Anyone running the Berger 90 VLD?
I've used them at 1,000 and 1 mile, but haven't shot game with them...yet.Anyone running the Berger 90 VLD?
I have a friend who shoots the heaviest Sierra 224's from a 22.250 Ackley improved. Can't remember the twist and velocity but 1 in 8 is fuzzy in my memory. Great accuracy and puts 7 foot Roo's down at extended ranges.We always need a new toy, right?
Debating a 224 caliber build to run 80-90gr bullets above 3300. Thinking but, not limited to Swift, 22/284 or 22 Cheetah with fast twist 24-26" barrel. There are some who say this is impossible due to constraints of caliber/bullet length/twist ratios. The contention is that if you get a twist suitable to stabilize the bullet length, it works against velocity (<3100) and/or bullet integrity will go to pieces due to hyper-twist above 3100.
I definitely see the logic of these constraints but, i have yet to find a guy who has actually experienced these limitations.
I know several of you guys have experience in this department? is it possible to accurately run the heavies above 3300? What say you?
Note: they make barrels everyday—-barrel life not a concern!!!
Nice rig and neat cartridge! Thanks for the tips! Never thought about the 6.5x47 case but, that will certainly workout!I have some experience shooting gophers with 77 gr Sierra Tipped MatchKings from an 8 twist barrel at 3400 fps. Nitrocarburized barrel and HBN coated bullets. The bullets grouped reliably out to 400 yards off the bench but were all over the place at 550 yards (the end of our range). Then Hornady came out with their radar data showing the tips melted on the way to the target. I had a similar story with 55 gr Ballistic Tips. I still have hundreds of AMax bullets with the melting tips Hornady warned us about. I still shoot the 77gr TMKs but with the Valkyrie at much lower velocity. What I am trying to say is that some bullet tips will melt at extreme velocity and accuracy will suffer. Having a couple of rifles chambered for wind resistant cartridges can save a trip. Choose your bullets carefully.
Photo is of a 6.5X47 Lapua necked down to .224 and blown out to 40 degrees it has Swift volume Small rifle primer. 80gr Sierra HPMKs shown. Reloader 17 would get you to 3400 fps when I was satisfied. That barrel is toast. Sightron 10-50 X 60 for 500 yard shots.
Would certainly consider others but, that bullet is what I had in mind for this Project.I've used them at 1,000 and 1 mile, but haven't shot game with them...yet.
Psi,and blown primers22 creed 28 inch 1&8 . Can't go any faster before I start breaking triggers on my 3rd trigger tech now
