Last time I had shot long range was during the summer. I have all of my data recorded.
Rifle 300 RUM
Primer Fed 215M
210 Berger .
MV 2900 FPS
Now for my questions
1. I bought a new pound of Retumbo powder so what should I expect when I run the same MV into my ballistics soft ware, this being a different Lot ?
2. What about the Temp. change ? It will be colder when I try and shoot tomorrow than when I was shooting back in the summer ?
I will have all of my answers tomorrow but I just wnated to hear your experience .
Thanks for taking the time to read ...........,
