Not sure about the .177 variants, but @$p00kygH0ST has been shooting the .22 17gr around low to mid 800fps and getting excellent expansin along with accuracy. Could you post a pic or two of the slugs?
Anything above 740 gets it warping and expanding. Anything above 800 opens it up, above 825 gets mushroomed.. 920 is the max I've pushed one this far. I have a DRS and Barra250z currently on the way, I plan on using the 19 Or 21gr LDC at insanely high velocity as my main projectile for squirrel and rabbit. I know the Drs will be fine as the superior 1:24 groups them better than pellets in my notos and crown. I'm a definite believer.
I've checked out the selection of slugs for Griffin in 177 and does don't have LDC balls in them. I'd like to think that they still expand a lot, but their HP isn't too big from the looks of the website.
Im an idiot. I thought you were asking me. Didnt realize wanted the 177. I don't imagine there's enough room. I think the poly ball in .22 is damn near 3.5mm that leave walls so thin in a 177. Even though the LDS are way longer than comparable slugs of their weight.
Let me know if you do try the 177 of other types form Griffin. Id like to try some in my Huntsman.
I may give them a try, I got my sample packs of .177 from VK to try on the new p35x when it gets here.
I'm sitting here with a huma reg'd p35 in my cart already. Ive been debating between that and an AEA challenger with a huma reg
