Brad,
You're up!

I'll go work on some popcorn....

Stick & could chase tails all week, talking ballistic coefficients & sectional density, maintaining sub MOA @ extreme distance & the effect of the lunar cycle on the rotational speed of a streamlined projectile.

What it comes down to are two different applications of the hunting rifle. Mine is more traditional, the hunting of pronghorn, mule deer & elk with shots of 300 yards or much less if possible, while having rifle, ammo & mindset prepared to take a 400+ yard shot if conditions demand & I feel I can hit it.

His discipline is more modern & complex, the shooting of coastal blacktail deer @ distance from the high ground, employing a well rested rifle, laser rangefinder & a repeatable turreted scope.

Now, his black bear hunting falls more into a spot & stalk mode. But he, I think, will be first to admit that the 2 calibers under discussion wouldn't be anyone's 1st choice.


Pass the popcorn.

First it's O'Connor and secondly,he was King Of The Dinks,during The Age Of The HOGS. Folks like Elgin Gates were lightyears ahead of poor JOC,during the very same era. JOC could simply right purty,which enthralled the clueless,by his outpouring of fluff. I'm far more Meat & Taters and am at ease denoting things how they is and will leave purty to them who dabble in fluff.

All chamberings change in their relative merit,due to boolit selection and it never doesn't not amaze me,as to how many reliably miss that and by a mile. One's rifle doesn't get heavier,longer,lose balance/handling nor are there any other concessions inherent in operating with a clue. Many are under the illusion that they gotta boldly take gear to Star Wars Technology,to eek the goody,which is very much not the case. Those gross misunderstangings,coupled with being totally devoid a ballistics clue,very often leads to rather amusing conversation(s). Shooting is only "hard" for those who don't shoot and it seems noone shoots anymore.

Just as few would take a great knife and dull it upon rocks before heading out on a Hunt,or cut seams in new boots or have their pooch chew holes in their new rainwear,it's curious to me that the masses enthrall in doing same to a rifle and upon many levels. With but an inkling of an understanding,it is very easy to field a platform at it's maximum inherent potential,as opposed to leaving 85% of that availability benign by default. All less concession.

Now those constants being said,I'd state plainly that the SAAMI 243Win is a literal GIANT Killer,as typically offered over the counter. Further,it is a great first choice for tipping Critters over at distances,that'd make most more than a leetle squeamish. Why is that? Simply due to projectile availability,within said bore sizing. When a 270Win's Trump Card is to "nearly mimic" 243Win performance,such things is enlightening to them with a clue. I'd liken it akin to chest waders that keep you almost as dry as hip boots,but not to the depths of the hippers. Such factoids leave little to get horned up about,whether it Theory or Application...yet the cats in the chest waders will never quit grasping at straws,as faint hope to satiate their cluelessness being "on purpose".

I dig it when folks start "telling" me stuff,factored by their "experience" and "results". Was looking forward to some scattergun fluff too.

You guys are on fire,keep at it!

.243 Winchester is a nice round but I'd take my 6mm Remington first.
A little faster and a little purdier.
The one I'm in want of lately is 6BRX.

I shoot 6mm and 6AI both,with equal disdain. They are hungchow in a short action and if going long,why form to less case capacity when the 6-06/6-06AI are so viable?

In a s/a the 6-284 is a better mousetrap than anything on the Mouser hull,due to COAL latitude...which brings a guy full circle back to boolits. A rifle can be no better than it's boolits and when COAL constraints preclude the good stuff,chamberings so plighted are easily passed upon,in order to get to the good stuff. Some boolits certainly rate building a rifle around and the aforementioned 105 is assuredly in such ranks.

The 243AI is 6MM Rem case capacity,with SAAMI 243Win COAL latitude. Win/win. The BR or any of it's Wildcat spawn,has never called me,mainly because I can't forget that I like speed. Same as 6mm's on the 223,22-250 or the like. Perhaps a PPC,if forced to suffer short range Bench Queen affairs. Very nice BC's at meaningful speeds,make a guy hate everything else.

I'm done with tight necks and long barrels too.

Simple, to fit an AR magazine.
Those short, fat boiler rooms get it done in that platform.
Also competition bolt guns are proving that the design is worthy.

Might as well go full-meal-deal

.300RUM... Best all around cartridge for real men/women or kids....

Made me think of this :

I've no interest with a .473" or greater boltface on a '15. Go AR-10 of course and you've 2.800" or better COAL to work with. I'd much rather have a 243 or 243AI on a '10,than any 6mm shoe-horned into a '15. Fact is a "short" barreled SAAMI 243Win on a '10,is a rather wicked machine. I'm not hip on feeding self shuckers with brass that's $1 a pop,while polishing a turd to boot.

I'd hang pics,but someone would wanna pay me to place them in a magazine. Pun intended.

The 6BR/X as a LR belly gun in F-Class or similar,are typically laden with very long spouts,many of which are 28" if not 30". Pass the 22" 243/243AI and hold the fluff.

If it were shortened to 2.500" or so,like the lopped H&H spawn(264Win,7mmRem,270Wby,7Wby,etc),it'd be sumptin'. As it sets,the 300 Ultra is very COAL stingy,beings it has no wiggle room to work with as a repeater fed high BC's. Which of course is part of the appeal in the 338Ultra and it's shorter hull.

Folks is to quick to fixate headstamps,which mean far less than boolit selection. Very easy to coax a .625BC kissing lands from within it's box,ala 7mm RemMag on a 700 and it'll always steal the show,with 3100fps from a 24" being a breeze. It's the free-est of lunches,regarding relative "Oooomph",residual speed,wind bucking and bang for the buck,on top of minimal felt recoil.

The big picture escapes most,if not all.(grin)

That's the allure. The Grendel and/or SPC based 6mm's strain to reach 2800 which isn't bad. The 6BRX is over 3000 with a 20" barrel and will feed through an SPC magazine. This is fairly new, there two firms offering 6BRX for AR15, BR Armament Technologies and AR Performance.
I like the AR Performance 6BRX bolt/BE system better than what BRAT offers (Olympic system).

AR308 is a different animal. I would probably want to launch 6.5's out of that beast.
