I've loaded a bunch in 308 Win and 7.62x39 (the 110 grain's mostly). Accuracy is not as good as jacketed bullets, but they shoot plenty straight enough to have fun at the range banging the 100 yard gong during off-hand target practice. Rule of thumb I've found, is that whatever your rifle will group with jacketed bullets, double that, and that's what I can get out of the Frontier's.
