Well, the Palma Matches are for 308's at 800, 900 and 1000 yds, open sights only...that being said, they use 155 gr bullets...do not know what the energy is from 155 @ 1000 yds but it can't be much...

Need SD to carry the energy to long distances...in 30 cal, probably 200 gr is best, that is what I shoot in my 300 H&H at elk, but the 165 gr is great on deer at any range..
