Frequently Asked Questions

What velocity does Fort Scott list for this load? Fort Scott lists 3870 fps from a 24-inch test barrel with a 1:10 twist.

Does this load contain lead? No. Fort Scott lists the bullet as non-lead solid copper.

Does Fort Scott give any prep or handling guidance for this ammunition? Fort Scott recommends cleaning your barrel thoroughly before shooting solid copper or brass if you have been shooting other ammunition, since a clean barrel improves accuracy and performance with solid monolithic ammunition. It also notes that repeatedly cycling an unfired cartridge can cause the projectile crimp to fail and the bullet to loosen, more often with larger monolithic projectiles. For AR10 platforms that are not mil-spec, Fort Scott recommends polishing the feed ramp before use and checking the headspace of your firearm.
