115 DTAC Nose Ring G7 BC

[radical1911]

Anyone have a trued G7 BC for 115 DTAC bullets with the nose ring.

I know the standard dtacs true up around .315, I have heard that the nose rings are a little less

Thanks

I got somewhere around a .296 @ 2900fps using the labradar tracks. I think using 4dof drops it trued a little higher but I can't find it in my notes and I've moved on from DTACs.

They were ran through an AB lab by a guy on rokslide, believe they were avg of 293g7 to transonic. They'll likely true around 0.300 800y and in.

In my experience the bc on dtacs is not consistent lot to lot. Also, the nosering cut is not consistent lot to lot. I have used them since the rbt version came out in 243 Ackley. Many barrels and many thousands of bullets. I buy enough to toast the barrel and true. Sometimes the bc is better than advertised, sometimes worse.
