Airmarksman .22 cal slugs

Has anyone used the hollow point? I see several comment and post about the 40.1 grain slugs, but I'm curious about the 33.1 grain .217. I purchased my M4 Impact sniper shooting 950 fps with the 33 grain slugs. IDK how many shots or my ES. My chronograph just arrived. Still awaiting my tank for top airgun tank and optic choice. Currently it looks like Utah have me on my macro power wheel at 16 and the macro at 4. I like to be 140ish on my regulator.

UA was out of stock of the .218 33gr. So I ordered the .218 34gr Corbin slugs from Pyramyd Air which are the exact same except for the weight.

Here they are compared to the 34gr H&N Heavy that I have been shooting.

I am shooting them from my DRS 22 700 @990 fps. I have the reg at 162 bar.
They seem as accurate as the H&N, but I'm skeptical that they will expand as well as the H&N heavy slug.
I haven't made time to shoot them much to find out.
This late in the summer the pdogs are very cautious so I have been using my 223 Remington or 204 Ruger for those longer shots.
