243AI is a 700/Hart/1 in 9 twist/70 grain BT's, Leupold 6-18 vari-x 2 with turrets. The 22-250 is a Model 70, Hart, 50 grain b-tips, Nikon. The 220 Swift is (gasp) :-[ an old Arisaka with a 1950's Douglas, 17lb, walnut stocked icon of the early years. It has a (gasp) :-\ 1979 Weaver T-10. 40 grains H380, 55 V-Max. It has recorded kills to 600 yards. I know, it is shocking, but the old story "beware the man with one gun" applies here. Great thing is any shot over 200 the weight allows for the shooter to see the hit. Rangefinders are Leica and Bushnell, tables are Harts, tripods are Ultimate tripods, rests are HArts and Bald Eagle. Spotting scope is Nikon, bino's are Big Eyes. Most work done by Hart. A 40XB was recently sold to fund a motor for a classic car.
This shoot the 243AI really shined. At distance, those 70's make a big difference on grown chucks.
We have been shooting this farm with these and similar guns for about 12 years. We hit this farm about two times a year, two years in a row, then hunt it hard the third year (to make the farmer happy). This allows us to get high numbers per day for two years, while making it look like we are making a huge effort to reduce the numbers. ;D Then the third year we hit it and really take care of the edges, leaving some to rebuild the "shooting field". I have never encountered a place like this, and every time I go there I am amazed at God's blessing to me. The first time we hit high numbers, we left and there were about a dozen chucks still standing in parts of the farm we could not easily shoot. Crazy! The farmer only allows us on, based on our background in shooting instruction/safety. it is a remarkable situation.
Nearby there is another farm that requires us to shoot across a valley where the closest dirt it 625. Our numbers are lower there, but we have confirmed kills to just over 830 yards, mostly with 243AI 8twist, heavy bullets, or 7mm's. If I did not have these farms to shoot, I would likely quit this game.
