If there's something better than the O'Connor load of 62 gr and a long drop tube, I haven't seen it.
I'm a 55.0 grs of IMR-4350 kinda guy!!

A while back I stopped worrying about the last bit of velocity, and I also lost my taste for compressed loads. So these days when I put together some 270's they're most likely going to be about 55 grains of a 4350 class powder and a 130 grain bullet.
I should say that was only a comment about my present mindset, nothing against the article at all.
