Check the listing for details. RCBS Chargemaster 1500 Charge master combo lot MEDIUM Overthrow Insert air dam. Condition: New other (see details). Listed at 9.00 USD. RCBS Chargemaster 1500 Charge master Lite MEDIUM Reducing Insert air dam shield combo. This is a 3d printed item to be inserted into the spout of the rcbs chargemaster. I have been using this for several months and works great when you want the correct charge the first time. Highly accurate for when u want the exact amount of powder. Prevents large clumps coming out at the wrong time that creates over charges. This auction is for the insert located on the righ in the last picture. If your looking for a small hole insert look at my other auction. Also included is a rcbs air dam shield to prevent air from hitting the scale. This help get a perfect charge every time. Check my other auctions for more 3d printed reloading pieces. THIS AUCTION IS FOR ONE INSERT AND A AIR DAM SHIELD and NOTHING ELSE. MIGHT HAVE TO ADJUST TO MAKE A TIGHTER FIT SO IT DOES NOT FALL OUT WHILE SPINNING. I SUGGEST PLACING TAPE AROUND THE SHAFT UNTIL FIT IS TIGHT. DO NOT HAVE TAPE STICK OUT PAST END OF SHAFT OTHERWISE POWDER WILL STICK TO THE TAPE.
