.308 or .338?

[Delfuego]

I believe you are thinking of the wrong .338.

You know I am! I was thinking 338 Lapua! Not Federal. I thought you were gonna buy and build Glenski's 338 lapua stuff

308 hands down.

The 338 Federal cant push any decent 338 bullets fast enough. Past a few hundred yards it would be like lobbing in artillery shells.

I have had to opportunity to shoot, sight-in and play around with a 338 AR-10. The bullet drop at 600y was considerable; way, way more than 223 or 308.
