Erik,
Long begins at 200cm

I'm only 191cm something tall-You have no idea how lucky you are, shorter people seldom get back problems and are more agile

Hopefully I will shrink a few cm with age

375 H&H with such short barrel must loose a lot of velocity. Why not rebarrel to 404 Jeffery or 416 Rigby and get a 9,3X62

Cheers
/Johan
