I just picked up a converted '03 Springfield in the .220 Weatherby Rocket caliber. I've looked on the internet and found quite a bit of info on this cartridge - basically an "improved" .220 Swift. I was surprised it still has some following and dies, barrels etc. are stil avalaible.
I've loaded for some .220 Swifts in the past and found them to be quite interesting to reload for and shoot. I was wondering if anyone on the forum has any first hand info on this cartridge they could pass along esp. with the more modern powders.
