Thread: I've Experienced the Advantage of Hunting with Thermal and Night Vision

The batteries that come with the Sytongs are flat-topped and are about 65 mm tall.... or maybe a tad under. Some 18650 batteries are quite a bit longer and, as you say, they have a button top. Although the battery holder has a spring, I don't like to force longer batteries into the holder. So my 'special' battery is a short one with a flat top.

I'm pleased I sighted the .223 for 100 metres. No matter what range a rifle is sighted for, it can't change the trajectory of the cartridge anyway. So it is a matter of becoming familiar with the trajectory and being sensible. I doubt that I will ever bother about getting a scope that is easy to dial for various ranges. I've only just graduated from iron sights. And I've pretty much spent the 'retirement gift' I gave myself which was a permission slip to buy a few hunting accessories.
