I see post referring to truck guns. What is the definition or criteria for a "truck gun"?
Just curious.
it means a lot of things to a lot of people
at it's most simple it is a gun you keep in your truck.
typically utilitarian in purpose
my truck or rather Van gun was a bolt action Mossberg with a C-lect choke
I gave 75 dollars for it used , it shot very nice patterns , it was in good shape and it was kept in a case in a locked tool box in the back of my van next to a few boxes of shells always some #4 high brass but often some buckshot or 7 1/2 also.
how you carry your truck gun and what your truck gun is, has everything to do with your state laws and how much you want to follow them. as well as your needs.
it used to be in WI you had to have guns unloaded and cased to be legal
in my case the locked box in my van gave me an additional layer of security , it was a wooden box so not a ton but also it was a quick type combination lock I could undo it fast or forget the combo if I needed to , because it was locked and inaccessible from the passenger area it was out of bounds of a search in most cases. I drove that van all over Madison and sometimes for work.
my "need" was mostly all the times I said darn it if I only had a gun with I could take care of that varmint
so mostly I shot 13 stripe ground squirrels with it
thankfully never needed it to get home or for any 2 legged issues but it was there.
I also used to spend a fair amount of time at the in-laws where I would hunt by opportunity if something wandered into the back yard , they were township back then backing up to 2200 acre swamp that was state owned and between Grandma and an Uncle owned the 34 acre around my in-laws 2 there were a few other 2 acre lots that other family lived on on the same road sold from the original 40 grandpa and his brother bought and split in about 1948
back to guns
I had a rifle stolen from another truck and I no longer leave any guns in vehicles over night if I can help it
Now I have a door gun we will call it , this is a 308 bolt action with removable magazines 15 rounds of ammo in a Hornady cheek riser bag with storage 2 mags and 5 in loops on the outside , it is alwasy ready to go , it is a Mossberg Patriot Predator if I need to go deal with something at the farm I am grabbing that as it is alwasy just inside the door and ready to go.
in WI we have to keep long guns unloaded but they can now ride in the cab with you and no case is needed since 2011
If I was thinking the threat more 2 legged my AR pistol would be the go too because as a pistol it can stay loaded in a car since 2011 it is still quite good to 200 yards.
mostly these days I am just carrying my carry pistol if I leave the house with no particular purpose. I have shot a few raccoon that made themselves a nuisance with that.
for the OP if you have the 243 and want to use it I would go the one load and learn it well. if you were buying something a 223 can fill the role of lower cost ammo and less recoil while still taking deer with the right shot placement.
shotguns can be handy if stuff is typically close
decide on what you would be shooting and why and go from there
the thing about reduced loads is unless you go really reduced you don't cut noise that much also why a lot of guys carry a 22mag as a truck gun it is a little less noise , some less cost and still powerful enough for a lot of vermin .
