I am trying to work up a load for a Barnes 62gr TSX in .223 rem. I used the load data from Barnes website but was unable to get any sort of groupings. I used the bottom load, which was around 2800 fps. I could get all three on paper at 100 yds but they were all over the place, I mean about a 9" spread. I tried this with all 20 rounds that I loaded. No consistency in three different rifles. I have tried other factory loads in the weight class of 75 grns and had the same problem. I have loaded Varmint Grenades in 36 grns and can pull 1 inch groups out of the same gun (Bushmaster), listed at 3514 fps. Sierra 55 grns FMJ are about 1 inch groups as well (all 3 rifles). I have loaded the TSX in .308, .270 and .300 WSM, all with 1 inch groups and absolutely love these bullets. They did nice work on two deer this year.
What I'm asking is, do I need to bring the velocity up with the heavier bullets to improve the accuracy? It seems the faster the .223 goes, the more accurate it becomes, obviously to a point, but that is what it seems. All of the loads that seem to get over the 3000 fps do well.
Any thoughts and ideas would be appreciated.
