Winchester Mdl 70 Long Action Suggestions

I inherited a Pre 64 Winchester Model 70 chambered in 6mm-06 from a friends estate several years ago. I originally put the rifle up for sale along with most of his estate.

It didn't seem to get any interest until I mentioned it to a coworker. He wanted to shoot it before buying. We met up at the range and got set up to put a few rounds down range at 25 yards to check the zero. I shot the first shot and it was dead nuts. We moved the target out to 100 yards and he fired the second shot. It went practically in the same hole. I'm sure everyone is going sure that was a fluke or just a lucky shot. We thought the same thing. Just for giggles we moved the target out to 200 yards. Another co worker wanted to take the third shot. The look on our faces when we inspected the target and saw all three holes touching I still have the target! (a photo uploaded for proof)

It goes without saying that he was sold and was ready to buy the rifle for the full asking price. As usual I asked for his drivers license to make a copy and fill out the bill of sale. That's when I realized that we had a problem. He was an Ohio resident, and the transfer had to go through an FFL in OH. He refused to complete the sale. I wasn't upset about it at all and happily kept the rifle.

Unfortunately I am running low on the wildcat handloads (came with the rifle) and do not have the load data to make more. Wildcats really don't interest me so I don't really want to work up the load.

So here's the question. I am thinking about having the rifle re-barreled. What caliber would everyone suggest. I want something with longer legs then a .308 Win that will make sense in a long action rifle.

6mm-06 is pretty easy to form from 25-06 brass, only takes one pass through the sizing die, if you have the die. If you decide to rebarrel, any cartridge that has the 30-06 as it's parent cartridge will work.
.25-06
6.5-06
.270
.280
.30-06
.35 Whelen
or any "Improved" version of these will work. Pick your poison.

The problem I have with loading 6mm-06 isn't forming the brass. I don't have any idea what powder was used. No one seems to have load data. I wouldn't know where to start

Also from what I have read 6mm-06 has a tendency to burn out the barrel throat fairly quickly.

If those 3 shots happened as you say(25, 100, and 200yds by 3 different guys), I'd be researching and learning what to load it with. You sir have a jewel there and it was an omen that the sale didn't work out. If I had a rifle that shot like that...especially an inherited one...no way would I get rid of it or rebarrel it until it absolutely needed it. There has to be data out there.

6.5 o6 load data can be found in the Hornady 7th edition. They indicate imr 4350 h 4350 h4831 and n-165 for heavier Hornady bullets (129-140gr)
I would leave that one alone if it were mine.

How many of the original handloads do you have left? I'll bet if you pulled some of them down, measured all of the components and checked the powder type and flash rate you could get really close. Throw a few original and new loads through a chrono and you could dial it in.

For as infrequently as you sound to shoot it, keep it as a treasured remembrance and enjoy the accuracy.

Looks like a 'few' people have been having decent luck with RL22. Along with IMR 7828 and 4831, H1000, H4831.

From what I'm reading, the .240 Weatherby load data can be used as a starting point as the capacity is quite close, reduce by 5%. http://www.rifleshootermag.com/ammo/...ildcat_200808/

If you decide to break it up and re-barrel, I would be interested in the take off if you want to sell it.
