Tikka Question

[MikeG77]

I just bought a Tikka M595 in .243 Win. I can't seem to find the twist. Does anyone know what it might be? And what's the heaviest bullet I can use?
Thanks
Mike

Looks like they put on a 10 twist barrel, unfortunately. I didn't look at a twist calculator but I think you'd be able to stabilize some of the 90 grain bullets. You'll want to check that though with the bullet manufacturer

This ^^^ right here is your friend. I bought a Tikka 243 with 10tw last yr for a couple kids. It shoots 90 gr ballistic tips well to 500, farthest I tested.
Your elevation, velocities play hard in stabilization, If I was to handload for them, I am positive I could get a Berger 95gr classic hunter to shoot, here at my elevation.

Hi Mike
As noted above they are 1:10" twist

In theory a 100 grain should be ok but I would start with a flat base to keep the length down. 100 grain is the minimum legal weight for larger Deer species in Scotland so they are used quite a lot in .243 over here.
If it will not shoot 100 grain flat base then I suggest the 85 grain Sierra HPBT. A very popular Deer bullet in England where the Law is different

For rifles chambered in 6mm cartridges, the #1530 85 grain hollow point boat tail bullet has proven to be highly effective on medium game, such as deer and antelope, and it is outstanding in this application. It is one of the best all-around bullets for rifles chambered in 6mm Remington or 243...

You will at least have fun trying to find a load.

PS. The Tikka 595 is a really sweet little rifle. The bolt is as slick as a greased weasel. Very popular in UK.
