Its called a "bullet comparitor"I am trying to order an OGIVE gauge. Are they universal for 0.308 calibers or do you need to get separate ones for 30-06 and 300 WM? Any advise what models are good. I need one to fit the caliper shown in the pictures.
They are all the same .308 dia. Bullets so yes the same gauge will work for all of them. I already linked the Hornady one in a previous post should be within the past few pages. But i will try and find it again here.
I use the Hornady insert holder. (Its the same holder for measuring headspace AND bullet seating depth (for ogive)
There is two sets. One set is for headspace. One is for bullet seating..
I got the long body holder so i can measure anything inside without the bullet tip bottoming out inside. (So no matter how long the bullet it will git over it.)
So i just ordered the headspace set. And then i ordered the specific (steel) inserts for .22 and 6.5
I also have the Brownells hex nut style ones. I WOULD NOT recommend those. They are tapered cones. And more confusing and inconsistent BUT they are cheap. So they are tempting. They are a great idea executed poorly.
