Which Caliber?

I have a Winchester M70 Lightweight Carbine I purchased when I was 18, that was 24yrs ago. I am looking to re-barrel this rifle, I was thinking about sending it to Hart Barrels and have them put a new barrel on it. That had me thinking about changing caliber as well, with the M70 receiver, what would you guys recommend? I had thought about a 6.5-284, what would work for that receiver? I reload my own ammo, but I don't want to make my own brass, I would like to stay with something that is readily available on the market. I do not have a 30 caliber in my arsenal and do not have a 6.5 in my arsenal. Any thoughts out there that I could use with the receiver?

Thanks.

I will look at Peterson brass when I get my rifle back from the smith. 2855 is fast for a 26" barrel. Most guys I know are running about 2800-2850 with a Berger 180-184 gr bullet. I'm will be using H4350 or H4831sc both are slower powders compared to any of the RL powders. In F-class we shoot 22 shots in 20 minutes. The barrel gets very hot. Most of all if your rifle likes what your feeding it stick with it.

What are you going to use this rifle for, what kind of game and at what distances do you plan to hunt? Also a consideration that is oftentimes overlooked is availability and costs for components. Before you make a decision upon cartridges, I strongly urge you to do the research. Some brass, if you can find it, is going for more than a $1+ each.

I plan to use it for WT Deer, Hog and plinking. I had also planned to upgrade the stock as well, so this is going to be a semi custom job with Hart doing the Smith work. I already own a Custom 28 Nosler for the chance I go Elk hunting, I was mainly looking for a new "toy" to use for plinking and hunting. I enjoy shooting and really cannot with the 28 unless I want to re-barrel it each year. I also have a 7 Remington Mag in Ruger M77 Mark II that may get a new barrel as well, I may make that one a 30 Caliber, a 30-28 Nosler since I have 28 Brass. I am really leaning towards a 6.5 or 280AI, but I have always wanted something in a 6.5, a tack driver, I just don't know which one yet.
 
I highly recommend the 6.5x284 if you want a 6.5 that works on a standard long action. The new 6.5 RPM from Weatherby looks to be a good one too, but It might take a couple years for brass and things to start becoming available and widespread. The 6.5x284 has excellent brass from Lapua and ADG is developing it as well. It's a very accurate cartridge with a great case design as well. You can push 140s at 3000+ and the new 156 Berger can also get close to the same speeds as the 140 surprisingly.
 
The Ruger action wont make good 30-28 because of mag length. I Love my 30-28 with the 215 I havent got the load completely finished hope next week weather cooperating I can, i gotta test my loads at 500. My O.A.L is 3.65 +
If you can get a action with 3.7 mag box i strongly suggest a 30-28 with .225 freebore.

I would agree with almost everything you said and there is no doubt of the success of the 6.5/284. Where I disagree is with the "great case design". If it had a neck on it, it would be. A great case design would not burn a throat out as fast as it does with the bore/capacity ratio that it has. Just my 2 cents.

Baaed on what you mentioned you dont have in your arsenal I epuld go with a 300 Sherman so no need to change the bolt face, Elkaholic will correct me if I'm wrong.

I preffer 7mm or bigger for hunting large game that's why I recommend this and it sounds like you already have something in the .284 caliber. I believe the 300 sherman will give the best performance for a 30 cal in a long action without going to a Magnum option

These Sherman wildcats are very interesting, especially if I can form my own brass with a hydraulic die, however, I am not a Gunsmith and do not have a lathe. I see the 270 Sherman is very interesting as well since it looks like I can use my 270 brass to form the 270 Sherman.

Thats also a good option
 
We put together two .270 Shermans. They were super easy to make brass, neck up to 30 cal, and then run through a standard non bushing 7mm rem mag die without the expander ball, it sets the false shoulder perfectly and being that it's a standard die without the expander ball, set the inside neck diameter almost perfect at .270", so after running through a 30-06 expander ball, then a 7mm rem mag die without an expander ball, charge and seat bullets.

170 EOL from 2950-3050 depending on barrel, components, etc.
