In an effort to find the most accurate loading of TAC and LC brass, here are half of my results. The other half I will complete in the coming months. Bullet weight and type in the top left, powder charge of TAC in the top right in .3 gr. increments. Tula SRM primers. 4 shots at each charge. 4x12 Leupold scope. Sand bagged, took about 2 hours to send these 92 rounds down range. Definitely a lot of losers, a couple winners. Ran through a 16" BCM Middy @ 125 yards. Looking for group size, not position. I noticed that some of the lead tipped rounds did not fully chamber on charging the rifle. Fwd assist fixed that. All shots, the bolt fully closed. Bullets fired, Sierra 63 gr. SMP Winchester 64 gr. PP Sierra 65 gr. SBT Hornady 68 gr HPBT-M Bullets I still need to test, Sierra 69 gr. SMK Barnes 69 gr. Match Burner Nosler 69 gr. HPBT-M Speer 70 gr. Soft Point http://home.earthlink.net/~squirreld/63%20gr.%20Semi%20point.jpg http://home.earthlink.net/~squirreld/64gr%20Win.%20PP.jpg http://home.earthlink.net/~squirreld/65gr%20Spitzer%20BT.jpg http://home.earthlink.net/~squirreld/68%20gr.%20Horn.%20HPBT-M.jpg I'm really not crazy about any of these results. 63 gr. SMP was marginal at low and max loads. 64 gr. Win. PP is an all around loser. 65 gr. Sierra SBT looked good at 24.9 gr. of TAC. 68 gr. Hornady looked good at the 2 lower loadings, you can see this pattern open up nicely.
