What caused the Rokslide shift to smallest caliber and cartridges?

[Chris in TN]

I started hunting with a 6.8spc in 2006, I think. It took a few years for it to sink in that smaller calibers kill well and that had nothing to do with caliber magic and everything to do with putting bullets where they belong in terms of both anatomy and impact velocity relative to their construction. I still prefer 2000' impact velocity for modern bottlenecks with bullets of 100 to 180 grains as my personal ideal but I have no problems with dropping down to a 77TMK and have seen much smaller things work effectively.

As far as "targeting advice to the average hunter", I'd say that if we are talking about normal hunting ranges, which in reality is under 200 yards, the average schmo that shoots a box of ammo a year would be much better served by a 223/77TMK rig over a 300win mag.

Say it again and louder for the guys in back. And keep repeating it.

Put the empirical data, not the anecdotal data on the table, and we will talk. The majority of the “data” posted here and elsewhere is anecdotal, not empirical. Just because I have great results with blank round and blank bullet by no means makes that data empirical.

Again, I’m amazed when it comes to firearms the lack of understanding about the difference between empirically supported research and anecdotal evidence.

Anecdotal evidence is more along the lines of testimony, "I did it and it worked for me".

591 pages of evidence documented in a specific format with analysis photos, is definitively, empirical.

I'm not trying to be condescending, but it's you that doesn't understand the difference. Thousands of deer documented with pictures is not anecdotal. And even me personally, 200+ deer harvested with the 223. That's about as empirical as you will get in real hunting. If you expect a peer reviewed study by 50 PhD's with millions of data points under lab conditions, that's not realistic for something like this. And by your logic, nothing would pass your test anyway, since nobody has done an empirical study to your standards with ANY round, so the 300winmag is no more effective than the 17 remington as far as scientific studies go.

Hold up, willing to shoot people (who might be shooting back and/or wearing plates) with a .223, but not willing to shoot a deer with one?

That was my thought as well lol. 200+lb psycho with a gun ready to shoot you, M4 is the best tool for the job. 150lb deer that poses no threat, 223 is too small. Logic not working for me.

Slight digression but is there any advantage to the .223 over the 6 ARC? Question being I already have a 6 ARC bolt action in the stable and curious if I even need a .223. Barrel life on 6 ARC is probably going to be around 5000 rounds and recoil is similar.

Ammo is cheaper with the 223. You can use cheap ammo for practice/shooting predators. I don’t have a 6arc so I don’t know the difference in hunting ammo costs but the 223 may be a little cheaper.

For hunting, there’s no practical difference apart from ammo costs and legality.

For practice, the slightly lower recoil and ammo costs is helpful. Form strongly recommended that I get a .223 instead of relying on my 6.5mm Grendel for the S2H course.

That makes sense although I reload for 6 ARC.

Better ammo availability at the average store, and likely cheaper as @Spoonbill said. Realistically though if you already have a 6 ARC, probably not a massive need for you to get a 223. But hey who am I to suggest a guy should have LESS guns?

Barrel life on a 223 can be >10k rounds, so relatively significant for a high volume shooter. I assume components are also cheaper.

The recoil difference isn’t huge. It woildnt be the determining factor for me.

6 arc is legal in Colorado for big game while 223 is not. I think there are some other states with similar laws.

On the practical side, 6 arc will have more recoil, more powder and heavier bullets. Imho it’s still a great choice. Might even have a little more range than the 223

But again, over time, ballistic technology evolved,

That being said, common sense still has to prevail. I would never, ever willingly use something like a .223 to hunt deer, no matter how great the bullet is supposed to be. Doing so is just tempting fate and asking for a poor outcome.

When new information is available "common sense" needs to evolve too.

223 77TMK at 260 yards

This is not an infrequent event.
My personal experience is 5 elk from 120 to 370 yards.
And two nice bucks
One wounded and lost cow elk at 420 as I shot a tad low and broke the off
side front leg. I had plenty of opportunity to finish her off but focused on
my son's bull to be sure he was done. Regrettable mistake on my part
that's full disclosure.
Absolute perfect bullet/cartridge performance in every case.

This is a solid point and shows the fallacy of their argument. Amazingly, I've heard knowledgable, experienced hunters argue that an arrow with the best broadhead is more lethal than a .223 with the best bullet. It still blows my mind.

I’m sure the argument would be made that it typically requires more than one shot in an LE/military situation. However, very very few would be using a 77 TMK. A single 77 TMK to high center chest, and it’s over NOW!

imo, pigs die faster to a broadhead than a bullet. Just my experience with 12-20 pigs as the sample size. Furthest one went 40-50 yards. Shoot a pig with 30-06 at 200 yards dbl lung and it is still alive when you get to it - weird but my experience.

I'll take a gun over a bow any day of the week for ease of use and additional range.

I think we can all unanimously agree that a .223 with the wrong bullet is an abysmal choice for big game hunting.

You’re shooting them in the wrong spot!

Yeah…. Am programed to shoot behind shoulder. Behind ear would be a lot faster!

Jumping in a little late to this latest spat, but wanted to highlight what @Harvey_NW and @JackButler eluded to above.

The information posted in those threads is, in fact, empirical.

The definition of empirical: based on, concerned with, or verifiable by observation or experience rather than theory or pure logic.

Now, if by empirical you mean "peer-reviewed scientific" that is different. If that is the case, then I would point you to 1) the fact that you will be hard pressed to find that for any of the larger cartridges either and 2) there have been multiple studies that prove that "average" people shoot lighter recoiling rifles better than heavier recoiling rifles. Combine that with the undeniable fact that hits in the vitals kill animals, being able to hit the vitals is the most important variable when it comes to hunting. Period.
