Sorry James the 270 aces the 308 for energy, at 300yrs the 130gn 270 bullet has around 250lbs of energy more than a 150gn 308, plus shoots a lot flatter. It is not the classic choice for hill stags for nothing.jameshodgson said:I would suggest that the 6.5x55 and 260 rem are a good starting point for large reds at range on the hill. 308 and 30-06 are probably the more common choice, with 270 and 25-06 in the middle.
Must have a good twist rate.Shot placement is the key factor as to whether you kill a stag cleanly or not. I have just come back from Scotland where I shot four stags, largest was 18st 6lbs clean in the larder, all with a .243 and all with one shot per beast, i was using 105g SN Geco's factory ammo. I spoke to the stalker before hand and said I had I only had my .243 as my 308 is not shooting well since I had it moderated and I have not had a chance to get it sorted. I expected him to say use the estate rifle 25.06, he asked me to shoot on the range and was happy for me to head to the hill with my 243. I was rather apprehensive about shooting big stags with a .243 but the stalker was telling me how all his father shot was a .243 and he had been a stalker for 40yrs. I am not saying it is the perfect hill rifle by anymeans or the hardest hitting hence I have a 308, but do not underestimate what a 243 bullet can do when it is put in the right place.
As `irishgun` will confirm we have taken many Red and Sika stags in Eire even with the .22/250 during the bad old days between 1972 and 1993 until the ceiling was sensibly lifted to .270 , the often maligned .270 and the venerable .30-06 are ideal for big stags.A 243 can get you into trouble on sika/red stags ...not a fan of the 6.5x55 ... the 270 using 130gr ballistic tips or SSTs is ideal for these hardy animals .
30,06 is a tad better . there has to be enough wallop to take the air you of there lungs .
