Bob advised that I should have them made with a rebated boat-tail and when I asked him why?? that design he told me that everything he had fired through the spark graph range with a rebated boat-tail had shown a minimum of a 5% increase in performance over the standard boat-tail configuration! That doesn't sound like much but in the case of having to make a 'shoot off'....a 5% increase in X count wins the pot!!
Sharpsman, I've seen you recount this story several times on various sites. Can you help me understand this statement. What metric was McCoy referring to in that 5% increase in performance?
Do you have any samples of your 176 Delta's that you can share a photo of? I'm curious what they look like.
On a different note, I am pretty sure that your 176's did not drive Sierra to produce their 175's. It was actually PWS wanting an analog to the 173 FMJ for what ultimately became M118LR.
