The ranges where I will be shooting are about 300-500' higher than where I live, and when you add realistic air variables (less barometric pressure, need to read how that plays in), I think I was ~800fps @ 1000yd. So my plan is to step build - build a 600-800yd Grendel, still wanting to stay with a 16" barrel (I really like the size) and then when I become proficient at which I am supersonic at, move up to a 6.5Creedmoor. Figure it is the most cost effective way to get to 1000-1200yd being I would buy the optic for 1200yd or so, and on the reloading size, I can cross-pollinate bullets and primers, using Lapua Small Rifle 6.5Creedmoor brass. Trying to do this as cost effective as possible. I also have to remember that in the summer in Phx, AZ, we will stay no lower than 90F+ 24/7, so some people have a 'No Shooting in the winter, here it is limited shooting in the summer, as soon as the range opens".
Now, that I am going down 2-400yds, would a Faxon, BA Hanson or Green Mountain Barrel be adequate? Thanks all for the input and giving real world realities.
Bob:
Depends on the target size. If you are shooting a five minute target, I am sure going cheap on a barrel will be just fine. If you expect to hold under two minutes all of the time (given you are one of those two minutes), you need to buy a top end barrel, a top end sighting system and a top end trigger.
If you are serious about long range shooting (600 and beyond), get a 6.5 Creedmoor, 6.5 X 47 Lapua, or one of the 6mm variants of each cartridge.
