[QUOTE="Mysticplayer, post: 21216, member: 8947"] Like every overbored situation, there is a point of diminishing returns where a huge increase in powder delivers a small increase in performance. The 22/284 is really overbored. Smaller cases like the 22/250AI will not be that far behind in performance. If interested in the "reg" cartridges, I would suggest the 22/250 AI. This will have the added capacity to launch the heavies out at 3000fps from the longer barrel. This will give pretty good performance out to 1000yds. Going much faster may cause problems as the bullets start to break up. Big downside of the 22 cal is that BC is quite low compared to other calibres. Wind drift and vel. loss will reduce long range performance. Best way to see this, is put in numbers for different BC and Muzzle vel in Ballistic software and see their interaction at longer ranges. Unless there is a specific reason for using a 22 cal rifle, other cal from 6.5mm to 338, will give better performance. There isn't a lot of feedback to your question directly because most will not build a 22 cal rifle if long range performance is the goal. There are better options. For long range varminting, High BC to reduce wind drift will be very important. Good luck.. Jerry [/QUOTE]
