You make some valid points BUT I personally have seen to much game wounded with the 243 to deem it worth while as a hunting round.
Here are some examples
243, 87gn federal blue box ammo. Bullet passed straight thru a big western grey kangaroo zero expansion.
Hand loaded 87gn VMAX, 3 chest shots to dispatch a mature Billy.
Hand loaded 95gn nosler balistic tip. Pig 1, 30kg weight bullet pass thru zero expansion, pig 2 same bullet exploded on the hide of a 50kg pig not mud encrusted large superficial wound. Pig 3 same bullet actually worked.
The problem with the 243 in Australia is most people select the wrong bullet for the game hunted. Most like the 87 grainers for general use on every thing and suffer failures. Loaded with a good 95gn SST or 100gn round nose it would probably be a fine cartridge within 200 yards for medium game but the majority of people don't see this.
When it first came out in a blaze of glory with Winchesters advertising it was supose to be the best thing to come down the turnpike since buttonup boots and sliced bread. It didn't live up to the velocity chain that Winchester made for it and they lowered the velocity.
I have loaded for a couple of 243s for friends working up to max charges and in no case could I get anywhere near the book velocity
87 grainers managed 2,900 fps in a tikka t3 light and just a tad over 3,000 in another rifle. The 100 grainers were struggling to get 2,800fps out of either rifle,closer to 2,700fps.
Book velocity for the 87s was 3,300 and the 100s were supposed to be 3,000 fps, a big difference.
I was at the range and a gent was trying out his new Sako 243 with factory Winchester 87 grainers and Hand loaded 87s. The factory loads chronoed at a bit over 2,800 and the Hand loads were only fractionally better.
My case is why would anyone want to use a cartridge that can't live up to its claims and advertising hype as a hunting cartridge with projectile that just don't work on their chosen game.
The little 250 Savage and mild mannered 257 Roberts have been around for a lot longer than the 243 and have been doing a better job than it for years but Winchester advertising killed them off and people started using the inferior cartridge because Winchester convinced people this is what they needed.
If you want to use a 243 by all means use it just stop asking me to finish off your wounded animals, I have done it to many time for hunters that are great shots.
One person I used to hunt with had a nice Tikka T3 lite in 243 that would shoot tiny little groups. He was give an old M17 converted to 25/06 that he asked me to look at. I glass bedded it, fitted a Timney trigger set at 2 pounds. That rifle grouped 2 inches at 200 yards. It was over 2 pound heavier than his beloved 243. After using the 25/06 he left the 243 at home and stated the 25 was far superior and killed how he was led to believe the 243 should. He has shot a 14 point red stag and a mountain brumby with it using federal 117grain blue box ammo and said if he had the 243 at the time he wouldn't have taken a shot at either.
Now you can understand my strong dislike for the 243, I just don't trust it and why I love my 25s for use in Australia, the 25s just seem to make Moe sense to me.
