I don't think that you'll gain much over the 6.5-06 or its Ackley version due to it already being overbore capacity. Unless your going with a 28" or longer barrel I think that the standard 6.5-06 would be a great choice.
Just neck some good 30-06 brass down and go its a one step deal and Lapua makes 30-06 brass.
JD - long range (500 plus ) varmint , pronghorn and deer.been looking at all the 06 based cartridges - Gibbs, Ackley , Hawk etc.I have a long 700 action - 28" #6 and vias break. I figured the longer stronger case would help performance.problem is I have a 6.5x284 being built as we speak - same set up .thanks
Old Fart, building a 6.5-06 right now. Decided to go this route because the AI and GIBBS don't feed well from some actions. Depending on the barrel, you can get more vel from the improved cases but accuracy may not be there.
My goal is to get 2900 to 3000fps from the 140gr SST out of a 24" barrel. Should be possible and that would be enough to hunt to 650yds or so or plink as far as my scope will allow.
I have played with a 30Gibbs and really liked the performance. If you are willing to put up with the extra case forming and possible stiff feeding, they are a bunch of fun and can give you another 100 to 150fps.
Jerry - nice to hear from you - I'm still throwing this around , I have a 6.5x284 being built as we speek , but just can't get this 06 thing out of my mind , but like you , I'd rather shoot than make cases sooooo. I 'm going to sit on this for awhile and get things ready for the things I've got working right now - a 6.5x284 and my 338 win thats being rebarreled- see ya
IMHO, I'd stick with the 6.5-284 for a while. It should give 2,950 - 3,000 without a thought...+ you have an excellent database of loads & info. Add to that better, commercial, READY-TO-GO cases and you get a combo that's tough to beat inside 1K. [img]images/icons/wink.gif[/img]
