Owner of Buffalo Bore Tim Sundles on Buffalo Bore Heavy 450 Marlin Ammunition:
We always use factory stock firearms to determine our published velocities, so you get true, actual field velocities with our ammo -- not exaggerated long laboratory test barrel velocities.
Item 22C (500gr. FMJ-FN Barnes Buster Penetrator)
You'll note that these 450 Marlin loads are generating slightly lower velocities than their 45-70 counterparts. This is because the 450 Marlin brass (as made by Hornady) has a heavier web and as such the powder capacity was lessened, so the amount of propellant we can fit into the case is slightly less than with Starline 45-70 brass.
