Re: Handloads & Extreme cold Temps

How extreme are you expecting relative to cold conditions? I have heard of some folks applying primer sealer but I have never done any of that an have never had a problem with reloads in cold, to very cold, conditions in PA hunting or just shooting at the range.

Good night Chesty, wherever you are......

Re: Handloads & Extreme cold Temps

I am a trapshooter and I never heard of this. I have, however, had experinces with Remington primers being "hard" and as such, unresponsive to light firing pin strikes.

Re: Handloads & Extreme cold Temps

How much are we talking? 50fps 100 fps... might have a long shot so that is important and will be hard to mimick here in November. Any suggestions? Thanks Rob

Yes you'll loose some. We have done some testing with my chrono. You have to check your own to be sure. Thats part of long range shooting.

Doesn't matter if its handloads or factory. Clean your bolt well also if its gonna be that cold.

Re: Handloads & Extreme cold Temps

Some powders are temperature and position sensitive...If I recall correcrtly, 99% of them are pistol powders. I believe H335 is as well. If I can locate the list I have, I will list them.

A general rule of thumb is that extruded powders are less sensitive to temp than ball, flake, or even smaller grained extruded. Winter hunters like IMR4064, which cares little about temperature.

I quite often find that loads I developed in hot or humid weather will change POI in cold or dry weather. I usually develop my hunting loads in the winter, and target loads in the summer. Most don't change much, I may lose 100 fps or drop 2" at 100 yards. If you can, resight your rifle just before you hunt(it should be done anyway).

Internet quotes are great, but most are untrue. "Thomas Jefferson"
