Description
The PowerBelt ELR is the long-range flagship of CVA's bullet family, and this .50 caliber 250-grain version is built for hunters who want to reach out past where a typical muzzleloader projectile runs out of steam. The Aerotip nose feeds a slick, aggressively tapered shape that carries a .312 ballistic coefficient, which is impressive for a full-bore muzzleloader bullet and translates to a flatter trajectory and more energy left downrange when it counts.
What Makes the .50 Cal ELR Reach Out
CVA developed the ELR alongside the Paramount rifle, but it will perform in any fast-twist .50 caliber muzzleloader that can safely run magnum or super-magnum powder charges. In factory testing with the Paramount using a max Blackhorn 209 charge, the .50 caliber ELR clocked right around 2380 fps at the muzzle. That velocity, combined with the high BC, is what keeps this bullet honest at extended distances where most conical and sabot loads have already dropped off.
Loading and Fouling With the PowerBelt ELR
The bullets are sized about .001 inch under bore diameter, so they seat smoothly without a fight. The polycarbonate tip protects the nose profile and helps drive proper expansion on game, while the fluted, large-diameter gas check gives you a tight seal and consistent shot-to-shot behavior. They run clean too, leaving very little plastic residue and letting you fire up to about eight shots between recommended barrel swabs. One tip from the field: the extended Aerotip loads best with CVA's dedicated ELR loading tip, which has a deeper recess to protect the nose during seating.
Built for Serious Game at Distance
This is a projectile aimed at deer, antelope, and elk-sized animals where a flat trajectory and clean expansion matter. The smaller hollow-point cavity is tuned for controlled expansion with minimal fragmentation, so you get penetration and a reliable wound channel rather than a bullet that comes apart on impact. If you've been chasing a muzzleloader load that behaves more like a modern centerfire at range, the ELR is about as close as it gets.

Frequently Asked Questions
Do the PowerBelt ELR .50 cal bullets only work in the CVA Paramount?
No. CVA designed the ELR around the Paramount, but it will run in any fast-twist .50 caliber muzzleloader that can safely handle magnum or super-magnum powder charges. You'll get the best out of them with the higher powder volumes they were built for, so they're best suited to modern inline rifles rather than traditional side-locks.
What kind of range and velocity can I expect from the .50 cal 250-grain ELR?
In CVA's testing with the Paramount and a max Blackhorn 209 charge, the .50 caliber ELR ran around 2380 fps at the muzzle. Paired with its .312 ballistic coefficient, that gives you a noticeably flatter trajectory than most muzzleloader bullets, which is exactly why it carries the long-range name.
Do I need a special loading tip for the ELR Aerotip bullets?
It's strongly recommended. The extended Aerotip needs a loading tip with a deeper recess so the nose isn't crushed during seating and the bullet stays aligned. CVA's Paramount ELR loading tip (AC1722) is made for exactly this and is milled from brass so it won't scratch your bore.
How often do I need to swab the barrel when shooting the PowerBelt ELR?
These full-caliber bullets leave very little plastic residue, so you can typically shoot up to about eight rounds before a barrel swab is recommended. That makes range sessions and load development a lot less of a chore compared to bullets that need cleaning after every shot.
