you might as well throw the pellet at the target!!
I also agree.pluss the trigger will be very heavy.177 would be a struggle but 22 even harder.Don't waste your money IMO.Save and get a cheap used gun that is known to be capable of what you want tuned.Then spend the money.Or sell your rifle and save a little?
