A speed of 2250-2300fps is entirely feasible from a 35Whelen. A mate complained of a lack of expansion from the 310gr Woodleigh, but then chronographed to find that his load showed high end 1800's fps. Bet you kicking them out the barrel at 2200fps would solve his problems. The Woodleigh RN's is simply superb at expanding wide whilst retaining weight.
