better case design for the platform it was designed for.

longer neck
shorter case


Here is a quote from George at GAP...

"Powder Burning does not cause the heat that destroys barrels its the Pressure. The Pressure causes the extreme heat that's necessary to burn and heatcheck the barrel. Kinda like how they make carbon turn to diamond's Pressure.

Anyway the 6.5 Saum case is near perfect because it allows you to throw a 6.5 140gr at 3100 at about 53,000 PSI with H1000. Other cases have too much capacity or not enough. The Saum case was picked not because its magical , because it is the perfect fit. In a perfect world I would take the the RCM case and shorten it a tad and give it a longer neck. That would truly be perfect!!!!


At any rate the 6.5 Saum is working as we thought it would. Here is a thought to those that are still having problems understanding it. Shoot next to a 6mm REM, 243 ETC, any caliber that has a 63,000-68,000 PSI SAMI pressure. as soon as the rifle is fired eject the case into you hands. Those of you that have had a 223 brass land on you or go down your shirt know what will happen, it will burn the crap out of you. The 6.5 Saum with the load im talking about with come out only very warm and you can grasp it tightly with your hand without getting burned. Keeping chamber pressures low not only keeps your barrel from puking early its also easy on your rifle and the components , IE Brass lasts a long time!!

Yes if you hot rod this caliber IE a load of 60.5 grains 4831 SC and the 130VLD at 3400fps you will be pushing 68,000 PSI and toast the barrel in 600-800 rounds.

But the same goes to the guys trying to take the 260 Rem and shoot the 140's at 3000 they are at or near 68,000 PSI and will also toast their barrels early."

Re: 2nd Annual 307 Speed Goat Hunt ... 6.5 SAUM Style

So are you using the 140's or the 130's and 139's? Very interested in knowing the bullet, MV and terminal velocity of the 1268 yd shot as well as a description of the terminal performance. Also a description of terminal performance on any close shots. I've got a 6.5 WSM and a box of the 140 hunters and would like to get as much info as possible.

Thanks and congrats on what looks like a terrific hunt!

Re: 2nd Annual 307 Speed Goat Hunt ... 6.5 SAUM Style

An acquaintance broke his new GAP 6.5 SAUM Precision Extreme Hunter at the range the other day and it performed spectacularly out of the box. Within a few rounds down and tube cleanings in between, they were all going into 1 hole @100. Impressive ballistics on the cartridge. Relatively low recoil with a break. It will be interesting to see if it goes mainstream. I want one.

There's no reason it shouldn't go mainstream. Time will tell I guess. With the amount of testing the 'Hide shooter have posted the writing is on the wall. The bore life is the most impressive part & with low pressure brass life will be awesome (thank god).

From what i'm reading, the 6.5SS & 6.5SAUM are nearly as potent as the 6.5WSM & will actually function thru a short action; something the WSM, IMHO, really doesn't do very well without sacrificing case capacity.
