N135 in cold weather

[Dave T]

Ok all you 6BR folks, I want use N135 in my 6BR Sunday in a club match, it is going to be in the 50's Sunday and I've had good success with N135 in hot weather and I'm out of time to do any testing in colder weather. Any experience with temperature changes with N135 in a 6BR would be greatly appreciated. I will be using the new Berger Column bullets. I guess what I'm asking is it your experience to bump up a little in powder charge from 90 degree weather to 50 degree weather.
Thanks,
Dave T

I shoot vv135 out of my BRDX with 80gr Fowler's. It's been good for me in the cold wether. I shot it last Saturday in wheather in the mid 50's and had to give it .2tens more to get it back in tune as usual. hope that helps

I add .2gn for every 59°F temperature drop from my original load.

I hope you never have to go down another .2. That'd be too cold for me.

the coldest Ive gone shooting BR is -3°F, hottest is only 65°F average is about 41°F

Does anyone have a way to keep their ammo warm somehow when it gets below a certain temperature outside?

I would think a hot water bottle in a small cooler would do the job.

My question should have been worded differently. Do any of you actually go to the trouble of keeping your ammo warm in cold weather? If so, how do you do it?
I got caught leaving some 222R ammo loaded with N135 in the truck overnight at 26 deg.F and it shot horribly the next day. Having preloaded for the match, it was not possible to adjust the powder charge up. Even if it was an option, I don't think that increasing the charge would have helped. Please excuse if this is off topic.

Get some disposable hand warmer at Wally World and stick 'em in a cooler with the loaded ammo.
