Ballisticboy's latest activity

Pellets are not drag stabilized and never have been. They are stabilized by the lateral moments about the CG produced by the flare, not...

What about what the land and grove measurements? I wouldn’t be surprised if they went straight up 22lr barrel. As a matter of fact I...

All the above, except MAYBE #2, per Ballisticboy's reply was my point in my reply of "where did the 'extra' lead/material go?" mike

They may look super cool, but it is unlikely that the airflow will see the boat tail, as it has to turn through far too big an angle to...

At subsonic speeds, the nose drag is a very small component of the total drag once you have got an ogive nose of a reasonable length...

There are only three possibilities if the hole in the back has been increased in size:- 1 The new pellet is lighter than the old...

Help me understand.... How can the skirt thickness be the same if the opening is larger? That material, now gone from the opening, has...

The difference in the thickness of the skirt will have little to no effect on the pellet base drag. It will move the centre of gravity...

Can I suggest that instead of shooting 3 groups of old and then 3 groups of new, you try 1 group of old followed by 1 group of new, then...

Not with the right program. ;)

That's a lot of math !

I tried something different for the stability factor. I modelled the projectile with a cylindrical base, i.e. no boat tail. The results...

In Dub-dubs video, he got a believable 0.195 G1. Like I said in my previous post, mine was about 0.160 G1 from similar 1:16 twist 700mm...

I didn't say it couldn't be shot from a 16-inch twist, I said it will start off being unstable, but the level of instability is small so...

Neither Strelok nor the Element ballistic app have the capability to accurately calculate the gyroscopic stability factor. To do it...
