140 Partition, WLRM, 2.805", Rem brass. 2870 fps at the muzzle.

Thanks P, I'll see what 47.0 does and maybe go up a skoosh....
Makes a big difference what brass your using. Remington brass will take 47.5 gr. Of Big Game under the 140 gr. Partition in my 7mm-08s no problem and like Pharmseller, I get a little over 2800 fps. However, I’ve got a couple hundred Lapua brass that I back the load down to 46.5 gr. and get the same velocity. Lapua brass is a little thicker than Remington’s so builds pressure with less powder.
If we live long enough, we all have regrets. But the ones that nag at us the most are the ones in which we know we had a choice.
In my 7-08 41.6 of RL15 and 140 Nosler Bal. Tips work wonders.
RL15 is a great powder in the 7mm-08 and is all I used to use. I just like that Big Game gives a little more velocity, is clean burning, and is temperature change resistant. Plus, it is more accurate with the 120 gr. Ballistic Tips (in my rifles) which is the bullet I shoot the most.

[quote=243Win but undoubtdly your rifle can handle a load over 64,000 psi.
most modern bolt action can handle 2 times that pressure, Remington test there actions at 175psi with no failure
Holy crap!?
Well let's put it in an easier way if Remington actions could only handle 65000 PSI, Remington would be sued to death an out-of-business that's why they're pressure test them so high for liability. On a another note I friend and I tried to blow up a rusty Remington action once for a hunter safety course loaded a 30-06 full of red dot. Tied it to a tire after the dust cleared and a tire quit spinning we examine the action and nothing was done to the action other than the bolt expanded out into the counterbore that you could not open the action, had to remove the barrel to get it apart. The brass was also expanded or welded to the inside of the chamber, primer pocket double its size.
Back in the late 90s RL-22 had a problem and they did a recall on that powder as it wasn't mixed properly and it had a high pressure spike. I had about 15 lb of this powder and I called and they told me that the samples that they tested had a spike of about 87000 to 95000 PSI, I used this powder, had 15 pounds of it, till after the 3rd round of all the primer pockets enlarged. That said action is still running today and is good shape, it's a blueprinted 700 action and it shows no sign of stretching or bulging of the action
I recently put together a Howa Mountain rifle with the lightweight barrel and bansner stock. Also had it bedded and factory trigger tuned and set to 2.5 bls.
I tried several different loads using 120 NBT, 140 NAB, and 150 BTs with Varget and RL17. Everything was around 1-1.5", although these were the first rounds down the barrel.
Then I found some Big Game and decided to try Pharmseller's load. 140g NAB, 47.5g Big Game, Win LR Mag primer, at 2.800" and the first load shot like this. 2,820 FPS in a 20" barrel. No more load development needed.

And a single shot at 225 yards will drop any bull.
Note the entrance wound.

Obey lawful commands. Video interactions. Hold bad cops accountable. Problem solved.

My bbl is 25.5" long and my load is 45.5gr of RL17 .. I have loaded my nosler brass 5 times now with this load and that brass is as tight as the first time I loaded it. I guess Berger is releasing dangerous load data then .. They got 2830 fps with a 24" and 45.9 gr of RL17......
Berger doesn't test loads with pressure barrels, it publishes QuickLoad predictions.
You're 70 fps over their max guess with 1.5" more barrel.
Not country I care to be in... but undoubtdly your rifle can handle a load over 64,000 psi.
John Barsness has a 7-08 load posted in his The Big Book of Gun Gack of 45.5 Re17 behind Nosler 150 BTs at 2827 fps with a 22" barrel. 243Win's load with the 25.5" barrel seems reasonable. I've been shooting the 45.5 load for awhile albeit an OAL of 2.86" and get just over 2800 fps in a 24" barrel.
