bigbore4166.5-06 imp. or not
do the gains in velocity and case life outweigh the higher cost of the improved version's loading dies over the "standard" version of this round? also, what is the correct way to form cases for either of the two rounds, in particular the improved round? e-mail address has changed to skippy091953@aol.com. many thanks, victor e.

flinter6I gotta 6.5/06. Dont think it can be improved.
Shoots the lites outta any thing I care to hit.
Why waste money?
BTW I use .270 brass , life the longer neck.
One pass operation, Then trim.
Either way you'll love 6.5s
[ 07-28-2003, 06:26: Message edited by: flinter6 ]Mine was improved when I got it,..so I can't say anything about original velocity. I do know they shoot well,.....and fast.
Mine was getting sub .5moa fireforming the brass (lapua)

larrysMine also came improved when I got it. I don't know that the improved is that much of an improvement, but it sure is fun to shoot. I also use 270 brass. It is no big deal to fireform. Mine gets 3/4" on first fireform and 1/2" or less after.

micmacI'm not sure how much improving will help, but the 6.5-06 being a wildcat anyway, why not go with the improved. Your going to have to fire-form brass anyway, and the dies aren't going to be a big deal either way. Why not get that extra few FPS? If you were going to be practical(which isn't any fun) you'd get a 25-06.

StonecreekI've got to agree with Micmac. If you're going wildcat, why not do it "right" (not that there is anything particularly wrong with the standard 6.5-06). I would suggest that there is no need to stay with the usual Ackley improvement since there is no factory ammunition (except for some expensive proprietary ammunition, I think) to fire in the chamber anyway. A longer case body with a neck of about a quarter inch in length would provide you with a measurable increase in powder capacity over the standard 6.5-06 and would give you at least a small edge in velocity, all things being equal.
The 25-06 in it's best day will not measure up to the 6.5 -06.just my .02

CedarmtmikeI've had both,6.5-06 on a commercial FN and an improved on an O3A3. Both shot great, both functioned flawlessly, and I got rid of the mauser. Hey, if your going weird, go all out. And you do gain a little velocity. WAY better than any 25-06 I've had.
BB416, the gain in velocity between the two would probably be minimal. However the case life of the Ackley Improved version would probably be longer due to case design. I like to neck up cases to prevent someone from accidentally chambering them in the caliber on the headstamp. That means I'd use 25-06 brass for the 6.5-06. As far as fireforming just pick a heavy bullet load with a relatively fast powder from one of the reloading manuals and use this to fireform. Any load for the standard 6.5-06 should be safe in the improved version. Watch your rate of twist in this caliber as .264 bullets are long for their weight and if your going to be shooting heavy bullets you'll need a fast rate of twist. Have you checked out the 6.5 WSM yet? What action are you going to use? Hope this helps some. Paul.
