You ever hear the phrase "the whole 9yds"? It's because A-10s have 9yards of ammo feeding each gun

The search function isn't very good as I just tried using it. Instead I had to use google to find it
200 grain 6.5mm bullets.
This is a little reminiscing mixed with high expectations. I was going thru P. O. Ackleys' "Handbook for Shooters & Reloaders, Vol. 1, the other day. I've always had a certain affinity for the 6.5 so to speak. Upon reading I had forgotten about the mention of 200 grain 6.5 bullets. They were...
still not correct (facepalm)
Got it
200 grain 6.5 revisited (Attention Elkaholic, and Hammer)
New thread began to avoid hijacking the other. OK Rich I've apparently painted myself into a corner. Apparently EOL and Berger are moving forward with a 155 grain 6.5 bullet. I have 2 actions to play with a #1, and a magnum Montana 1999. Which case do we play with? Open to one you haven't...
Wow if they have 2 guns that's a little over 8 seconds of ammo!

Not the biggest or fastest but I'm surprised Nosler and weatherby haven't put out out light fast monos for their new creations. The 6.5-300 wby should be able to push a 100 ttsx to 4K, did the math, around 3500 foot pounds of energy so not at all an out to lunch expectation. I
See little stopping the 27 Nosler from doing the same thing with a 110 ttsx. Perhaps the twist rates set up for heavies wouldn't result
In good accuracy.

That's insane. And I have to admit I'm having trouble understanding how you do this safely. Not at all trying to be contentious or arguing, not saying I don't believe you, just saying I don't understand how this works. That's 6400 foot pounds of muzzle energy (also I want one now). The data for the .338 lapua and .338-378 wby doesn't suggest they come anywhere close to that kind of horsepower but they're similar capacity. I know full well the only thing requiring pressures stay at 65k is brass elasticity, not action strength. What's your brass life like? Is this an ultra pressure load? Does the 34 inch pipe really add this much extra to it? I'm legit curious and want more info about this rig.

My 300 Raptor makes 6200ft lbs with 245's. In theory it could do 175-180's at 4k with a mid .5 B.C would be quite potent
The combination of a very long barrel and RL17 will produce amazing velocities. RL17 produces velocities in my short barreled 30-06 that can be hard for some to believe.
I know of a 300RUM with 124 Hammers running them @ 4100 and some change
Don't worry about it I like when I am questioned about my loads and fps numbers, I like answering them because I have nothing to hide and don't fudge the numbers since there is no need to. And to add to that these numbers can be repeated any time, any time, any place, and in any conditions. Not some nuclear lab under Ideal conditions, I have got even higher numbers than that I have posted but do not feel comfortable reproducing the load repeating them or posting the numbers.
As far as the brass RUM brass does not last no matter how you load it, so I say screw it and take no prisoners. And as far as pressures go I am sure I am above the 65000 mark but that does not mean that at 66000 evrything goes awry, that is not how it works there is some saftey built in. I could be at 70000psi or even 75000 for all I know, flat primers are a given so I don't go by that heavy bolt lift however is where I draw the line and back off, there are other signs but that is my main one and has never let me down. You can get away with higher pressures with light bullets since by the time the pressure Peaks the light bullet has already started to move forward and is dissapating the pressure, so the peak in pressure is there far less longer than it's heavier counter part IE:300gr And as far as the numbers there is no one thing it is a combination of Those TTSXs with there short bearing surface, the RL17, the long barrel, it's slow twist rate, NON MAG Primers also help in keeping the pressure under control, I also jump the lands 100 to 125 thou I suspect that chamber has a lot of free bore to which all helps with dissapating the pressure. all these things together make up this ungodly round. I have a shooting buddy who has a 700P in 338 Lapua that I load 100gr of RL17 and he gets 4000fps with those 160s He cracks me up he has those 50 round ammo boxes and when he goes to the range he has 40 rounds loaded with 300s and 10 with the 160s in the same box.LOL

Huh, We must be Kin
I would like to add that I have no scientific proof of my findings, I don't have a balisitics lab or any pressure measuring equipment. All I have is years of loading and testing and observation, and still being here to talk about it and share my findings with fellow shooters, so take it for what it's worth.

25 years ago=250 grain Barns @ easy 4550 in the 375-50BMG aka MachV. Had more room to go up but accuracy was terrible! The 243,6-284 and 308 Baer would get over 4k with light bullet with mixed results
