OFFICIAL .308 PRECISION LOAD RECIPE THREAD (Page 4 of 4)
|
I redeveloped a load for my XM-3 knockoff, since R15 is stupid expensive. I had varget on my shelf, so varget it was. I pasted the link to this thread into Grok and asked Grok to retrieve all recipes with Varget, then asked for Varget and 175 gr bullet. Here was Grok's response: Here are all the load recipes from the provided AR15.com thread that specifically combine Varget powder with the 175 grain Sierra MatchKing (175 SMK, 175gr SMK, etc.). I've listed only the matching ones with full extracted details (powder charge, components, velocity, rifle info, notes, and warnings where present). These are user-reported loads—always start 10% below listed charges, work up slowly in your own rifle while monitoring for pressure signs, and cross-reference with current published data. Post #6 (LRShooter): Powder: Varget, 44.0 grains Bullet: 175 SMK Primer: CCI BR Brass: BHA brass OAL: 2.810" Velocity: ~2630 fps Rifle/Barrel: Savage 10 with 1/10 twist 24" barrel (bolt gun; also tested in new 26" Shilen barrel) Notes: Part of a set of tested loads; accurate in the original barrel setup. Post #7: Powder: Varget, 43.7 grains Bullet: 175 grain SMK Primer: WLR (Winchester Large Rifle) Brass: Winchester brass OAL: 2.800" Velocity: Right around 2600 fps Rifle/Barrel: 24" 10-twist Savage (bolt gun) Notes: Straightforward accurate load reported. Post #39 (WUSSCVR): Powder: Varget, 43.1 grains Bullet: 175gr SMKs Primer: CCI Brass: Hornady Match brass OAL: Not specified Velocity: Not specified Rifle/Barrel: FN PBR XP (bolt gun) Notes: Proven great for accuracy; no pressure signs observed. Described as "by no means a hot load." Warnings: Start 10% low and work up just for safety. No other loads in the thread document strictly match both Varget + 175 SMK (many use Varget with 168 SMK, 155 SMK, etc., or 175-grain bullets from other makers like Hornady/Berger). General references to Varget (e.g., 44gr as a bolt-gun starting point) appear, but these are the only specific combinations with the 175 SMK bullet. If you're loading for a particular rifle (bolt vs. semi-auto, barrel length/twist), these tend toward bolt guns with 24" barrels and velocities in the 2600 fps range. Let me know if you need comparisons to non-Varget 175 SMK loads from the same thread or help narrowing by rifle type! I ended up with this load 175 TMK, Hornady brass, Fed Match primers, 43.2 gr Varget, 2695 fps, 7.6 SD for 10 rds. I think this load is ok  Attached File Attached File Attached File ETA: overlayed both groups on top of each other Attached File |
