I see a lot of great ideas on this thread. As a provisional game, I think the match director could implement any additional divisions as needed to make things fun and fair for the competitors (assuming enough people show up to shoot).
With that in mind, at 300, caliber almost doesn't matter. At 600, the ballistic advantages would definitely be there, but the large target face would absorb some of the advantage.
In the end, I think the best marksman will win regardless of caliber - we figured out in F-open that wind drift (within reason) has less to do with score than we believed.
I happen to know that there was some idea of this back a few years ago. John Dink created something like this using an F-class target. I'll admit that this isn't the same thing; however, some of the data does apply.
Using a 20" barrel with mag fed 77gr (honestly fed from magazine), my high score is a 385/400 at 600y. (Two strings of 20). Put me on a high-power target
So is this saying i can put a 12x scope on my all out compass lake service rifle, rig up a harris bipod and compete with it?
Yup. I know a good CL
Im in if i run across a match then. Wont take but a min to get my gun ready. The shelf built ARs dont stand a chance if they allow guns like that
Agreed.
By eliminating the allowance of
Do you think this class of gun could really compete with an f/tr gun or better yet a marginal f-open gun on a machine rest? The scope alone is a handicap not to mention no proper rear bag or sled bipod or 90gr bullets.
Locally, we've been running a class like this for years. Our local class is for 223 only, we restrict to magazine length ammo, and while we dont restrict barrel length, several of us are running 20" barrels. That said, we are using folding bipods, 40x optics and rabbit ear bags. My average at 600y is in the 380s/400, and we are really windy here. F/tr (always 308) is usually a few points ahead of us in same conditions, but wind skills can change that.
In my opinion, given the restrictions this should quickly be an X-ring game. I don't see restriction to magazine or SAAMI ammo, which means the shooter who handloads will win. Locally we've had many shooters, never have we found factory ammo competitive at 600y, but I'll assume it's possible to have a rifle that will; it'll be a no-go vs a handloaded 80gr single fed.
Locally, keeping ammo to 2.260" or less has kept it interesting. We've got our #1 who uses a Sinclair bipod, 77OTM, and has very good wind practice. Occasionally we'll have an upset by someone shooting a 69/70gr, so I see a 1:9, 1:8, 1:7 all competitive. Given the NRA rules, I'll be loading 80s for sure since I no longer have the rabbit ear bag, and only 12x.
Or move to a different caliber. 308 might be unruly with the weight restriction, but 6mmAR should do nicely. Maybe even 6.5 Grendel.
