DLFant- what barrel length are you shooting to get 3005?
Greyfox 3005 seems a bit high for all that I have read. Now when I say 22 inch I am not counting the break that is 2 more. I use the shooter app I have it on my phone. The trick I use a good friend showed me was to shoot a couple groups at known distance then adjust the velocity data in your ballistic program to match. Rather than the other way around said:Thanks DL,
My same load setting your altitude and temp shows we are identical at 500 yards, and my load at 2941FPS at 725 yards requires +1MOA more than your rifle,(3clicks, I also use a Huskemaw) You are getting good velocity for that load approximate 50-60FPS more using my velocity calibration in Shooter! My 58gr Retumbo load gives the same drops as yours.
Next time I get to use my buddies chrono I'll throw some more of the bergers through it. Last time I got an average of 3150 but it is possible maybe something was wrong. Curious to see myself. Edit* I wonder if perhaps the chrono was too close and giving a false reading,BUT we shot 5 guns through it with out moving the chrono or the gun rest and the reading for the othe 4 were right and matched out drop data. Including his 300 wmCould be a fast barrel or small bearing surface lot of bullets. I have had 3 now and none have come anywhere close to those speeds. It bums me out really. Would love to be able to run a shorter barrel. In order to achieve safe velocities over 3000 I went with a long barrel.
On a side note, have any of you tried the 140 amax in your Savage?

I hear what you are saying but that sort of velocity (3150) is so far above and beyond anything ever published it is just amazing, especially with a 24" barrel. I do realize that every once in a while a barrel will be fast and accurate, which is the mother load of what we all want.
Running a 28.5" schneider and shooting just under a pressure node I am able to get 3025. Shooting the exact same load in a 24" I get 2900 to 2920. This is with Retumbo which is definitley producing faster speeds than 4831 when I tested them back to back. I run 2900 in Shooter for that rifle and 3025 for the other and I am good to go out to 1400. At the Vortex challenge I tried the 1725 target and both rifles fell short. Probably because the efficiency is just not there with non-stepped BC.
