Not always. The gun should be selected for the purpose it is to be used.
No. The .243 is a larger calibre, and the parent case is the .308 Winchester, necked down to accept the smaller projectile. It's considerably more powerful than the .223.
As far as diameter, it's smaller. But the .243 is a necked down .308 cartridge, giving it a longer overall length. As far as grains go, you can get a much heavier projectile in the .30-30, but you'll have better performance at range with the .243.
The .243. It's basically a necked down .308 Winchester.
Don't know about the 243 carbine but the serial numbers for the model 100 go up to 263170 on the site I use to check dates. That number sounds about right but the model 100 was made in a .308 and a .243 with the .308 being the majority.
no- very much a center fire cartridge. It is the .308 cartridge necked down to a smaller (.243) bullet.
Short action. Based on the .308 Winchester
The parent case of the .270 is the .30-06, necked down. The parent case of the .243 is the .308 Winchester, necked down. Aside from the larger diameter of the .270, the .270 has a longer case.
.243 is a short action- it is based on the .308 cartridge necked down- and .308 is a short action. 25-06 would be a long action (parent cartridge was 30-06)
A semi auto rifle from the early 70s made in 243, 284 and 308.
The 08 is referencing the parent case, the .308, necked down to accept at .284 diameter bullet versus the .308 caliber. Other variations of the .308 case: .243 Win, .260 win
It is: 508 minus 243 = 265 greater than 243
30-06 because it's a bigger round than the .308 although it might travel slow it has greater impact on the target
