What are the pros and cons of stepped gas check shanks with regard to .35 caliber bullet designs? Is the stepped shank less likely to retain a crimp-on type .35 caliber gas check in flight than a straight shank would?]
The shank length includes the bevel.
Upon firing, the shank obturates (unless you are shooting a wimpy load) so there will be no difference between the different types of check shanks after obturation.
I've never experienced a problem with gas checks coming off in flight.
That's calculated by the CNC software to produce the specified groove angle consistent with the groove depth of the particular bullet. Assuming a 45 degree groove angle, the length of the bevel should be equal to depth of the groove. In your case, (0.361" - 0.327") / 2 = 0.017". However, it is not a controlled dimension.LBD wrote: how long the bevel is just ahead of a .3425" diameter straight shank... is it < .010" (I'm referring to a bullet that has an As-Cast diameter of .361")?
I was gonna say, if your gas checks do come off in flight, and if you're shooting over a chronograph as I usually do, then the errant gas checks will occasionally ding the chrongraph.Wanna see pictures of my dented chronograph?
