I'm not small, 6' 2" and about 220, and I have moved to smaller cartridges for the enjoyment of shooting a bunch. I can do quite well with my 338 mag flinging 250's, but it's work. OTOH, 100 rounds is a relaxing fun afternoon with my 243, 6.5 Creedmoor or even a 308 shooting loads that dupe old LC match ammo.
