June 16, 2022 Keith Glasscock, a top competitive shooter, has been second at multiple F-Class National Championships (F-Open), and is now an outstanding competitor. Keith is also a skilled coach for wind and runs the Winning in the Wind YouTube Channel. Along with his interest in mid-range and long-range F-Class competition, Keith also enjoys game hunting and varmint adventures.Developing accurate hand-loaded ammo for hunting and varmint rifle can benefit from some procedures that may be a bit different than loading for a match rifle. You want to be efficient and use the right types of bullets and brass for the hunts. Keith shows in two videos how he created accurate loaded for a Remington 700 bolt action varmint rifle chambered with.223 Remington. Keith begins by sizing the brass to its full length. Next, he tried powder charge weights and came up with a promising load consisting of 24.7 grains Alliant AR Comp with Hornady50gr A-Max bullets. Next, Keith tried different seating depths (see 5:30-6.100). He found that accuracy improved when he varied OAL length in increments of.005. Keith came up with 2.270? With a 3-shot group of twos! This video shows how important it is to test your bullet choice at different seating depths. Keith shoots this rig with a prone-off bipod, similar to what he does in the Varmint Fields. Keith explains the key points to consider when optimizing a.223 Rem cartridge for a varmint rifle. Velocity readings can be taken using a LabRadar unit. Load Development for the.308 Win Hunting rifleIn a second video Keith shows how to load develop a.308 Winchester hunting rifle. Keith uses a large X type sandbag as a support. He was again shooting a Remington 700 bolt action rifle. This time he used Barnes TSX solid copper bullets. Federal 210m primers and AR Comp powder. Keith commented that the Barnes bullets were outstanding — he said they were “match-quality in terms of precision.” Keith was able to achieve very small three-shot groups using AR Comp and TSX projectiles. Keith did notice that the point-of-impact changed significantly with increasing charge weights (see 6:20-7.10). This is important to pay attention to during load development as you may need adjust your zero after testing. Similar posts:
