Ultramax Rifle Ammunition Features The Ultramax Subsonic .45-70 Government load is engineered around a 550-grain Hi-Tek coated hard cast bullet a heavy wide flat nose projectile designed to deliver deep straight-line penetration on game or through suppressor baffles alike. Running at subsonic velocity eliminates the sonic crack a supersonic round produces making this load a natural pairing for suppressed lever guns and single-shot rifles chambered in .45-70. Precision loading behind each bullet ensures reliable ignition and a stable trajectory so shooters can count on repeatable terminal performance shot after shot. The brass casing supports dependable extraction and is a candidate for handloaders looking to reload their own subsonic .45-70 ammunition. Each box holds 20 rounds giving shooters a practical supply for range sessions or a hunt without the bulk of a larger case quantity. The Hi-Tek coating also reduces barrel fouling compared to traditional lead bullets keeping bores cleaner across extended shooting sessions. This combination of controlled velocity and a heavy hard cast bullet makes the load well suited to close-range hunting or defensive use where a suppressor is part of the setup.
