Wow, thanks for the detailed and thoughtful responses.
Thanks for the ballistics chart Runco, that does a great job of helping me visualize things. I'm going to look that up in some of the other sizes mentioned!
Sorry if my post was confusing for some, I appreciate the help. By "Long Range" I meant around 200 yds. Getting much beyond that will be hard even at a good range, and as I said, I'm not a hunter, so don't_really_ need to target game out beyond that. That being said, I want to acquire the firearm and become proficient at it should the need ever arise... Be it 4-legged or not. I do want to be able to impart significant energy at that distance and put the target into the dirt with the first round, hence why I was leaning to the larger size. Being a very common size, I also anticipate availability to be good across the spectrum of bulk rounds, hi-quality, reloading, etc. HOWEVER if I can get similar results from a smaller round, w/ less recoil, cheap lead, and equally 'available', then I'd certainly consider it, as the Total-Cost-Of-Ownership for such rifle will be much less... and frankly, I hope I never HAVE to use the thing (just want to be prepared in the event).
We are also looking at farmland/homesteads in rural settings, and I anticipate run-ins w/ Local Fauna inspecting our livestock, crops, and like issue's, so effectiveness will trump cost benefits. But lets face it, most of the lead is going to end up in the dirt-pile behind an iron-target in the back corner of my lot.
I don't really have a budget per se, but I don't need to impress anyone at the range, and obviously don't have the skill to warrant a $1500 rifle. I've been looking at the M1A, the Ruger American Rifle, and Remington's. I have a Mossberg Shotgun I'm less-than-impressed with. Frankly I'd rather a used Remmy than a new off-brand after that experience.
Admittedly I find the array of rounds confusing... I simply don't have enough experience nor know enough to select between them all (that chart really helped, though I think I like the 300 WinMag!) Is there a big difference between the various .30- rounds? Growing up in the NE I knew lots of people that hunted deer w/ 30-06 and 12-ga. slugs, but not many would attempt 200 yd. shots. Having sat in a few fields thinking about what I want this gun to do, I'd like to be able to try 300-500 yd. shots... but wouldn't expect to do it often.
So good knockdown power and trajectory out to 500 yds would be about the maximum? Affordable, common, easy to find/trade, etc. I was quite surprised at the situation that's come up w/ .22's. That's one reason I'm searching for a highly available round to build a rifle around. What about the various styles of bullet? Would a hollow-point of a smaller round be as effective as FMJ of a larger since more of the energy is absorbed by the target? I've heard some great things of the .243/.270's
What's the difference between a .308 and 300 WinMag? Bigger bang and a slightly smaller bullet = flatter trajectory?
Do the longer barrels increase accuracy significantly, or does the extra weight make aiming that much more difficult? A friend had a nice Stainless Steel Barrel rifle that he let me shoot that was very nice, but I found the regular steel easier to shoot, as the stainless was too light? However they were both short-barrels. I would like more than an 18", but don't know if I should be searching for 24"?
I was very grateful to John @ Fighting Sheep Dog and the folks at Windrock Shooting range for their Range-Day w/ the AR's last month. Was a great time, a lot of fun, and I learned a lot. Got to try a bunch of AR builds, including a 300-Blackout model. Nothing like a few boxes of ammo to decide if something's for you? Anyone w/ an M1A or a Ruger and some space, care to let me buy you some ammunition in the Kingston/Knoxville area, please drop me a line! No, that's not me in the avatar....
Thanks again!
