260 rem

...or 6.5WSSM which can easily reach 2950 or more.

Agreed but finding brass can be frustrating.

I have shot F Open for a few years off and on since 2002. My rifle is a 2001 Savage 10FP restocked with a McMillan A3, uses a L-W Stainless 28" 1:8" Savage Varmint Contour pre-fit, and a Sharpshooter recoil lug and trigger. Ken Farrel 20MOA base, Burris Signature "Zee" Medium rings, and a Mueller 8-32x44 target scope.

Load is Win/HDY 7-08 brass necked down to .260 spec (just run it through the .260 F/L resizer die), CCI BR-2, 142SMK, and 43.8gr of H-4350. I had a pair of the barrels, made in the same run, and the better powder charge differed by .1gr at 43.8-43.9gr H4350. Velocity varied some with weather, and drop with altitude, but hovered around 2850FPS, and 28-30MIN above 100yd zero at 1000ft ASL. I have shot this load rather successfully out to 1KM (1123 yd nominally) at Whittington (alt about 6000ft ASL or a bit). Density altitude means a new range card for each range, and the higher the altitude, the better the rifle shoots (Less time of flight).

There are no 'identical' barrels. ...Or maybe the headspace was a smidgen out of sync...

Next month I move to So. AZ, and 4800ft ASL. Weee-Hooo! But wait, would I then be JarheadAZ?

Be warned in advance that you will shoot wonderfully, only to take second to the 6.5-284. But seriously, the match will go to the shooter with the best wind skills. The barrels are identical, and so are the bullets, the only difference is the chambering. I chose the chambering with the better barrel life. And watch out, the 6.5x47 is gaining on us...

I shot this on 5/1/16 at 1000 with a .260. Load is 44.5 IMR 4350 123 Scenars. Yes, I was lucky to shoot that group (at least for me!). But, I shoot a .260 to 1000 regularly with 139's and 142 MK's. I do not stand on my brass, generally 42 - 42.5 H4350.

Hi Kochie,hi Jon,hi all

Kochie since you ask about it,I really can't see why you folks in the States seem to stick to american calibers,and quite strictly so...Of course I understand that it makes it easier in terms of availibily,tools,what not,but why don't you sometimes drop an eye on what Europ has to offer? 6.5x57 is a classic round over there,the case is the 7x57 necked down to 264.I believe that 7x57 Mauser,the parent case,or the 257 Roberts(some authorised wilcat)are pretty easy to come by in the old US of A;it countains a good deal of powder as opposed to the 308 case;if you want a reamer,in case you decide to go wildcat,JGS has one(I designed and ordered it)that goes by the name of 6.5x57 imp 30° CB,I reckon you'd be much more comfortable with a .295" neck rather than the .292" I asked,but it's there...I will give you details about how it goes pretty soon,stay tuned gentlemen.Just my 2 cent.Take care and good shooting.

You'd be surprised how not easy it is to get some brass here

What part of Az are you moving to? 4800 ft would almost have to be around Prescott. Some good ranges around and a lot of open country to shoot.

Pearce/Sunsites. SE of Tucson, 191 S of I-10 between Wilcox and Benson. Looking at Douglas range for starters (4006ft ASL). Am JarheadAZ on AZGO site.

Scheduled departure from NY May 24. Lotta work to do between now and then.

Sierra vista has a range. I'm not sure of any others. I just moved form willcox. You can find open spots to shoot though. It's not back east. There is a ton of open land to shoot

 

[JarheadAZ]

Some minor issues with getting Internet access, I am now in AZ; been so since Saturday of Memorial day W/E.

Am in touch with a Range master at Douglas Range, but a series of move-in chores and the Summer heat have kept me very close to home base. I expect to be fully engaged by early Autumn. Priorities intervene for now.

I have been interested about Sierra Vista range (and LGS options) and intend to get the location nailed down presently.

Basically the biggest difference is barrel life. You'll give up 150+/- fps with the 260 but you'll gain time on a barrel. I get around 2850+/- with 140s. Same bullets I go to about 3000 with my 6.5-284. Both are equally accurate and recoil isn't much different. My 260 has around 2200 RDS thru it and it's going strong. Never will I get that from my 6.5-284. Purely a coin flip in my opinion. Both excellent 1000 yard guns.

 

[chromatica]

I chose .260 because it has the largest case volume of any of the 6.5 short action cartridges. I'm shooting SMK 123s using Lapua 260 brass and IMR-4064. (And I scored a used Co-Ax press for $25 to make sure I am getting the most concentric ammo.)
