There was some talk in the ammunition section about different Barnes TSX loads in the 5.56mm. About two years ago I developed some loads for the 70gr and 62gr TSX and for the Nosler 77gr OTM. All brass used was Lake City and primers were CCI#41 and a Lee Factory Crimp was used. For the TSX's I seated the bullet to the first band closest to the tip of the bullet, I didn't write the COAL down. Start a grain lower and work up. These loads are for 5.56 chambers only, do not use for .223.

1. 62gr TSX - 23.5gr H322
A. LWRC 10.3" M6A1 1x7 twist - Average - 2646
B. Colt 6920 16" 1x7 twist - Average - 2862

2. 62gr TSX - 25.1gr H4895
A. LWRC 10.3" M6A1 1x7 twist - Average - 2564
B. Colt 6920 16" 1x7 twist - Average - 2808

3. 70gr TSX - 24.3gr H4895
A. LWRC 10.3" M6A1 1x7 twist - Average - 2499
B. Colt 6920 16" 1x7 twist - Average - 2783

4. Nosler 77gr OTM W/cannelure rolled by hand with Corbin tool - 23.6gr H4895 COAL 2.260"
A. LWRC M6A1 10.3" 1x7 twist - Average - 2399
B. Colt 6920 16" 1x7 twist - Average - 2633

The 70 gr TSX and the 77gr OTM's need a 1x7 twist barrel to properly stabilize. Some 1x9's work, but I had a 1x9 that failed to stabilize the 70gr TSX and the bullets were impacting the target sideways at only 10 yards. The 70gr TSX is very long bullet. I guess I should have tried some H322 with the 70's. Maybe this summer. I didn't shoot any of these at 100 yards, only 50, and they were around 1/2 inch.
