I own RAW’s in .22 and .25. Thinking about having Martin tune one for me in .177 but I want a high power gun like my others. What experience do you all have with this platform shooting heavy pellets or slugs in .177?
If it's set up with same valve sizes as 22 or 25 it shouldn't have a problem pushing heavy pellets I haven't tried slugs in my 25 so I couldn't tell you how they perform
Smaller bore = less area, so ....... Longer barrel of @ 24" min ( or a full length LW blank ) If barreling with something else 26-28" IMO is not unrealistic.
