Sako by all means. Got into them decades ago. Hard to beat. If I use a particular caliber, there will usually be a Sake in the bunch. Unless it's. 308, then there will be more. Large or small!! 375HH to .22.
Favorite in 10mm has to be the CZ Dan Wesson, 1911 SS target. They may be called the Sportsman. However I didn't see one below $1K even when they hit the market. Probably well over 2K now, but I'd rather have this than a case of Glocks.
I have set up my bags at the end of the den and sighted on a brass doorknob at the end of the kitchen. I do like the humor of the neighbor's window though!
If you can't do the 70% on 12" steel at 600 yd, you aren't allowed to climb on the 1,000 yd platform. Then you have to take the chief's $500 course and try again.
Alas, I do have a beautiful low-wall but any ammo is expensive and no 25gr. There is still 500 rounds on my shelf thankfully. As others have noted, you probably wont get under 1" group. I have no idea how many exist, just had to have it.
