Thanks for the thought!Aim small. miss small
Throating...once you've made the decision as to cartridge, tell whoever is chambering the barrel what bullet you'd like to shoot and tell him to throat the barrel for that bullet. For instance, in my 260, I asked my smith to throat the barrel for the 140SMK. This means he will set it up so that I can seat the base of the bullet right at the neck/shoulder junction in the case and the ogive of the bullet will be just off the lands.

lomsf24 also raises another good point. In your original post you mentioned a 1:9 twist, check the Berger website, they recommend 1:8 for their 140 grain bullets. Personally, I split the difference and will have 1:8.5 in my barrel.

    Trebark, Thanks for the input, very helpful. The rate of twist was a mental block. I was thinking of my 7mm barrels which are twisted at 1in 9 but I know that the twist for 6.5s are 1in 8. I appeciate the info on the throating issue. My intentions are to use the 140 grain berger VLD bullet, and because of the secant ogive,throating to me could be a issue, but I have had very good luck with standard chambers that did not need any modification to accmodate them at all.And with the 06 action, (by the way, it's a remington) there is ample room to seat the bullet out and still fit in the box if I chose to keep it. I might make it a single feeder, but may retain the magizine for hunting purposes. Boy have I learned a thing or two tonite!

    While you might have had good luck with standard chambers and VLDs it would be worth throating your barrel for the 140VLD as this will allow you to seat the bullet farther out which gives you more case capacity.

    Re: 6.5-06, or 6.5-284

    I always love these discussions.

    I've gone back and forth so many times myself, over this same logic path. So far, I bought a 700 L/A donor then re-committed it to a hog rifle (35 whelen, hammer from hell on hogs), and I am now having a full custom 260 built specifically for tactical match shooting. I chose the .260 because of its reputation for accuracy and personal recommendations of .260 shooters with nearly 3000 rounds of match shooting. In this particular rifle, barrel life is a consideration, but would not be an issue for a hunting rig. 25-06 is more overbore than 6.5-06, but you don't see a million posts about 25-06 being a barrel burner. Why - because the vast majority of 25-06 rifles are hunting rigs. If barrel life is truly an issue, buy 2 barrels at the same time and have the smith chamber both. Once the 1st wears out, swap to the 2nd and keep shooting. Compared to the cost of components it will require to actually burn up a barrel, the barrel & smithing cost of the 2nd barrel are not so bad.

    I think 25-06 brass loaded with a 6.5boattail and and fireformed into 6.5-06 improved is the way to go but I have not tried it myself (yet). The downside is limited choice of dies. Custom dies or RCBS dies may be the only choices. (if you know of other alternatives, speak up!!) A 6.5-06 improved should not chamber into a 25-06 rifle. Alternatively, you could buy 6.5-06 A-square brass and fireform it. Or just build a straight 6.5-06 and be done, except without the velocity boost of the larger case. Inch for inch of barrel length, the 6.5-06 beats the 6.5-284 velocity in all manuals. In those manuals listing equal velocity, its a 24" 6.5-06 barrel against a 26" 6.5-284.

    For a hunting gun, I suspect that a 6.5-06 improved with a 24" tube would be super nice. All the manuals list 6.5-06 data with a 24" barrel, so you could easily beat that data and no trimming. It would easily beat a 25-06 and a 270 as well. In fact, I was just recently inquiring about a 700ADL donor for that purpose. The old 80's era ADL's are a nice light rig with comfortable grip angle, smooth actions and well balanced.

    If anyone knows where I can find a L/A 700 ADL donor for under $350 please let me know!! Barrel can be rusted out - I just want the action & stock...

    Re: 6.5-06, or 6.5-284

    Hey Loadersloft, I get your drift and that too is food for thought again. I must say that I have even considered a .260 because of the recoil and barrel life issue. It would be a fun gun to shoot that could be shot and cleaned all day without AS much issue with wearing out the barrel. And with the smoking high BC of the BERGER VLD, accuracy should be awesome, and DEFINATELY capable off some LR deer hunting as well. My objective on this build is actually two-fold. One is a rifle to shot and to hotrod with highpower optics to enable long range shooting, of either targets or whitetail. has anybody had experienc with the 6.5 Credmore? Don't krow much about it but it appears to be on paper a .260 in disquise. another good point on the .260 is being able to use good brass as well as the 6.5-06. You can simpley but premium lapua, Norma, or even the Nosler brass in .308 and resize and vwa-la. You are right on the barrel life issue though, and that is consideration. On my big 30's and 7mm's that was not a consideration because of there intended purpose,which is to be shot and broke in, retested and used when hunting and spend time in the cabinet till our time of the year comes around. now it boils to .260, or 6.5-06

    I'm building a 260 because all I had was a short-action. If I had a long-action to donate to the project, I'd go with the 6.5-06.
