Hi,...i'm new comer here!
I interested in this topic since "night hunt" is the most preferable method and legal here in my country. I 90% night hunt. :-) and wildboar is the game.
Let me share on this thread...
1. I think you can use both strong spotlight or the red lens. I myself more like the first one. The light possibly to make their eyes "blind" in a moment while we can easily see them! In a not foggy night and open terrain, i can shoot them at around 250meter range with 1million CP spotlight, even more. I would say i'm specialist on this...
Sometimes i use a Bushnell rangefinder, but you can also judge the range "more easy" if you're familiar with the field and have many experiences in "range's judging".
It is common here night hunting in "a team" (3-5persons) using a 4wheeler/jeep that has a "special construction" on top of the roof.
I "4wheelers hunting" in open terrain and if it's not a fullmoon. (darker night is more preferable for this method). A skilled driver and one or two skilled "spotlighers" are needed. (the spotlighter also as a "guide"). You know, not rare we found others animal when "searching" by the spotlights. In longer range, say more than 200meter at night...it is very difficult for "unskilled eyes" to "know what (game) is that?". Not rare we can only seen its eye(s)...even in brushy area. That's why i say "skilled".
Perhaps it was not your type of hunting method...?
2. "Stalking hunt" also another type. It can be a fullmoon condition or in a dark night. (also in the late afternoon). Here almost of us can walk in a dark night without any light, even we didn't know or familiar with the field. In a fullmoon night we can even find game's track (on the soil).
We then use the battery spotlight we carried if we feel there is/are wildboars overthere and shoot...! Sometimes i only use my scope, depends on the condition and if i'm sure "what is that".
European scopes like Zeiss, Scmid&Bender, or Swarovsky are favourite for hunting scopes here. (Leupold is favourite for target shooting because its second focal plane). A variable 3-12X magnification in heavy duplex reticle is fine. My Zeiss Diavari has adjustable luminated reticle, it was helpful in a quick aim and dark condition. (don't use fine duplex). I also make a lasersight system under my hunting's barrel (in front of the forearm) for a quick shot. The on/off button is right on the grip, easily to touch with my right thumb while aiming. But some wildboars was frightened with the laser's light!. I ussualy head shot, i could see the game's eyes become very "brightfully red" with my laser.
I also have a night vision device (russian made, gen 1+) that sometimes i used it when stalking or still nighthunting. Sometimes i hold the device with my left hand while my right hand hold the rifle and aiming and shot the game. The dot lasersight was helpful.
I guess a NV goggle will perform better.
3. It is similar thing when "Still hunt". It could be in a "treestand" or on the ground, depends on the field.
With a "skilled" ear, you can easily "detect" the game came from, especially if the wind "help"...
I have a "Bionic Ear" device i've sold last year (a big dish, speaker and a headphone), because it was too bulky and not efficient!. Now i only use what nature gaves me!
4. "Using Dogs", but i've never tried it. But i think that's a good one...
Just do not use a shotgun, even in a full choke...if you didn't want your dogs hurt or dead!
Okay, that's my "story"...
BTW, we're fans of bolt action here. 30.06, 8mm mauser and .308 were amongs the popular here. I shot .22lr, 223, 7x57, 7,62x39, .308, 30.06, 8x57. A little of 12 GA and .416rigby (but it was). I also shot "benchrest" and target paper/silhoutte, but due to "calibers selection" here, i'm a fan of 308.
