If you think the lube on the Ballets is sticky, you should try the lube on the Hornaday PA 245 gr conicals. The bullet has stuck to my index fnger once or twice...lol

I'll bet the 275 gr. bullets you have are the T/C Maxis. I think the best Maxi accuracy for 1-28" twists is the 350 and 370 grain -- but only out to around 75 yards. I never had any 100 yard success with any T/C Maxi of any grain size in that fast twist.
