I have a new Rem model 7 with a 20" barrel and am loadind 150 grn Rem bullets. With RL 19 I am getting 2500 fps safely. That is with a max load. I have not tried any other powders yet, but wanted to see if I was in the ball park. To be honest I expected more as winchester factory ammo was doing 2650 with 140 bullets.

Those velocities are right in the ball park for each weight bullet with a max load. The 10 gr difference in bullet weight means more then you think. I would not try to get the 150 going as fast as the 140.

I have a 20 inch barrell Winchester classic compact. I get about 2750 with remington green box 140 grain, and 2650 with Federal 140 grain partition. I did get 2400 with a notch less than max with H4350 and 175 grain hornaday spire points.

It looks as if you might be a bit short on performance as I'd expect about 2,700 or so even with a 20" barrel. I'd try Varget, IMR or H-4350, IMR-4007 SSC, or even H-414.

What warning (pressure) sign did you incurr that lead you to believe you was at the max on pressure?

I picked up some H414 today and will work up some load with that, if that doesn't do it I may try either H4350 or Varget. I reached the max listed loads in all of my manuals, 49 grns being the highest listed load I found. I meassured case expansion and compared it to factory loads and everything seemed fine so I up the load one grn to 50 grns. Velocity went up to 2550, but the primers looked a little flat, and the case expansion went beyond what I was comfortable with, so I settled on 49 grns as max with my gun. Bolt lift and extraction were fine however.

I have a Rem 700 20" barrel in 7mm08 and get 2840 fps with 140 TSXs and 44.5 gr of Varget.

Varget is a great powder. RL19 (Right there with 4831.) is kind of slow for the case. You will be able to get what you want by changing powder.
I was only looking at the RL19 info for you to show you were already at the top speed for it.

My 7mm-08 is a 20" Rem stainless. I get 2820fps with 139gr IBs using a max load of IMR4895. I tried RL19, and IMR4350 but just didn't get the velocities I wanted. I did get into the 2800s with 4895 and RL15. Keep trying combo, you'll find a good one.

I tried the H414 tonight. 46.5 grns gave me 2743, at least for one shot. After It was getting to dark to get any more readings. I will shoot a few more tomorrow with better light and see if I get the same readings. If that is the case I can live with those figures. If I can get the kind of accuracy I want I will be good to go, if not I will try the Varget, everyone speaks so highly of it I may try it anyway.

Varget is a surprising powder. I have a 10" MOA, 7BR pistol that I wanted to use the Hornady 120 gr SSP bullet out of. I could not do more then spray the 50 yd target. This gun will shoot into 3/8" at 100 yd's with heavy bullets.
I had some Varget and E mailed Hodgden for a load. They said it wouldn't work and they had no info.
I went to work and found a super accurate load with the bullet that just doesn't match the gun. It burns clean and the velocity is also up pretty high, just about matches all the other powders. I was very happy and it will be my deer load with the gun.

Well the H414 averaged 3 shots at 2710 fps using 46.6 grns. and 2680 with 46 grns. I will check the loads for accuracy this weekend and see what happens. I am still going to try the varget out though. Thanks everyone for you help and suggestions.

that's not REALLY a short barrel...

a REALLY short barrel is the savage striker... in 708, no brake.. 14", I had and loved it.. but it required a very stready rest... calling it a pistol is charitable.

the same vraet loads with 139s that I was getting 2850 with from a 22" rifle would go about 2600FPS
