40MM Judgement Day

This new round is a 40MM 5 barrel cannon round that can shoot 5 .410 payload wads. As pictured each lead ball is 5/16 in diameter (a recommended payload). This round holds up to 20+ grains of bullseye (XD Pro Base) smokeless powder and uses a 2&1/2 large pistol primer, federal primers are my favorite and works well for weak firing pin springs. This is an easy reloadable round. You press in a large pistol primer, turn it over, add up to 20 grains of powder for flechettes. Use 15 grains for buckshot. You dump the powder in the stainless steel powder cup and put a copper burst disk in. Then screw the hex vent plug and tighten it with a 15mm wrench. Press your 5 .410 brushwads (or any preferable .410 wad) into each barrel as far as they will go. Put your flechettes, buckshots or my favorite is .3125 caliber lead round ball that you can order from any muzzle loading supply company. Then add corkwads or cardboard, one for each chamber to retain payload.

XD Pro Base

The XD Pro Base use small pistol primer that is pressed in with a small tool. It is important to use a perfectly flat ended tool when pressing or tapping in the pistol primer. This base uses the XD pro burst discs.

ACP Base

The ACP Base is versatile and allows users to choose between burst discs or crimped brass blanks. For example, you can use our .45 ACP burst discs (sold separately). This base is also compatible with .45 ACP crimped brass blanks. The crimped brass blanks eliminate the need for copper burst discs. These blanks are available through The Perfect Shot LLC. (

Shell length is 4.0 inches.

Manufactured from high quality aluminum and then hard coat anodized. This casing will also take our 45 ACP powered base.

This is an awesome addition to your 40MM munitions.
