Shorten each end about an inch and you will be good for another 800 or so.
No downtime that way. No worries.
John is right about picking the 6.5 x 284. Can't dispute the fact that it wins. The new 7mm's are still in the experimentation stage. Under the right conditions they will shoot inside a 6.5. However the 6.5 is very good at all long ranges, 300 and up.
The 7mm has to beat the 6.5's. Until it does so consistantly the 6.5 will remain the King.
The other consideration you should have though is saddle time. Until you can read the wind, and what it does to your bullets, the most accurate rifle in the world won't make a winner. Sure helps though.
The two barrel thing is a great idea... chamber them at the same time, use one until you see the groups opening up and you cann't adjust for it any further, screw on the second and have the first set back... many of us do this... two barrels gobbles up a good portion of a grand... say 335 each and 150-200 to chamber each... if you can get another 700-800 rounds from the set back I think that's not bad for the cost of the chamber job... depends on the barrel but I think most match types barrels would do it.
7's seem to be doing good but there's more recoil, more power, heavier bullet and I dunno if I'd like the pounding for a day's shooting in a match if you did 4 yardages and sometimes it happens at 2/15 that's 66 shots/day... maybe... but for a first up long range gun I'd go with the flow, learn it and after that point think of a 7mm...
Jerry mentions 6mm and indeed they are an option... I used a 6/250 with 107s & 105s for a season. You could free-recoil that rifle nicely... but I found I was given up more than I liked to the 6.5s with the 1/3 less bullet weight... and I'm still learning to read wind/mirage, so when you don't get it right you've got no wiggle room on your shot... you'd better judge it pretty good... I found the 6/250 less pressured up than a 6BR, which I also shot in a tubb gun... but I was never happy with that...
with the 115 Tubb bullets out be interesting to see how well they work...
I know in the US they use them, but I think it's mostly for XTC shooting, with some dabbling in f-class...
if you go lighter, you'll certianly have to learn the wind at the longer distances, might force you to work harder in it and maybe get some good results... it's an option...
still first gun... I'd do the 6.5x284 and get on with it...
I get a lotta 1000 yard shooting in if most of your shooting is say between 300/600 yards... you could go lighter... and take your chances at 1000 when you shoot it...
just remember if you shooting the longer distances that's where the seperation occurs in shooters based on ability to judge the wind or what's going on out in front of you... you need it all working to keep up... there's no free lunch!
