Questions about .223 I'm sure you've answered

I tried several loads and brands up to 62gr in my 1/9 without much luck on the heavier rounds. But it groups the 55gr Hornady Spire points extremely well.

My 1/7 likes the HyperClean 75gr and groups very well so I have several on hand. The last time I shot, I tried the 75 grain HyperClean rounds in my 1/9 and I be darned if they didn't group as good or better than the 55gr rounds.

I'm with you, "Go figure". But it's true.

Mine is the same on 62 gr. and 69 gr., but it really likes Hornady Superformance 75 gr BTHPs. All I have shot is factory ammo, but I went through quite a variety until I found a load it liked. I like the performance of that load on hogs and yotes as well.

My Daughters CVA Stalker has a 1:9 twist and shoots Winchester 64 SP into a 1" group easily at 100 Yards

.. ..but for hogs I use the Federal "green tips" in 5.56 but sorry, don't recall the grain?

Green tips are 62 grains

A 1:9" twist will stabilize the 75 grain Hornady BTHP, which has a fragmentation profile like the 77 grain Sierra or Nosler (which won't stabilize in a 1:9" twist). A friend's son has used that load on a whitetail doe with great results.

Don't pay any attention to what bullet weight is supposedly best for a given twist. The twist rate is either sufficient to stabilize that length bullet (weight is used as a proxy for bullet length) or not. Overstabilizing a bullet—i.e. spinning it faster than necessary—only matters to bench rest shooters who don't want their bullets precessing. A bullet precesses when it spins so fast that the spinning bullet rotates around an axis. (Think a toy top.) The bench rest shooters don't like this because it will increase group size a tenth or two.
