I have an FN SPR action with a .308 bolt face and large claw extractor. I was wondering if it is possible to modify this bolt to accommodate a .223 bolt face or if it would be worth the hassle. This is basically a Winchester Model 70 action. Thanks.

I was looking at the 20BR, but I think it is a little overbore with extra barrel heat for prairie dog hunting. I was also looking at the 220 Russian necked down to 20 caliber without any other changes (I think 20 Beggs). I think the 220 Russian case will work with the claw extractor on my bolt face.
The 220 Russian is the case that the 6ppc and 22ppc are based off of.
RSo, this may be a silly question because I'm not a pdog hunter. But, why do you want to shoot a tiny little bullet with a poor bc.
Why not a 6br with a 107 SMK that's going to shoot dead nuts accurate for thousands of rounds? Do people use 6br for pdogs?
With coyotes, I suppose you could make the argument that you prefer "flatter" trajectory because there may not be time to range and dope the wind.

For prairie dog hunting there are a lot of resons to shoot a light bullet. Velocity is the name of the game when you want to vaporize the dogs. A varmint bullet going 3800 to 4000 fps seconds turns the dogs into a red mist. The recoil is light enough to allow spotting your own shots and you have about 100 yards to 400 yards of place it on them and shoot without adjusting elevation. Also, you can go through 100 rounds in very little time when the babies come out. The small rounds produce little barrel heat and let you shoot longer. Reduced muzzle blast keeps the prairie dogs up longer and at closer ranges. The majority of shots are less than 500 yards with most between 200 and 300 so the need for high bc bullet is not there. I do use my 243 Ackley and even my 7mm Dakota for dogs way out there, but that is not nearly the same amount of shooting. I also use a 17 pee wee for dogs under 200 yards.
