Been playing with numbers for an impact. Kind of wish UA didn’t talk me into a 22 cal. I’ve owned a .25 cal marauder 50 fpe w/ 33.95 grain JSB pellets. Wanting to try the 33.95 slugs from JSB in .25 cal or should I still with what I have?
.22 cal slug vs .25 cal slug

Are you wanting to stay at the same length, go longer, or maybe shorter? If you are staying at the same length and already have a probe, then you need a barrel, transfer port and magazine. If you are going longer or shorter a complete barrel kit and magazine would be needed. Hope this is understandable.

I've got my 22 impact at 75 fpe in 22. If you use the pin probe already you put the 25 sleeve on it and I was under the impression it's a liner and mag swap to get where you want if your mod can handle 25. I never did enough research to see if the liner gets thinner and still fits in the barrel tube or if the barrel tube gets a larger id for a 25 liner mandating a barrel kit. Somebody will correct me if I'm wrong.

Does your Impact have a slug liner ?
Maybe try some. 218 34gr H&N Heavy slugs.
Your Impact should easily shoot those 1000+fps

I have slug liner and slug power kit. I’m sitting t 16 on my macro wheel 5 on my micro wheel. 145 bar on my reg. 850 fps right now. I plan to see if I can get up to 950-1000 fps. I just wished I’d bought a 25 cal. Just found a place to shoot a few ground hogs at a farm
