I just bought a .300 rum sendero. I really like Leupold Mk4 scopes with the TMR ret. I own the 4.5-14 on a tac-.308 now but I am trying to decide what scope for the rum. The rum will be used for long range target and hunting.. I hope to try my skills out to at least 1400yrds with it with metal and with hunting who knows?? maybe out to a 1k??.. thats why Im leaning towards the 8.5-25. is the 8.5 too much scope? or would the 6.5-20 be better? the lowest powers arent that much different anyways.. I shoot 1k with my 4.5-14 and it works but I can deffinatly say that more mag would be nice. maybe someone with some more experience can chime in.
