Yup, it does get cold here too. In fact the last couple of days have set records for those dates as far as coldest high temps. We are exceptionally dry here though. Causes worries about the coming growing season. We do have a few big bucks here as you say. I saw two grandaddies, the day after the close of muzzloader season.
I have not had any problems with the old corn shucker (760) in cold, wet or whatever. I have not hunted with the new 7400 yet, so I can't speak to that. Our November season is usually warm but there have been exceptions to that. We also have a late antlerless only season here in January. You can expect a lot of weather in that season.
I really enjoy this forum. I'm one of those that believe you can learn somehting from just about anyone.
As for the sights on that 7400, I have a scope mounted on it, so it's not that big of an issue. I have the type of mount though, so you can also view the iron sights. That has proven useful to me with my old 760. Not having that cost me a huge buck in 1973, and I still remember seeing a lot of hair in the scope at about 20 yards. After that, I bought this mounting system and wanted it also on the new rifle. These sights on the 7400, seem to be mounted too high. I have to cock my head way back on the stock to get them in alignment, then I'm not in a good shooting stance. I would like to replace those sights I think, maybe get something that is mounted lower. Any ideas?
