Any update on when wildcat bullets will be in production?
Wildcat has been up and running for several months. They are only producing the 200g 7mm, but will expand to other calibers as soon as they can meet demand of the 7mm's.
Here's Paul's email.
What rate of twist is needed to stablize the 200 grain 7mm? Will a 1 in 10 do it? Looking for a bullet to shoot in my 7mm ultra. Thanks
I don't think so.
A 7RUM will probably stabilize them in a 9" twist, but will probably need a faster twist for anything with less velocity.
You are probably going to need a 1:8 twist for something that heavy in this caliber. That will be an awfully long bullet.
anxiuosly awaiting a 375 bullet for my 375 tejas.
Conventional wisdom breaks down with the really long bullets. Because they are so very long, the lead core and thin jacket make them susceptible to torque. You want to avoid over spinning them. The RPM limit is greatly influenced by the number of lands and grooves.
You can use "advanced search" to go back into the archives about 5 years when they first became available and see how the RUM people fared and what twists they were using. You will also find the velocities they obtained. As I remember it, the 9.5 twist people had some successes and some failures but nobody with a 1-10 succeeded.
This is an area where you really need to do your homework beforehand
