Great reading. RR and Dewey are spot on. 3150 with a 150 is pretty quick. Ackley's change the dynamic of brass flow and traditional pressure signs. That's why most see larger gains than normal when going from a standard to an Ackley. The case walls grip the chamber tighter and more secure, not allowing the case to move back and print an ejector mark or flatten the primers as much as a slightly tapered case.
It looks like your top end would be in the 3050 range for your set up. I wouldn't quibble over 25FPS either way, as a chrono could give you that much error depending on its maker or the atmospherics.
The fella's are providing excellent information and will get you tuned in Muzz. I have had QL for years and haven't messed with the burn rate of powder. I usually just match my observed speeds with PSI in QL to get my ceiling. I by no means baby my stuff, but as RR mentioned, brass is expensive so I try to keep the primers tight. It's all a trade off.
Great information and discussion. Hard to get straight scoop like this in most places.
Muzz, as for getting H20 capacity. I cheat. Mike does it the right way, I do it Scotty's way, I turn the faucet on low, fill the case till it over flows then wipe it down so its dry on the outside. I get close enough for my work. It's a measurement of the entire system, I don't look at it as the end of the road. I weigh three to five cases if I have them. If not, I'll do one. It's a starting point to get me in the ballpark. Shooting the gun still has to occur to get baselines.

Muzz,
None of this is intended as a criticism at all, by the way.
FWIW, your load at 3234 fps was on the fourth node which probably explains the accuracy you got (which was outstanding)
Node 4 hi and low times should be .10796 to .11236. Your load is right against the .108 or so.

starting to think of tradin it off for a 7 mag
Not butt hurt at all by anyone. I appreciate the help and knowledge. The only thing that bothered me was no one came out and said
HEY DUMBASS YOU LOADING IT TO HOT!!!
I get that I might have taken it wrong and no one wants to be thought of as an ass, That I respect. But damn that scares me to think I was loading it that hot and something bad could have happened. But oh well its all good. Like I said im not butt hurt and glad you fellers are taking the time to help me.

There's nothing the 7 mag can do that the Ackley can't do just as well...
Except burn more powder for a negligible increase in velocity.
How far do you plan on shooting? If it not over 800 yards there is no reason whatsoever to move up to the Rem Mag... Not knocking the Rem Mag, its a fine round.... But the only time its any better than the Ackley is with 180+ grain bullets at long range (over 800 yards)

If I were gonna move up... I'd go to the 7mm STW or 28 Nosler, and get enough boost that I'd notice it.... But from what you've posted on this forum so far.... I really don't think you need to move up to anything, unless you just want to.

Dewey,
The numbers look good to me.

Scotty,
Dude.... You gotta tweak that burn rate man... Its easy as pie, no permanent changes are made, as soon as you unclick the powder edit button and switch powders it reverts back to the default values...
You can permanently edit the powders... But I assure you, you won't do it by accident.... It takes some special steps that one couldn't make by accident.
None of the burn rates in QuickLoad are accurate across the board... They all vary based on case capacity and other factors.

No guarantees the Rem Mag won't be just as bad... Or worse... It is commonly known to be a finicky round.
The most you'd have to spend, I think, is maybe for a different powder... Maybe... Don't give up on 26 yet, though.... We're not done.
And if it comes to that...I recommend IMR 7828 SSC.... It has quicker barrel times, with only a slight loss in velocity.... Might reach node 4 with it, or like me... use Norma MRP (sort of expensive, but I like it)

I guess the question is... Do you want to do this with the Ackley or something else?
If it's something else... Now is the time to decide.

I'll help you all I can.... I make no promises on the end result.... But I'll work the data as if it were mine.... You just have to provide that data to me.

If you really are gonna use this rifle at 1,300 yards on deer... You do need to trade up.... The Ackley, regardless of bullet weight, runs out of steam at 1,000 yards (falls below 1,000 ft. lbs.)... The Rem mag isn't noticeably better.
At 1,000 with the Ackley you'd also be better off using the 168 grain bullets... Node 5 will be easy to hit with the powder you have.
If I sound like I'm changing course.... It's because I am a little.... Didn't realize you were wanting to hunt that far.... The 150 ABLR's will do it.... The 168's (either Nosler or Berger) will do it better.
