I'm back to playing with a 6.5 CM again. Why, I don't know but I got a great deal on a PR barrel for my Savage so I figured why not. Maybe this time I'll see what all the fuss is about. Being a dedicated 7mm guy, I figured there had to be something about all these 6.5's because I keep hearing so much about them. And now that's all I can find on the shelves both in loaded ammo and in components...
anyway, after spending a few days loading and shooting I guess I just don't get it. 2700 fps. with factory 127 Barnes LRX ammo, and the same with a variety of 129-130 grain hand loads. Looking at the load data, I can't even expect much more than that from the dainty little CM.
So, I start thinking about having this barrel rechambered to 6.5 PRC. When I look up the load data for that cartridge, I'm not impressed by it either. Nor am I all that impressed with the 6.5-284 that is supposed to be such a great "long range" cartridge (although I guess the PRC is supposed to replace it?). So what gives?
I learned a while back that the larger the bore for the case, the faster you can push a bullet from it. So trying to push 140's out of a 6.5 bore at 2800 is darn tough while it is routine out of 7mm's and pedestrian out of .308 bores. Sure, you give up BC (in the case of the .308 at least) but you're also pushing it 200 fps faster from the same case.
All this has me struggling to decide what to do with this Proof Research 6.5 CM barrel. Sure, there is a whole shelf full of factory ammo for it in every store, but it does nothing my 7mm-08's or .284 win's didn't do better as far as I can tell.
I mean, the recoil is a hair less but not enough less to make me reach for it over my 7mm-08 or .308.
What am I missing?
