Im hearing a lot of folks for the classic standbys, the 308 and the 30-06. Also Lots of 6.5, quite a few 284 win and a few 7-08. I have 2 308 wins. Amongst these other 3 (6.5x47, 284 win, and 7-08) what are the pros and cons? Barrel life, ease of loading, ability to mag feed in a short action?
the 6.5x47 and the 6.5 Creedmoor are the ballistic twins of the 260Remington. They have some features that some like over the other two with regard to brass but performance wise they are effectively triplets. (the 6.5x47 may have a slightly lower capacity) Take a look at the available brass for reloading and in the event you ever did want to find off the shelf ammo there will be almost none except for the 260.
284Win What bullet do you want to shoot? If you keep to the 140s and lighter I would think that mag loading will be fine. DannyBiggs is probably one of the most knowledgeable people out there about this caliber, he posted earlier in this thread.
7-08, probably the longest barrel life of the group but none of the calibers you are looking at are barrel burners. If you are not target shooting you'll never wear one out. If you are target shooting, then none of these is a barrel burner and for a target shooter barrels are a consumable so you plan on a replacement at least every couple of yrs unless you are running one of the barrel burner calibers (like 6.5-284) then it's every yr (or more often)
Ballistically the 284Win has the biggest boiler and will give you the highest velocity, high velocity always comes at a price (nothing is free). (recoil, more powder and some barrel wear compared to the other two) The 6.5s or a 260 will probably get you a bit better ballistics than the 7-08 if you can feed heavy for class bullets.
I looked at three cartridges to build a new hunting rifle to replace my hunting 308 two yrs ago. Like you the choice was in some ways influenced by what was already in the safe. I already own a 7mmRM, so I didn't feel I need a short mag of any variety, I've got a magnum that never gets used now, and I wanted something that shot a little flatter than the 308.
I didn't go with the 284Win, though I really wanted one, I still really like the caliber but to me, as a hunting rifle it seems to occupy a niche that I just don't need filled. It seems more of a Magnum Lite, and if I needed that I have the 7mmRM. I thought long and hard about the 260Rem, but in the end I went with a 7-08, not so much for barrel life, I'll never wear out the barrel in a hunting rifle, but for the option of a little heavier bullet, but not heavy for class, running the 140 class vs what is available to the 260s in the mid weight range.
That's my thoughts. You need to look at the ballisti
