My brother-in-law has a M77 MkII in .30-06 and it is a good rifle. The CZ 550 series is a good copy of Mauser features with some upgrades. CZ has recently released the new CZ 557 that does not have the single set trigger, but you can work the bolt with the safety engaged. There is always the classic Winchester Model 70 as America's Mauser 98 copy, with modifications that bring it up to date. Ruger and CZ rifles come with factory scope rings, which makes them a good deal. Scope ring bases are integral to the receiver on CA and Ruger, which I like a lot.
CZ has the 6.5mm Swede chambering offered in their full stock Mannlicher style, as well as the American stock style. Winchester Model 70 is offered in 6.5mm Swede as well. Personally, I think the 7mm Mauser beats the 6.5 Swede, as the 6.5 Swede has the exact same powder capacity and was obviously a copy, as was the .30-06 Springfield. The US Government paid the Mauser brothers a royalty, but I wonder if the Swedes ever did. The 6.5mm Swede is actually a closer copy than the .30-06 Springfield. The 7x57mm Mauser was upgunned to the 7x64mm Brenneke for sportsmen, and a couple of decades later the Americans answered with the very similar .270 Winchester. The .30-06 was eventually shortened to the .308 Winchester, and Remington eventually made it a ballistic twin to the original 7mm Mauser by creating the 7mm-08 Remington......this brought the copycat war full circle to the original cartridge. And to make sure they covered their bases, Remington released the .280 Remington to duplicate 7x64mm Brenneke ballistics.
The 7mm Mauser is truly the father of the most useful American centerfire cartridges. And oh yes, Remington paid homage to the 6.5mm Swede with the .260 Remington, with similar ballistics in a short action.
My brother had a real 6.5mm Swede military rifle and the 6.5mm Swede is a good cartridge, but I'm sticking with the original 7mm Mauser. Imitation is the most sincere form of flattery, and it was the 7mm Mauser that was imitated. The Swedes decided to bore it down, and the Americans decided to bore it up, with a proportionate powder increase. Since the 6.5mm Swede was bored down without a powder reduction, it is a bit of a magnum and likes a somewhat slower powder than the 7mm Mauser or .30-06 Springfield.
The Winchester Model 70 in 7mm Mauser is not very good because the twist rate is too slow and the barrel is too short and they use the standard length action. Both the 6.5mm Swede and 7mm Mauser should have a barrel of at least 24" and the fast original military twist rates if using heavy bullets. If you slow the twist rates, you might as well buy a .260 Remington or 7mm-08 Remington. The .308 Win case handles the lighter bullets better and you get a lighter shorter action.
