Anyone know where I can get a brush that will be the correct size for my Mosin? Preferably one that will fit the rod that comes with the rifle but one that attaches to a Hoppes rod will work too.

 

Other than that any other tips or advice for cleaning it?

a standard 308 brush will be ok. If you want something a bit tighter, get some 8mm bronze brushes... it will be nice and tight in there.

I actually use a 10mm bronze brush to scrub mine.

7.62mm x 1 inch/25.4 mm = 0.300 = 30 caliber

7.62mm x 1 inch/25.4 mm = 0.300 = 30 caliber

 

That's what I use, the 30 Caliber bore snake.

 

308, 30-06, 300 WSM, 303, 30-30, and the Mosin

I use a .30 cal as well.

I also use a 30 cal brush. Actual diameter difference is negligable as far as brushes go. .002-.003" up from a .308
