Which cartridge part number holds 4.5mm BBs in the Crosman SNR357?

The dedicated factory cartridge for steel BBs is Crosman part number CRVLBUL6P. Crosman manufactures this two-tone shell specifically as a 4.5mm BB revolver casing in packs of six. It is built to hold a single 4.5mm steel BB firmly in the tip, preventing loose rounds from rolling forward into the cylinder gap and stalling your revolver.

Can Crosman SNR357 pellet cartridges also shoot steel BBs?

No, you should not load steel BBs into pellet casings. Crosman produces part number CRVLPEL6P as an all-gold casing engineered strictly for .177-caliber pellets. Because pellet casings do not share the internal retention design of CRVLBUL6P BB cartridges, steel BBs can slide out of position and bind the cylinder rotation against the forcing cone.

Can you use 6mm airsoft cartridges in the Crosman SNR357?

No, 6mm airsoft shells will not fit or fire in the Crosman SNR357. Cartridges such as Black Ops model B1047 are sized specifically for 6mm plastic BBs and airsoft revolvers. The SNR357 is machined exclusively for .177-caliber (4.5mm) ammunition, meaning 6mm airsoft casings will fail to seat inside the chambers and will lock up the action.

Do Bear River Barra 357 cartridges fit standard BBs?

Yes, Bear River Barra model B1188 cartridges are listed for both .177-caliber pellets and steel BBs. These golden shells measure 2.5 inches in length and are designed for .357-style airgun cylinders. Bear River also offers model B1707 bronze cartridges, which hold one .177 BB per casing. Before shooting them in an SNR357, verify that the 2.5-inch shell length and rim thickness sit completely flush against your cylinder face.

What BB ammunition works best with Crosman SNR357 BB cartridges?

Standard 4.5mm steel rounds, such as Crosman Copperhead copper-coated BBs (part number 0737), offer the correct fit for these shells. These 4.5mm BBs match the internal diameter of CRVLBUL6P cartridges and feed smoothly through 4.5mm-caliber BB air pistols. If you run a CO2 BB gun for realistic training and plinking, uniform BB dimensions prevent loose seating and keep your cylinder cycling without friction.

Do ASG Dan Wesson BB capsules work in the Crosman SNR357?

ASG model 16783 capsules are made specifically for Dan Wesson .177-caliber BB revolvers and hold one 4.5mm BB per brown shell. While they chamber standard 4.5mm airgun BBs, ASG specifies them for Dan Wesson airguns only. Because shell tolerances and rim thicknesses vary across revolver brands, check your SNR357 cylinder depth and ejector star fit before attempting to shoot third-party Dan Wesson shells.
