no 5.7 is not the best. Personally, I cant get anything higher than a 4.7 to shoot straight (but lordy those low numbers shoot tight). I just have a 5.7 SA (now that's rare) and want a set to make. JJBduke has a consecutive pair of SA 5.7. I have not shot the 5.6 mil HRA/LMR yet.
The neat ones are the early HRA where they stamped a backward 3 because they didn't have a "&" yet.
