What is the difference in these two? They seem to be about the same in velocity etc. Any one have any experience with these? Is one more accurate, etc. I want to rebarrel a .308 Remington 700 to a faster .223 type of round for coyote hunting and occasional target shooting. Thanks.

The main difference between the 2 is that the 224/6mm (TTH) is designed with a fast 1-in-8 twist to stabilize 70-80 grain bullets. It will send them 3700-3800 fps. If they were both made with the same twist the wildcat would probably have a slight velocity edge. My .224/6mm likes the 75 grain AMAX's at 3500fps.

Good Hunting,

I believe the TTH is about 10% more capacity over the Swift. I wanted the TTH too until I realized the higher price for a wildcat chambering, dies and the fact it will (with the correct 1-8") eat normal bullets for breakfast. I'm cheap so I did the swift thing, no regrets.

Thanks guys for the info. Im cheap too. Just might get the 6mm Remington in a 700 VS and be happy. I have one of the 243 WSSM's on order now in the Win M70 for a walking varmiter. 6 lbs!!!. See how I like that first.
