Just yesterday took a doe at 90 yards, using 275gr Powerbelt Aerotip in .45 caliber. I have been practicing out to 100 yards with just under 3" groups at this distance. I think they are a little pricey, but I can get them locally without having to order them through the mail. I have also tried the powerbelts in my .50 cal. gun and had good results also. I like them and have had good success with them, they' re accurate, easy loading, and perform great on deer from my experience.
