Hi Dr Ray, I have used these 450gn bullets and have had very poor performance with them from my 416 Rigby.
This bullet was removed from a scrub bull. The Bull was hit at a range of approximately 50m side on and the bullet hit
just behind the front leg. It broke a near side rib and through the chest
cavity through both lungs and lodged in tissue just on the other side of the
off side rib.
The bullet only hit a rib and as you can see there is nothing left other
than jacket down to the cannelure.
I tried the same bullet just recently with the following result.
I shot a Micky bull (young scrub bull) in poor condition at 142m(ranged).
The shot placement was not real good and hit him too far back. The entry did
not hit a rib and I found the bullet in the stomach.It also did not mushroom but folded the jacket back in ragged pieces. I must say it was poor performance as I thought at that range with a little less velocity it would pass through given that it only had
chewed grass as an impediment.
I have now lost all confidence and will not be using these in my 416 Rigby.
My communication with Geoff from Woodleigh has not been as positive as yours.
"Hi Neale,
Thank's for that, obviously, we will have to do some gell, and field testing
to see what is wrong. I have had excellent results with 400 gr from my 416
Rem."
If you test these Dr Ray please get up nice and close to the target animal so that short range performance is gauged.
Please recover the bullets and estimate the penetration.
