Someone left some 28.5 grain Dae Sung pellets at the range the other day. I think they are for the Korean PCP rifle. I did not try it but I think they are too long for PRod magazine. I have a single shot tray. I shot 18.13 and 14.3 at the same time with the same point of aim. The 28.5 pellets are a wee bit tight loading in the PRod. I think they would be good rat killers..
