Re: Favorite 6.5 Cartridge

what does COAL end up at when the bullet is seated as it is in your pic?

Biggest fail of 2014 so far... http://www.longrangehunting.com/foru...ea-ftf-128972/

My guess on W3P .308 230 Grain Bullet: G1 .740-.755

Re: Favorite 6.5 Cartridge

Yes...COAL...that is my question as the nice long neck on the 6.5-06AI looks able to keep VLD bullet bases out of the powder column...which is what counts NOT just total water / powder volume capacity.
Also, Rich you mention that 6.5x65 RWS brass allows longer necks ...approx how much longer and what total neck length?
Are these rounds (6.5 Sherman & 6.5-06AI)magazine box length restricted with 140 gr Bergers/142Sierras/140AMaxs?
Sounds like you are planning of longer barrel/throat life with this design...ball park #s?

I honestly don't think you could go wrong with any of the 6.5's.
I'm with you there... could easily see myself collecting 6.5's!

Re: Favorite 6.5 Cartridge

CR and Barnesuser, I think the case OAL is the same as the 270 Win which is the parent case, so your cartridge OAL is that plus whatever bullet you use and how deep you seat it.

Right Rich?

Re: Favorite 6.5 Cartridge

My point is I don't want a single shot because the rounds won't feed thru my magazine and I don't want a nice big case that I can't fill because if the reamer throats it out far enough then the short neck contributes to poor runout and throat erosion from the hot gas pattern.
Since the 270 case shoulder is changed and fire forming changes the body taper then that changes the 270's i.e. parent case OAL.

Re: Favorite 6.5 Cartridge

Like many here my favorite would have to be the Swede. I think it is the perfect blend of performance, and barrel life in the 6.5 caliber. Its accuracy is exceptional in standard form and the AI option gets significant velocity increase and even better brass life, and the standard Swede brass life is pretty good.

The standard Swede is a great kids gun for mule deer and smaller game as well. Low recoil, excellent accuracy and ballistic performance all in a small, light weight package if built right.

If I was going to go with something else it would be a big magnum of some kind. Probably Rich's Sherman or even bigger.

Re: Favorite 6.5 Cartridge

Just found the Sherman case Rich sent me... It's 2.527 , about .013 shorter than spec 270... and, about .040 longer than my 25-06 cases.

The CE 130's call for .968 bullet projection in seating which brings the COAL to 3.495. The Mag box in my Vanguard is 3.58 so I am good to go with the CE's. Might just have to do one of these just because it's Rich's Baby

Too bad Rich bought up all the last remaining RWS brass!
