Temp ????

How does the temp outside affect the accuracy of your muzzleloader? I sighted mine in when it was still hot out. Now that its getting cooler out should I resight?

... or you could wait another 5-6 weeks - then re-check/tweak it an inch or three.

You want to know where that bullet is going in the same, approximate climate that you're hunting in. There's no way I can tell you how much your target holes will change from 80 degrees to 35 degrees (hypothetical). Way-too-many variables to consider for that. The best remedy is to get out there & tweak it as need-be.

Absolutely!! Where we live the temperature, as you know, can be very drastic and change in front of your eyes. I try to do load development in the spring before the high heat and humidity set in but invariably life never works that way, soI plan on trips to the range in the fall to check. I need/want to shoot my loads at 10-0 and below freezing, as it replicates our hunting temps. Pretty
cheap insurance IMO.

I believe higher temps and higher altitudes give an advantage in flatter shooting ballistics, so you will want to make sure the difference isn't big enough to worry about when it gets colder.

How true that is! Just ask a major league baseball hitter how far the ball willtravel in April andOctober versus those hit in late July.

Hot weather helps bullet speeds, but at the same time, that time of the year produces high humidity in many parts of our country. That affects the powder then. There is a never-ending battle to get your ML bullet to fly the same year-round...... sometimes even day-to-day.
