Youíre definitely right on with the tee shirts. LOL
I do have the above rig that does a fair job out quite a ways. It's a Sendero in 7mag topped with a 6.5 x 24 AO Burris. It holds a nice group just under 2" @ 300 yds with the Hornady 162gr BTSP's. Only problem is it isn't something you really want to do any quick shots with. Been there done that. Still got three but it was pretty hard. The little compact is just right to chunk in the truck and carry up to the country and if we head into the woods it does a GREAT job on moving critters as well as some which are just to dumb to run.
I just have come to grab the little guy during quick trips to the place. At 6.75# it is a dream to tote and being so short it goes through the woods on the rack on the 4 wheeler with no worries about vines and limbs.
I am working on putting away enough to talk Mr. Kirby into, or out of, one of his nice rigs myself. It might be in .270 or maybe something a little bigger. Definitely going to have a brake, and the grandson already has his own shooting protection. Got that for him last year right before hunting season.
As for distances, well our place you might be able to squeak out 600 yds on something but it would be hard. Now my friendís place, heck you can stretch one out about as far as you can positively identify what it is youíre shooting at. They have 1500 acres with about 800 of it being cotton fields. Not sure just how far would be far enough but, it is already interesting at times when we catch a pack of hogs out there in the open. Plenty of practice goes on I "gar on teee".
Our range has targets out to a measured 300 yds, and is well used most of the time. This year however, I haven't been able to get much done for trying to pay down some of our overhead. Once we get back to a manageable level again, the loads will be worked up and things will hopefully be back in perspective for fall.
