So my buddy and I were talking about the 300 varminter the other day. (300 WSM, no throat, 110's at 3800fps)
Then we both sort of looked at eachother and said 300-338.
I am hoping someone can do a very rough quickload estimate on potential velocity shooting 110 vmax from a 15 twist barrel.

Yes it's stupid. But I keep picturing ground hogs vaporizing better than dirt squirrels.
And I have lots of 338 Lapua brass with nothing to do.
 
26" barrel

30-338 win mag = 3826 fps

30-338 lapua = 3890fps

300 weatherby = 3912fps

300 mashburn = 3927fps

30/378 weatherby....3962fps

Can't seem to find one to push it over the 4000fps mark....prolly gonna need a 27" barrel on the new 30-378 weatherby!;)

Just screw on a 32" barrel
 
Given that I was able to push a 100 gr bullet to just over 3900 fps in a 257 STW with a 26" barrel using US869, it doesn't make sense that a much larger (bore and case capacity) 30-338 LM can't exceed 4000 fps with a 110 gr bullet.
 
I'm certain that you could break the 4k barrier easily using .22/.30 sabots in a 300-338 wildcat ;)

The first step when using Quickload is to get the case capacity from a fired case from your rifle among a few of the tweaks needed to be done.

Next you adjust the powder burn rate in Quickload until the velocity matches your chronograph.

After doing all this then Quickload will spit out your ball park velocity and chamber pressure.

Bottom line, Quickload defaults to the lowest case capacity and without a chronograph it spits out wild ass computer generated guesses. Meaning I would never ask for Quickload information online because your reloading manuals would give better results.

For best results, measure your bullets (length & weight). Measure h20 case capacity. Change weighting factor from QL defaults to a more realistic #, there's been lots of work done online by guys to make custom WF's for difference cartridges. Then Measure distance to lands, and change start pressure to jam lands (3626psi default for jacketed lead core bullets) + 7200 psi for jamming lands, then subtract 145psi for every .005" you're off the lands. Then adjust Ba (Burn rate) to match chrony or radar. Up to 5%, if more is needed, you can tweak WF, h20, bullet weight, to make things line up. I typically find if I measure everything, the Ba is the only thing that needs to be adjusted. I also set powder temp to 50f rather than the QL default of 70F

Code: 
Cartridge          : .30-338 Lapua
Bullet             : .308, 110, Hornady V-MAX 23010
Useable Case Capaci: 97.220 grain H2O = 6.312 cm³
Cartridge O.A.L. L6: 3.390 inch = 86.11 mm
Barrel Length      : 26.0 inch = 660.4 mm

Predicted Data for Indicated Charges of the Following Powders.

The OP did not give any of this data so any reply to this posting will be a wild ass guess by Quickload.

And my point being it is impossible for any computer software program to give accurate data with all the variations in firearm and reloading component without tweaking and adjusting.

Quickload is a nice program but it must be tweaked and calibrated for each firearm used to get close approximate output data, meaning velocity and chamber pressure.

sure, but you won't find guesstimates for a 30-338 Lapua 110gr Vmax load in any manual
 
What the hell is the point in quickload if I have to chrony it. And adjust it. That defeats 1/2 the purpose IMO.
However for arguments sake.
30" barrel
1:15 twist
114 gr H2O
A throat length of .020"
Bullet jump .020"
Probably need to run a faster powder such as 7828 or H4831 I would bet??
If the 300 varminter can run 4000 fps with 30" barrels and a case capacity of about 80 grs of H2O I was expecting the 338 case to outrun it considerably.

But then again I don't have quickload so maybe I'm out to lunch??

And I cringed every time someone asks a Quickload question not knowing without chronograph the answer is worthless.

Did you ever notice how the reloading data varies between manuals and the firearm and reloading components used.

Each firearm will be different just like the reloading manuals are different and Quickload needs a chronograph.

Meaning without the chronograph bullet velocity from "YOUR" rifle, Quickload can not "guess" what the "correct" chamber pressure is and other accurate data.

And the data in the reloading manuals is from direct pressure reading and a chronograph. So remember about computer generated data.....garbage in, garbage out.

Started using quickload about 8 months ago. Great info here. Thanks a ton
Where can I get more info on W F.

Chronographing your ammo and tuning QL to match your results is what the program is all about. You don't have to use the program, and you don't have to chronograph your rifle. Loading blind is always an option

The above makes sense.

If the 300 varminter can run 4000 fps with 30" barrels and a case capacity of about 80 grs of H2O I was expecting the 338 case to outrun it considerably.

The 30-338 LM should outrun it and will by 300-400 fps with that bullet at the same pressure. The thing is that those playing with the 300 Varminter and getting much above 3800 fps (even with very long barrels) are doing it at well above 63K psi.
 
Just a point here. A local range guy went through all the light .30 cal bullets out of his 300 RUM and found that the 125gr ballistic tip was the only one that reliably made it to the target every time. He was at 4200.

I believe that. However was it a factory gun with a 10 twist barrel.
I think with a 15 twist or similar the lighter bullets should get there in one piece reliably.
