Finished working up my load for my new barrel and my most accurate load came out to be 73gr of RE-22. This is beig fired from a 300 Winmag. I'm getting 3050 fps with no swipes, or any other pressure signs. My last load was no where near this speed. I'm worried that this load is a little to hot, even though I don't have any pressure signs yet.
I might be scared to pull the trigger when the temps hit the 90's too!!!!
So the question is, if any of you guys are running RE-22 and a 190 what are you guys getting for speed, and your guys opinion about this combo if you aren't using this combo.
What is your barrel length?
What chronograph are you using?
Do you trust your scale?
Berger manual says 74.0 grains RE-22 gives 2970 fps in a 26" tube.
That being said, I get 3018 fps using 78.9 gr H1000 in a 24" tube with 190 grain Bergers in my 300WM. Berger says 79.2 gr H1000 in a 26" tube gives 2971 fps.
So, it is possible to get more fps depending on the rifle. But unless you are using a 28" to 30" barrel, you may be too hot.
I have used RE-22 in the past with good velocity and accuracy. In the summer, I started to get pressure signs so I changed to H1000 and have never been sorry.
Using a 26" barrel, and I should have thrown this out earlier too. I'm using RWS brass. I started off trying H1000, RE-22, and H4831sc. All of my charges have been faster than posted speed. It just happen to work out that my most accurate load was my fastest too. But 3050 in winter time makes me a bit nervous. I will rework the H1000, maybe try some 215m too. Don't want to shoot my barrel out in 500 shots.
As for my scale I always calibrate it before I start and check it periotically. My chrono is a Shoot'en Chrony.
