I guess it all depends on the rifle:
338wm: 4+1 (5 rounds in rifle), 6 in hunting vest, 1 in shirt pocket= 12 rounds total
30-06: 6+1 (7 rounds) or sometimes just 6 in rifle, 6 in vest, 1 in right side shirt pocket: Lucky 13
New Tikka T3 superlite 7mm rem mag: 3+1 in rifle, 6 in vest and 1 in right side shirt pocket: 11 total
