@CBHUncle Bob, I hear static, the line is crackly, I think I can make out what you say, OK bye, talk soon,
Chris unfortunately all the 243s I have loaded for have struggled to make 2,800 fps with 100 grain projectiles and that is using max loads of 2213sc/ H4831sc and 2299/ H4350 out of a 22 inch barrel.
My standard 25/303 on an SMLE No1Mk111 action will do that and that's loaded to the strength of the action not the ability of the cartridge.
So something doesn't compute somewhere. Dang the old 25/303 killed some game when used within its capabilities with 100grain bullets so there is no reason the 243 can't do the same. It's just that shooters in OZ for some unknown reason stick with the 87 grainers in the 243. Load for the game hunted.
No matter what you say I will always have a soft spot for the 25s and not a heart to accept the 243.
Those that use it correctly are fine but the old 25/303 and 250 Savage are all the 243 wanted to be. It's a shame it got it's capabilities mixed up with ambition but advertising sells and deluded.
