-Higher BC than 308cal...308Win is great but if you handload the 7-08 is greater...if you so popularly "loose" your ammo if someone has ammo the odds are better that they have 7-08 over 260.
-Cheap to shoot....equal or lesser to the cost of 308Win
-Good brass available with minimal work to run 308Win Lapua brass for 10+ reloads
- Not even close to a barrel burner---same as 308 Win though...probably less life than 308 Win
-Can run it in an extremly short barrel--older pumps would run 16-18"
- Broad range of powder usable in it---for 175gr SMK Sierra liste everything from Varget to IMR4350...Varget for the 223 and IMR4350 for the other mag rounds....less selection of powder needed when buying bulk
-A 30 MOA base is plenty for a 1000+ shootout...probably go 20MOA if you wanted to push it near the bottom of turret
-Minimal recoil----same or less as 308Win probably more than 260 though
-100gr up to 175gr is common bullet weights....180Berger if you want to but from what I have gathered if you want to run the 180Berger you would need to run a L/A and would be way better served with a 280AI
I do not own either but the 7-08 will be my next rifle I have built up...put your imagining glasses on for a minuite.
Buy a 5R barreled action or full rifle and sell off the barrel or keep and build slowly....there is a 5R barreled action here for $650 that I really want to commit to but.....basicly get a SS S/A .473 action and put a 1-9" twist Rock on it in Rem Varmint contour....cut to 18" and mount in an A1-3....pretty frigging light riflr even built with a Sniper Fill MCM.
Other option and the more realistic option for me is buy a SPS Varminter off of GB for $500 and sell the stock and bottom metal....get $70 for them off the Hide....use a machined follower from my bone yard and use the SS ADL trigger guard and the Walnut ADL stock...easy enough to open the barrel channel and start out with the 26" barrel and hacksaw it off 2" at a time....with a mild load and find an average velocity drop for that barrel....usng that velocity info for my custom made barrel length...pull the trigger and base off and have a local machinet buddy chuck up the barreled action and give me a good crown at 18".
When that factory barrel is wasted...7-8 thousand rounds later spin on a custom maker barrel...sooner if funds allow.
This is just what I go to sleep thinking about but maybe the 260 is a better round for you Dafar????
The RSO should chime in here sooner than later with the pros for the 260!!! </div></div>
Joe,
You present excellent arguements. However, my advice to Dafar is to not go with the 7mm-08. For a short action, non-magnum 7mm, my advice is to build a rifle chambered in 284 Winchester.
284 Winchester is an original "wanna-be" short action magnum. It uses the standard .473 bolt face like the 7mm-08, but then widens out to .501 inches. The 7mm-08 holds 55.0 grains of water. The .284 holds 66.0 grains of water. Both cartridges were designed for shooting 7mm bullets in a short action.
If I was going to build a <span style="font-weight: bold">NON-magnum</span> 7mm in a short action, I would go with the .284 Winchester.
Here's some numbers for you.
