RE: 6.5 x 55 Swede.... I'm weakening
I have a new CZ 550 in 6.5 Swede. Rings/mounts came with the rifle at no extra charge. The gun is really nice, pretty wood & metal, hand lapped 24" barrel, and the action has pillar blocks to clamp into the trigger guard. This caliber is inherently very accurate, adn this rifle groups factory loads right around an inch and often less (5 shots @00yds.) This is better than I am used to from most of my scoped rifles.
I also have two M38 Swedish Mausers, one left original military and one that I dropped into a sporter stock with no other mods. Both are far more accurate with open sights than my other military rifles that I own; they shoot better than I can.
The 6.5 mm bullets are great performers too. They penetrate rather deeply even at the lower velocities that the Swede yields due to the high sectional density. The first time I saw a 6.5x55 cartridge I thought, "Man, what a long, skinny bullet." This tends to make them very stable in flight.
I have only run 50 rounds through my new CZ and can't wait to see what it will do with an optimized handload.
