I have been using the Woodleigh bullets in a number of calibers for over 20 years.
They are an awesome bonded lead core bullet that will work well on small, medium and large deer size animal.
I use the 180gr PP designed for the .300WM in my .300 Jarrett (at 3150fps) on Fallow deer 60-80kg (130-175lbs) and Red deer 180-200kg (400-440 lbs) a number of times with great success.
On side on vital area shots they will often pass straight through between up close out to 200 yds or more.
Angled shots sometimes do not exit and present as perfectly mushroomed bullets often found just under the skin on the far side.
My observations are that they are softer up front than Swift A-frames and Nosler Accubonds in the same caliber and weight. Meaning they will have on average a larger mushroom diameter (bigger frontal area) than the later two bullets mentioned. But their retained weight is still often over 80%.
I have never seen or heard of one failing among my group of hunting friends. Over here in Australia they are the most affordable premium bullet in our market.
