The goal was simple: figure out which big-bore subsonic bullets actually do their job, and why barrel length and twist rate change everything. EagleRun23 opens the video still in awe the morning after. He was invited to meet Mr. Bill Wilson of Wilson Combat himself — a man who acquired Lehigh Defense several years back and now builds some of the wildest big-bore projectiles in the industry. The agenda, in EagleRun23's own words, was \"essentially trying to convince Bill Wilson that subsonics are cool.\" Wilson is a velocity guy. He even created the 300 Hammer, a cartridge he runs supersonic. But the projectiles coming out of Lehigh Defense — and Bill's genius method for testing them — are exactly what a subsonic .338 shooter needs to understand before spending money on a build. Key Takeaways The projectiles were tested in a 48-inch-deep, 16x16 water tank with a 1-inch closed-cell foam bladder at 100 yards. EagleRun23 recommends a 1-in-5 twist for 99% of 8.6 Blackout / .338 ARC shooters — fewer accuracy problems and a wider bullet selection. The 300-grain Lehigh/Howorks fracturing load was described as \"the most accurate by far\" — if it won't tig…
