Thank you! Nuff said.Are we to think we need to justify the 5.56, sibling .223 and the AR? And be bracketed into a very limited hunting scenario so an antiquated 30-30 cartridge and common lever action can be debated to give the 30-30 a potential edge? Don't go outside the Lines so OP can maintain some ground to stand on? Well, I'm moving my fingers and toes and not playing by your rules.
Who says a semi-auto 5.56 is restricted to Hunting Bamby at any yardage. Let's not play slap and tickle with the hunting scenario.
How about multiple BGs doing a home invasions? ARs have been used successfully several times. How about the Church shooter that was challenged and chased off and persued by a guy that got his AR from his house. Neither of these type events would be better servered by a 30-30 which is most common in a lever action which generally is slower to cycle, less accurate, less initial capacity and slower to reload. There's a lot of odsurdites being tossed by OP. Sure, all types of guns are used to attempt to discourage home threats. BUT the bigger and practical reality is what do "we" and OP use? Is his choice a 38Spl with 5-7shots and that is all he keeps available? Does he argue for what he doesn't do himself? Poachers kill elephants with AKs, a 5.56/.223 AR capable of killing a deer if a person desires to do so.
The AR is for repelling boarders/stopping Threats and does so up close and well beyond 150 meters. OPs question is actually silly if you boil it down to where it really matters (and Bambi ain't it): Your going to do battle, you and your opponent can chose either a 30-30 or a 5.56 semi-auto AR: Pick and answer. NO: well if we're limited to 150 yards, blah, blah blah. So let's not play hypothetical and very limited scenario comparisons with two totally different calibers, desighned fordifferent puposes and use in different platforms.
There's a dozen better cartridges for deer hunting. Even with the newer 30-30 poly point tip ammo it's still a ballistically poor choice even at your limited 150 yards: hit the plate or POI within 1.5 MOA of POA? Yeah, there's the plinking thing, target thing, varmint thing and competition stuff but that's not the reason I own ARs. And yes, most of them are true gas piston and not piston hybrids or DI.
We could use a Poll: Do exclusively you use a 30-30 for deer hunting every year? Yes or No. If its still the greatest thing since buttered bread, there's no reason to use a "lesser cartridge". 30-30 Is hanging around only because a. The average joe who wants a lever action buys .22LR or 30-30, other catridges are either not as common or too powerful. b. There's a crap load of them out there since 1895. c. Optics that the common man could afford weren't available for at least the first 1/3 of its production. d. It's a mild 30 caliber cartridge. However, anybody that wants accuracy out of the box chooses anything but a lever gun, the Bands, forestock and fed tube are inherently adverse towards accuracy but people didnt care much because the cartridge was so limited anyway. Top ejection is a optics problem for some models, your not going to get close to bore axis. So if we compare the 30-30 lever action to other deer cartidges and actions the best that can be said is its adequate at closer ranges and the ever popular: its light and handy. You might want to check actual db level for the 30-30 and the 5.56 (which is slightly lower, indoors and without ear protection both will hurt.
How often do you see 30-30s in Camps or when you cross paths with other hunters? Last time I saw one was taking the Wife's Grandparents out for a day hunt in 95. One 30-30 Winchester with buckhorn sight and a sporterized 30-40 Krag. We had a nice easy day and it was their last hunt. Lol
Life isn't a Zombie movie but its not a TV western either. There's better tools for Bambi and BGs than the out classed and dated 30-30. YMMV, so I'll let you go back to your story plot. Lol
