there are a couple options in the .50 caliber game, as paintball Arkansas said, the eNMEy50 is one of the retail options for a true .50 caliber gun and will handle CO2 ok. Spyder has .50 cal markers in a couple different versions and Tippmann is now has the FT50 which is a FT12 with factory installed .50 cal conversion kit, but the marker is sold as a rental gun, but I am sure a local dealer could get his hands on one for you.
Factory built .50 Caliber markers do tend to offer better air efficiency than .68 caliber guns with conversion kits as long as the paint to bore match is close.
We offer conversion kits for Tippmann 98 & FT based markers and the older style GOG markers (bolt out back). We also offer markers with our conversion kits installed. More info can be found on our website.
On the impact question, Yes .50 caliber is about a 1/3 of the impact, but you have to keep in mind the paintball itself when considering this. Markers like the low pressure GOG style guns generally can shoot a more brittle ball and therefore the impact is even less. The blowback markers are a bit harder on paint and require a less brittle ball to prevent breach/barrel breaks and the harder ball breaks with a bit more force.
Splatmaster is a decent choice for back yard play since it does not require an additional air source.
Hope this helps and Merry Xmas.
