Thompson Center Arms, LLC 9053R U-View Flex Loader 50Cal Red/Clear Plastic

The Thompson Center U-View Flex Loader is a handy powder-and-projectile carrier purpose-built for 50-caliber muzzleloaders. If you're serious about black powder hunting or range work, this loader solves one of the field's persistent annoyances: keeping track of your charge weights and staying organized between shots. The see-through design lets you monitor your powder supply at a glance—no more fumbling or guessing when you're deep in the field. Load up to three complete shots' worth of powder, projectiles, and primers, clip it to your pack, and you're ready to work.

Built from Thompson Center's Bio-Flex silicone material, the U-View stays pliable even when the temperature drops, so it won't crack or stiffen in late-season cold. It's flexible enough to handle rough use without shattering, yet rugged enough to stand up to the typical field abuse that comes with muzzleloading. The design accepts magnum charges of up to 3 Pyrodex pellets, so whether you're running standard or hot loads, the loader can handle your setup.

Organization matters when every shot counts. The carrier holds projectiles and powder charges in dedicated tubes—no mixing, no confusion. A dedicated slot stores four 209 shot shell primers, and a lanyard hole lets you tether the whole rig to your shooting bag or belt. One compact piece of gear eliminates the need to juggle multiple containers between shots, freeing your hands and your mind to focus on accuracy and fieldcraft.

Frequently Asked Questions

Will this loader work with my 50-caliber inline rifle?

Yes, the U-View Flex Loader is designed specifically for .50 caliber muzzleloaders, as well as .45 caliber models. It accommodates magnum charges up to 3 Pyrodex pellets, so it'll work with most common 50-caliber hunting loads.

How many shots can I prep with one loader?

Three complete shots. Each of the three loading tubes holds a projectile and a powder charge, so you can load three shots' worth of components before needing to refill.

Does it keep primers with the powder?

Yes. The loader has dedicated storage for four 209 shot shell primers, so your primers, powder, and projectiles all stay together in one organized carrier.

What makes the Bio-Flex material different?

Bio-Flex silicone stays pliable in cold weather, where standard plastics can become brittle and crack. This matters if you hunt late season or in places where temperatures drop significantly.
