The "what caliber" thread.......

[Bily Lovec]

personally,
I think you should stop while you still have a shadow of credibility left.

I understand what you are saying. There can and is a lot of differences when you consider different loads, bullets, barrel lengths etc.... I was just comparing the same bullet (although one is slightly, 10gr, heavier). I was just using the calculator and bullet choices given.

I also understand that the vast majority of folk don't shoot 300-500 yards so it's really a moot point really.

It's just, again, IMHO that the .308 isn't all that special. Especially for those who are speed freaks like myself.

I understand you're limited to what's available on the calculator, but those similar weight bullets are FAR from similar performance wise. You're looking at a middle weight .277 bullet with a moderately sectional density, and what most would consider a light weight 308 bullet with crap for SD. At range, the heavier (for caliber) bullets are where it's at. Compare a 165 class 308 to your 140 class 270 and you get way closer. Don't get me wrong, I'm not loving 30 calibers anymore, but they work, it's just hard to get enough weight behind them, imo, to get a good BC and maintain a good velocity without beating yourself up with recoil. From now on, I'll be buying/building 7mm and 6.5mm rifles. If you can get a 7mm bullet in the 160-170gr range, running similar velocities to a same weight bullet in a 308 sized case, you're head and shoulders above the 308 strictly because of the available BC of the 7mm bullet. To get similar BC in a 30 cal, you have to get over 200gr, which will hit like a hammer, but a 308 case just doesn't have enough boiler room to get it up to an acceptable velocity IMO. Start looking at those heavies in a 300WM, and you're back to where you want to be, but again, heavy recoil, and can still be beaten with a heavy 7mm with a magnum case capacity, starting faster and same or higher BC.

All that said, INSIDE AVERAGE TO EVEN SLIGHTLY EXTENDED HUNTING RANGES (0-400 yards), the differences are negligible and don't make any difference at all, especially on whitetail sized critters.

I understand what you're saying but if that's the case....... Why are SO many ALWAYS for sale

I've seen a lot of "Stic" knives for sale too, so what are you getting at?
