Wow, there is a load of BS being spread in this thread. Don't get me wrong, there is some good info too. Apparently magnums are the best for shooting out to 1k? That's news to me... I guess I should sell my .260 then. What about all of the f-classers using 223's, 308's, etc?... Does ballistic coefficient mean anything at all? There was a comment also made about having a variety of bullets (110gr. 30 cal bullets)... I am sure those are ideal for long range.....
To the original poster, read carefully and review information from more than one source. Your Savage 223 can shoot out to 1K if it has the correct twist rate to launch the heavier vld bullets. If not, you can easily get it rebarreled for under $500, installed, to throw the heavy boys. Next, you will need optics up to the task. I am a fan of high magnification but more importantly is the internal adjustment limitations and how well the scope tracks.
There is plenty of good info on this forum but you need to search. There are a ton of shooters that shoot to 1000 and beyond without the use of magnum cartridges. I would listen to the regular f-class shooters. They know their stuff.
Yes there is a great deal of BS flying around. The regular competitive F-Class shooters will give you the most acurate info. There's a big difference between reading about long range shooting, and those that get their information through experience. Be careful where you get your info...
Lots of calibers will do very well at long range. The 223's can work, but you really need to steer them well. The 6mm br, 6mm Dasher, 6.5x47, 260, 6.5x284 do very well at long range. Infact, world records are still being broken with the tiny 6mmbr and the 6mm Dasher. The 284, Shehane are very good, and the small magnum's work well. With the short magnum's though, experience is a plus as they need some tuning, and with short barrel life tuning is done often. Managing recoil and how to deal with it is paramount to shooting tight groups.
If you have less experience, i would shoot a 6mmbr,6mmDasher, or a 260, 6.5x47. They are easy to load for, very easy to tune and will teach you alot about shooting long range and wind reading. And on a no wind day, look out they will shoot bug holes that none of the bigger calibers will ever do..
Just talking from my experience, have fun!!!
