I'm planning on a new prairie dog rifle. I'm looking at the .224 Valkyrie BUT from I've gleaned from the internet it should be a 1 in 7 twist or 1 in 8 twist for 50-60 grain bullets. Would a 20 inch 1 in 8 twist Wylde do just as well with 50-55 grain bullets out to say 350 yards?

I have had 4 Valkyries. Two 22" with 1:6.5 twist and two 20" with 1:7.7 (all ARPs) Three of the 4 have true SAAMI chambers which are noticeably tighter than the original chambers that had several errors in it. I have never heard of a Wylde Valkyrie chamber. I use the 1:6.5 twists for 90grain bullets for long-range precision. From my experience, if you want to get full BC potential, 1:6.5 is better than 1:7. I use the 1:7.7 for hunting coyotes, varmints, and hogs. If you are using a 1:8 twist, 80 grain bullets will pretty much be your upper limit. Don't believe Berger's claim their 85.5 Hybrid are designed for 1:8. There are plenty of good .224 varmint bullets. However, I use 55 E-tips because they hold together and are very effect on hogs - even big boars. I'm using 30 grains of CFE achieving 3450 fps. They really smoke coyotes. Every 'yote I've shot just drop to the ground - no spinning or yelping. 220 yards has been my longest shot using night scope off sticks. The Valkyrie is a great cartridge.

With the same bullet, the 224 Valkyrie can get about 300fps more than the 223 Wylde from the same barrel length.

The 1:8 twist will stabilize anything up to 77gr.

I found the Federal 60gr Ballistic Tip to be accurate in all 4 barrels, 3100 fps mv. I haven't tried the Hornady 60gr V-Max but it must be good - it showed up on ammoseek.com and was gone in less than a day. Sierra has come out with Valkyrie ammo using a 69gr BlitzKing which may do better at longer ranges and with wind.

I know it's a cast but I shoot a 62 gr in a 1-12 222 and 1-12 22-250 , 220 Swift etc have been managing 55s to 4300 fps for about 60 years . Modern bullets unless you have to go unleaded a 1-9 should handle 62-65 gr pretty well .

I found 3 1-7 twist Valkyrie barrels all 6 groove. 1 1.6 twist 5R QPQ and NO 1-8 twist. I'm going with the 1-6.5 twist and see how light of a varmint bullet I can push out of it. Thanks for all of the testing you've done with the Valkyrie and 6.8.
