Cartridge/caliber size and fun, plus Tikka action with 55-57 mm cases.

The 6.5 Swede in a tikka just seems right. Keep it Nordic

I’d build a wildcat 6.5x55 if someone else here did all the leg work lol. I don’t want to buy reamers and custom dies. There have been some done in the past, the 224&6mm Vais, and 22&6mm addiction. Both were blown out and had 35 degree shoulders I think. Lapua brass is $1 a piece. I’m tempted to buy a few hundred pieces before it’s all gone and price goes up. Imagine those cases would outperform the creed/308s buy a good bit. The 6mm case is a great one too but brass is the limiting factor there.

I have. It is another tempting option that is clost to ideal for a Tikka action.

That's why I flagged it since you were talking about maximizing 6.5 and 7mm calibers on a tikka action with a standard bolt face. Plus you were talking about changing the shoulder angle, etc. which a 284based case already has inherently.

It would be hard to beat a 6mm Remington in the Tikka action for performance and accuracy with minimal recoil. Hornady brass is easy to find as well in 6mm Remington. It's the 7x57 Mauser necked down to 257 Roberts necked down to 6mm Remington. Pure perfection in its lineage!

That is very interesting. How is velocity in 18-20 inch barrels?

Certainly another to add to my list. Sounds like a nice spot between a 243 and a 6 UM.

My son has it now after it was my first big game rifle which is a Remington Model 600 with an 18 1/2" barrel. In this rifle we shoot 100 gr. Nosler Partitions using IMR4350. There might be powders that would even give you a bit more velocity in this rifle, but it shoots well and works great on game. I chronographed it at 2800 fps even.

Same exact load in his Ruger MKII in 6mm Remington with the 22" barrel, the 100 gr. Partition chronographs at 3000 fps.

Same load and bullet in my Ruger 1B with it's 26" barrel in 6mm Remington chronographs at 3140 fps.

Here's a torture test at 25 yards with Partitions, E-tips, and Accubonds out of my Ruger 1B 6mm Remington.

My next build is going to be a 6mm GT, perhaps on a UM Raven. Same ratio of case capacity/bore area as 6.5 CM (1% larger).
