I didn't vote because a "get both" option wasn't there. If you're a lefty the m44 may occasionally poke your right hand, I don't mind though. I got an unused, arsenal wrapped, m44 and it's plenty accurate up to 200 yards. I chose it over a prewar m38 because a new gun will most often shoot better than a well maintained used gun. (same model)
I'll be getting a 91/30 or m38 eventually. But like was said before get the best bore, doesn't matter if it's a m38 or m44. Also if you're gonna shoot it much don't get a wartime manufacture, QC was real low at that time.
My m44 is 1947 made, never saw cosmoline, it sat in it's arsenal wrapper covered in gun/machine oil for years, the oil was coagulating(if that's the word) but cleaned off easily.
Also remember that mosins like different surplus ammo, so buy several types to try out. Hungarian heavy ball is dead-on in my m44, chezh light ball (green steel case, silver tip) chambers and extracts well but isn't nearly as accurate. Russian surplus from the 1980's (copper washed steel case, red sealant, no paint tip) is probably the best, but costs more.
