Re: 6.5 saum

For you guys that wont read through the Snipershide post to answer all your questions. New GAP Extreme Hunter in 6.5 SAUM

Here is what George from GA Precision has to say from page 5 from the thread.

Originally Posted by 7mmRM I'm very skeptical. I did the hot rod 6.5 some time ago. (264WM) 600 rnds it was done. That said, I am quite intrigued with this 6.5 SAUM and seeing for myself if it lives up to claims posted here. Anyone care to give me neck and FB dimensions, I'll get a reamer ordered today....

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.


Just some Afternoon Info.

Just sayin

It has the same H20 capacity as a 6.5x284.
Over the decades many many have competed with a 6.5x284, and it's done well.
Accurate Barrel life: 1200rnds
Unless his barrels are Melonite treated, I doubt he's bettering this.

Even the mighty mouse 6.5x47L will not produce beyond ~2000 rounds of accurate barrel life.
Just watch the numbers come in..
take the time to read the thread unless you are saying the man is a liar it is spelled out pretty clearly that the saum will break the 26 cal bbl life record with ease ........just sayin

Re: 6.5 saum

I have been following this thread and the one on snipers hide. Both are very interesting to say the least. A friend at work has a rifle built by GAP (.308) and as of last week sent his .308 back to GAP to have it redone/chambered in the 6.5 SAUM. I have no dealings with GAP, but many others have. George who I believe is the owner operates a reputable business and therefore I would "assume" is a reputable person. My question is, what does a person like that have to gain by making false claims of a round count through a rifle barrel. What he is saying makes sense about the pressure! The speed and accuracy are there with out all the pressure.

My 6.5-284 is recently completed (waiting to pick it up) but if I would have know about the 6.5 SAUM earlier on, I would have tried one out. The only thing I do not like about the 6.5 SAUM would the case preparation. Maybe down the road when my 6.5 goes south, they may be producing brass for the SAUM.

Re: 6.5 saum

Any 6.5 that can throw a 140 gr bullet at 3100 with 53,000 of pressure would have a looooooong barrel. I just yesterday shot 62.5 gr of H-1000 behind 140 MKs (HBN coated) and got 2914 fps (28 inch barrel). This was not maximum but I will bet my pressure was above 53000. The case was the .270 WSM necked down to 6.5.

I just don't believe 3100 fps.

Re: 6.5 saum

First off, I'm not calling anyone a liar. That said, there are some things that have been said that I am having a hard time with.

That would truly be perfect!!!!
1 - I'm a little skeptical that 53,000 psi of H1000 in a 6.5 SAUM is pushing a 140 @ 3100 fps. Is there any Quickload data on that?

2 - I don't buy "the perfect fit" business. If you go to a larger case, like let's ay the 6.5 WSM, You will on average get higher velocities with more powder at equal pressure. Example. I own both a 300 WSM and a 300 RUM. When I load those cartridges to equal pressures the RUM will produce at least 300 fps more velocity than the WSM. If i wanted to extend barrel life in the 300 RUM I could reduce charge and pressure to much lower than the WSM to achieve the same velocity. The charge itself would still be greater, but the pressure would be much lower. Point being, there is nothing "magical" about the "fit" of the SAUM case.

Now reducing the load and pressure will increase barrel life, and it might even do it exponentially when you get down to certain levels. I really don't know how all that plays out. But I do know that bigger case = more velocity with equal pressure.

Kurt,

Are you calling 6,5 WSM a liar? Are you saying he should just keep quiet and not share his info? Hear no evil, see no evil, speak no evil?
