I was finally able to get a water jug test done with The whelen and the 200 gr Hornady.The muzzle velocity was 2780 fps. @68degrees. Distance to the jugs was 10yards,the bullet penetrated 5 jugs and weighed 123.0 grains.This load using Imr 8208XBR gives excellent accuracy and good speed out of my 700 classic Whelen. Lee
