A couple years back I picked up a Savage MkII bolt .22lr at a gunshow. Nothing special to look at, but I grabbed it because the price was more than right...I thought...and the gun was equipped with a section of picatinny rail mounted on the barrel for scout scope use. I figured it would make a good rimfire scout trainer, and it has; I've put roughly 2000 rounds through it so far and it is a shooter. If fed premium quality ammo it will do 1MOA at 100 yards...even with cheap crap ammo (I use it with whatever I can find on sale) it usually shoots 2 or 3 MOA. In other words, I'm not complaining...except...

The pic rail is held on with 4 screws, and one of those damned holes is drilled right through into the bore! It's virtually invisible when eyeballing the bore with the scout mount installed. I recently took the mount off, simply because I wanted to apply some bedding compound between it and the barrel, and that's when I noticed the hole with the light shining through it.

It seems pretty safe to say that this isn't a dangerous condition; if a couple thousand rounds haven't revealed a problem I think I'm in the clear. Any suggestions or comments? Should I do anything to this? Or just keep shooting the crap out of it? I obviously can't sell it, so this is one of the guns I will die with. Cutting the barrel off at the hole is not possible, as it would result in a prohib. I was thinking I would replace the scout mount, put a dab of bedding into the hole before replacing the screw, immediately run a few patches through the bore to remove whatever was squished into it, and then after the compound has begun to solidify shoot a box through to polish out whatever residue might be left behind.

Thoughts?
 
Don't lose sleep over it. The mounting screw plugs the hole. The imperfection in the bore will do no more harm than a gas port.
 
Love that, showed it to the wife ,she loved it too,showed it to her friends, now it's all over! Flo like it?

Don't you no never mind 'bout Flo's holes...............:rey2

I’m happy to be able to read your posts mr looky......congratulations on your sobriety!!!

Well you can blame some of them whole holes awn'ear for my Newsyears kawnstitewshun on cutting back awn lookanese.................d:h:
 
Thanks, gents, the excellent comparison to a gas gun with a port in the barrel didn't even occur to me...too much Fudd in me, I guess... :)

Common sense does indeed say "If it ain't broke...don't fix it."

Unfortunately, OCD usually says "If it ain't broke...let's see what we can do about that..." :)
 
I had a 45-70 with a hole drilled right through. It was plugged with a 6 x 48 screw with enough space above it to accept a screw for mounting the rear sight. Gun shot fine and safely and no I was not the person who drilled the hole

Well, last night I ran a sight-hole plug screw down into that damned hole as far as it will go without protruding into the bore. It's secured with a tiny dab of epoxy in lieu of loc-tite. This morning I cleaned the threads above that screw with a tap, then re-attached the base with four screws (one now shortened slightly) as well as a thin skim of bedding, which is what I wanted in the first place. I'll pop the scope back on tomorrow and test it, but I see no reason for it not to work perfectly.

The worst part is that I actually do inspect used (and new...) guns pretty carefully before purchasing. This slipped right past me. I wonder how many other surprises lurk in unseen corners of some of my guns.

Ignorance can indeed be bliss! :) Thanks to all for your comments.
 
I woukdbt worry much about this on a 22lr. If it hasnt blown out after 200 rounds its not likely to. Id be more concerned on a high pressure center fire than i would be on a rimfire.
