@ankiwi Totally fine. Maybe just google image search: "Remington 870 shotgun with scope", and you'll see a few images pop up with people using them or just an image of the guns on their own that you can slap on there as well. There are even videos out there you can find of people using them to target shoot at 200+ yards.
Also, for anyone curious, it looks like based on the first couple pages, at some point he gains the ability to buy new firearms, as he's looking like to hunt the goblins he's sticking with Remington and using the Model 700 in those shots. Curious what caliber, as it comes in a lot of variants, most likely I would guess either the classic .223, the .308, or the Lapua .338 Mag. My guess would be one of the later two, as the .223 doesn't really have a huge range advantage over a solid slug round in a 870. Maybe 300 yards consistently, 600 with a good amount of skill, and up to 1000 with a very high level of skill and luck. It's MUCH cheaper to fire though, so maybe if hunting Gobbo's it would be the better option. The Lapua though can go through body armor at 1000 yards consistently, and with lots of skill and luck can hit up to 2000 yards or so.
Cost wise though, it's no comparison, Lapua Mag's are like $6.50-$10 a round, .223 is like $0.60-0.70 a round, so like less than 1/10th the cost. Shotgun Slugs and Shot both are like $1.00-4.00 or so on average, depending on what exact kind you're going with, if it's sabot, what material, rifled or not, etc.
