First I'm debating about load development in the summer months compared to winter shooting months. I mostly test loads in the heated summer days. Where I hunt , Snow is on the ground 80% of the time during rifle season. I am up in the air about this? Do other guys take the time out of the winter rifle season to sight in loads? This gun will be a 300 plus yard gun only. nothing really closer then 300. Anyway im dumbfounded with this.
The guys that do shoot l.r. and reload are you using a chrono to test loads? If so at what distance are you testing at? I have read articles about chronos and im undecided?
I have a round i like as of right now. It was tested in the summer. 100-300 yard test.
I would love to test loads at 100 and 500 yards in the winter and then get leupold caliber specific knobs.
Depending on what brand of powder you are using you need to check velocity swings from summer
Some powders are temperature sensitive and some are not. so testing your load will tell you if you
have a problem with this.
During the summer I load down from max and during the winter I can up the powder charge
if I have to on some powders.WARNING!!! These loads should not be used during the summer
and should be marked so.
I chronograph every thing I load at 16' and measure drop out to the distance to be used because
with temp changes comes other factors that can effect bulled flight.
The chronograph is a wonderful tool for long range shooters but it will not tell you what your
bullet is doing at different distances.
Take/make the time to sight in during the winter. Most serious long range shooters even check
zeros when changing altitude.
