That I cannot say. I bought the mold nearly 40 years ago to shoot from a Ruger in case bullets got hard to find. Imagine that ! At that time you had to sign and show ID to get 22 LR ammo, what a Charlie Foxtrot. Took 30 years to get John Q Public to pull their heads out. Now they are putting them back. Anyway, I found the load I mentioned made 1 hole groups with that rifle, not much recoil or noise. I shot a little buck at 180 yards, he just jumped like a fly bit him and looked around, went back to eating. I thought I had missed him, put in another shell and looked through the scope- he just trembled all over and dropped . When I field dressed him (I always eat the heart that day) I held up his heart and you could see through the hole. Several more deer and smaller game followed, I just never felt compelled to go farther. I would say that hard cast and with good lube you could get close to 2000 fps if you want to, I imagine it would expand more then. If you decide not to go with the HP I recommend you look at the Lyman 385 gr FB, It used to be the gold standard to hunt with and is also extremely accurate. You get double cavity mold there.
