inherited a 1917 with a pitted barrel from my dad

Patrick - what you describe makes sense. I'll see what I can find. Have you had great results with a particular round?

Dif rifle, similar potential problem... VZ24 7mm Brazilian. Lands very worn. Last 1- 1 1/2" of muzzle ends up looking almost like it has been counter-bored. But before that - there was serious rust in that last 1 1 1/2" of muzzle!

I stuffed it w/ Kroil soaked patches for about 10 days (didn't intend to do it that long, but...!) Then soaked an oversized brass brush in Kroil and used a drill to spin it in the muzzle end of bore. Figured I couldn't make it any worse! DID clean out the rust, and not a lot of pitting, so that's good. But as mentioned above - nearly a smooth bore at the muzzle!

Waiting to see how it will shoot. If I get 4-5" groups at 100 yds (and my old eyes) I will be ok. Time will tell.

Yes, the Hornady round-nose flat-base Interlock bullets are my first choice for dodgy milsurp barrels - they have a very long cylindrical portion. They have worked in barrels where boat-tails were hitting the target sideways - or even not at all!

Never had to resort to them, but I have also been advised over the years that the heaviest, albeit longest bullets for caliber will do better in a worn out milsurp bbl. And yes, that is typically the heaviest RN FB you can get. BTW - this is what a lot of the calibers were originally designed/loaded with...

I have had absolutely great results using Hornady ammunition. I just wish it wasn't SO pricey. You do get what you pay for, I just don't get it in bulk.
