Here' s a compairson picture of a 416 caliber 400 grain Hornady RN fired from a 416 Rigby with a muzzle velocity of 2600 fps and a distance of 45 yards.
The bullet on the left side shows the top and side view of the bullet that passed through the heart of a 300lb bear. I dug this bullet out of about 12" ground behind him. It took a step backwards and dropped in it' s tracks. The recovered bullet weight 298 grains.
The bullet on the right side shows the same views but was dug up from a dirt backstop . This bullet was fired from appoximately 50 yards. Same 2600 fps velocity. The recovered weight of this one was 265 grains.
Both mushroomed well and somewhat alike. I do think the bullet that took the bear lost/shed alot of it' s weight when tearing into the ground. *note* the lead is pitted
I am happy with the performance of this bullet and it' s outstanding accuracy.
I just wanted to share this with y' all.
