Hi! I was wondering what velocity is neccesary to cause hollow point pellets to explode or expand on impact. The reason im asking is I recently tuned my .22 pellet gun, with which before the pellets never expanded in wood, now with the tune they seem to explode and disintegrat within the wood. (I cut the board in half and examined the pellet fragments) So, what fps would my pellet gun have to be firing at atleast to cause such carnage. Super excited to go hunting with it.

Thanks, Ryan.

It also depends on what you are shooting into .... Wood is quite hard and causes pellets to expand that normally wouldn't in tissue....

Shoot a ground squirrel at 900fps with the hollow point. You'll see good expansion on autopsy!

Hmmm...expansion of the pellet or the squirrel?

I wonder how one could make their own ballistics gel? Maybe using Jello?

The Predators were working well for me on ground squirrels - heads and shoulders at an MV of 880fps HW97 .177.
Much also depends on where in the animal you hit. through the shoulders might expand better than a rib and lung shot - even better maybe than a head shot, depending on the animal's skull thickness,
Crossman .22 HP's according to Bob's soap tests, are VERY tough. I'd expect the .177's to be tough as well.

It doesn't really expand in all of the tests I've ever seen.

Ive made the ballistics gel, and ice found that it shoots about an inch on average into pine wood with pointed pellets, however im still wondering what depth into the gel I should see for certain speeds? I also made it out of jello and am wondering if that is the same as the gellatin gel, such as the density and viscosity due to all of the sugar?

I don't think that pellets are any diff. then handgun hollow points, and it's long been felt that anything below 800-850fps does not expand reliably on soft targets.
