No .17 Rem Fireball factory load we have sourced carries 1,500 ft·lb for moose past the muzzle. Here is why, load by load.
| Load | gr | Max ethical yd | MV fps | 500 yd ft·lb | Shoulder shot |
|---|---|---|---|---|---|
| Nosler 20 gr Varmageddon FB Tipped | 20 | wrong bullet | 4,000 | 101 | behind the shoulder only |
| Remington Premier AccuTip-V 20 gr | 20 | wrong bullet | 4,000 | 103 | behind the shoulder only |
At least 1,500 ft·lb at impact, ideally nearer 2,000, with a bullet that stays together. Legal: CO: 1,000 ft·lb at 100 yd, ≥ 85 gr. Floor used: 1,500 ft·lb at impact plus the bullet's published expansion velocity. Orange = a target or varmint bullet (construction, not energy); red = never carries the energy.
