We were deer hunting, but the general rule is to shoot every coyote on sight. At about 7:30, one got across the gas line on my weak side before I could get shifted. Two showed up at 9:30 and stayed a might too long. Rifle is I sighted in at 200. I estimated a long 200, so I centered his shoulder and went through the BRASS.
This is a rifle that my dad gave to me when I was in high school and starting to get out and varmint and deer hunt with friends and on my own. It started life as a 243. It was my only high powered rifle till I was married with kids of my own.
My son will be 20 in January. He is in college, making great grades while holding down an almost full time job and full time girl friend

. So, my plan is to have this rifle gone over and give it to him as he's now a man and needs a good deer rifle. He has a 6BR competition and varmint rifle. So, I had this done in a straight deer cartridge. Having read a whole lot of Jim Carmichael growing up, a settled on a straight 260 Remington after briefly wrestling with the idea of a 260 30 deg improved.
He will get everything that he needs from brass through bore guide and a cleaning rod for Christmas. The only thing that he won't have is his own press as the bench doesn't have room for another.
To answer your specific questions, the barrel is 23.5" from the receiver to crown and I'm not sure about the velocity. The load is straight from the new Berger manual. I haven't had time to work up anything special. Mike did this one for me on the fly when I picked it up Wed on the way down to my home town.
This was my parting hunt with the old girl. I killed a several deer and a truckload of groundhogs and crows with her. She's now all remodeled and moving on to the next generation. I'd have liked to have gotten a deer, but the one buck that I saw wasn't quite a shooter. He'll be a nice one in a year or two. So, the big dog yote will have to do.
Now, the question is what to build for myself....
