.25 700 mm Superior Heavy, First Impressions

Going to keep this short but first impressions are good. Is it better than my Slug A liner? I think so but it's not broken in yet so going to reserve judgement.. Maybe 75 shots through it so far. Posting pictures of tuning with 33.5 and also some preliminary shots with 38.5 gn slugs.
