I hate sideways-flying bullets. Not even 90 grains (vol) or under?
We all do... In the DISC Extreme/Elite series the twist rate is to slow to stabilize the length of the 40x200 in some rifles especially when loaded with softer powder loads. In the faster twist rifles it does not appear to be a problem. Lehigh is aware of this and will/does offer a 185 grain bullet to compensate for that factor.
I understand the desired testing bullet speeds are up around 2K. But how would the XP Lehigh bullet do at around 1.5K? Not all of use are hunting 200-300 yards. I generally work inside 150.
I understand what you are indicating and with the XP of appropriate length for your twist that is not a problem.
In my particular case the older 40x200 CF shoots great down to 100 grains - never tried any less than that. The 40x200 is really a soft recoiling bullet. Sorta like shooting a 22 Mag or 17HMR - no its gotta be bigger than that I could easily relate it to a my 222 or 22-250.
Also, when you speak of 40-cal destabilization, are you talking 'flight', or you talking going sideways when entering one of those testing gel-blocks?
Flight thru the air and hitting a paper target - so tumbling.
But again if you have a slow twist just get the 185's
I am hoping to find out a lot more this afternoon at the farm.
