I had an interesting experience today with the same 22-250 mentioned earlier was testing some 62g varmagedon i wanted to see if i could get a load with cfe223. 2 loads on the upper end of my test had bullet failures out of 10 shots with the 2 groups i had 4 bullets come apart i thought i seen dirt fly when shooting about 40yds in front of me. Sure enough when i walked up to check groups i seen where parts of them hit the ground and missing 4 holes on paper for those groups.
Now im not saying this was my fast twist as it could just be a bad batch of bullets or their construction but none the less interesting i forgot my chronograph but estimated around 3400-3500 on the ones that failed. Disappointing as the groups were getting better the faster i pushed em
Im gonna test them in my 1/9 223 as well see if i have better luck
