Ballisticboy replied to the thread How to figure this...?.Simples. Because I read it on this one first. :)- Ballisticboy reacted to Scotchmo's post in the thread Will the 7mm That’s Being Introduced by the Wolfiek Group Prove to be Better for Competitive Shooters? with
Like. A slightly shorter 106gr 7mm will work well in the 1:14 twist TJ barrel... - Ballisticboy replied to the thread How to figure this...?.Approximately 11.7 degrees outside, about 12.1 degrees internally.
- Ballisticboy reacted to Motorhead's post in the thread Will the 7mm That’s Being Introduced by the Wolfiek Group Prove to be Better for Competitive Shooters? with Like. 7mm would be a SLUG ONLY caliber as projectile lengths are long that also require a somewhat fast twist rate to stabilize them.

- Ballisticboy replied to the thread Ballistic Coefficient: A Real World Example.Not really semantics, differentiating between the two is very important if you want to understand what is happening. As for the 100...
- Ballisticboy replied to the thread Ballistic Coefficient: A Real World Example.You are talking about accuracy, where BC will have an effect. I was talking about group size, or precision in US nomenclature, which is...
- Ballisticboy replied to the thread Ballistic Coefficient: A Real World Example.Unless you are shooting on a windy day with the wind varying a lot, BC will not help your group sizes, that is much more complex.
- Ballisticboy replied to the thread Max flight range for an airgun pellet or slug..Both MERO and the original Chairgun will give maximum ranges.
- Ballisticboy replied to the thread Strelok Pro Questions.GA is not a suitable drag function for slugs, particularly at speeds approaching 1000 ft/sec. The BC quoted by FX may well be based on...

- Reynolds Number?!!? Scalable Behavior?!!? Aerodynamic Hysteresis ?!!? You two make my head hurt!!! Keep it up and I am going to go...
- Ballisticboy replied to the thread Do pellets tumble ?.This is why we want the matching Reynolds number where possible. Many tunnels work by using accelerating or slowing air speeds to...
- I made this mistake for too long also. Read Miles thread on aerodynamics. Drag force could mean a few things in common thinking but in...
