So I have a 22 creed and Im in a feedback loop on what I should shoot. I had initially wanted an 85 rdf but Im thinking about hornadys now too since there is just more data out there for hornady in the creed that I can find in the depot and elsewhere for comparison.
I have a 26" 7 twist barrel
I have alpha small primer brass.
I have a new jug of H4350 for powder, dont really want to hunt down slower powders.
So numbers Im seeing for top end speeds, (correct me if your info disagrees). I see 75s reported to be 34-3500 fps, Im seeing 80s at 3300 fps, Im seeing 88s at 3100 fps.
With my 7 twist ALL of these are really friggin spinning.
A 75 at 3400=350k rpm
An 80 at 3300=340k rpm
An 88 at 3100=320k rpm
I know I see lots of reports about the 88 spinning apart at these speeds, some claim its because the same jacket is used in all thee of these bullets so to hold the extra material in the heavier bullets the jacket get stretched thinner.
If so, could it be in a margin where a 75 at 350k rpms might be able to hold together better than the 88 at 320k? And if that is the case do we think that the 80 might be on one side or the other? I dont see much about the 80 really though, dont know why.
My other thought, is that since I have h4350, which is faster than the rl26 that many seem to like, that a lighter 75-80 gr bullet might be a better match with that burn rate period?
