARK! Not one! Strong clear rifling and a bore that's not shiney, but reflective, all the way down! From the chamber end, from what I can tell with my untrained eye, the leade to the rifling has no or negligable wear! It's honestly like it had only just come from the factory. Initially, I had the horrible though that it had been sleeved, but it hasn't, it's genuine!

To say I'm chuffed is an under statement! This is in no small part to JB compounds, they are outstanding for getting the stuff out of the bore that you want to get out. If you're into old guns, get some!

In 1978 I was told by my grand dad that the secret to rifle accuracy is, a quality bullet, fired down a quality barrel..... How has that changed?

Sounds lovely, are you going to post some pictures of the finished cleaned rifle?

I have a tub of JB and the stuff that is saved for special occasions, I would not consider putting it down my 7mm but for Pre45 stuff that is really filthy it seems to work nothing short of miracles. I periodically swab mine out with methylated spirits in between scrubbing.

Cheers fellas!

I will take pics, honestly. But Rob has given me an idea.....

I've just taken the first. It's all in bits on the kitchen table and I'll take a few more as this goes on. Once it's done, I post them all in a time line...... with a narative! There's been a few other surprises for me as well, but they'll keep till the tale later!
