Hello,
I have had great luck with MRP as of late. Had my 300 re-barreled 2 mos. ago, found a great load and have been shooting almost every other day since. It has been hot in Nevada so the other day I wanted to beat the wind and heat/mirage so I headed out about 6:30 am. It was 58 degrees that morning, at least 30 degrees cooler than when I am able to get to the range. I had almost 60 fps less that morning than I usually have. 60!!!! I could not figure why I was off so bad on my long shot (1784 yds) So I hooked up my Magnetospeed and found out my Velocity was way off. My SD was still low but I am at a loss for the velocity difference.
I know there has been many articles on powder and temp. sensitivity but has anyone had an issue like this with MRP in particular?
Thank you,
Eternal
