Read EGW Guns Reviews

Our Dies are maufactured by Lee Precision.If a die is available online to purchase, it is in stock. Due to high demand the inventory will be fluctuating constantly.Extra decapping pins available here.A must for the serious reloader: EGW offers custom designed, carbide sizing dies that are 0.003" smaller in diameter than typical dies. Not only is it smaller in diameter, the bottom corner is radiused which sizes the case further down. This helps prevent feed failures from cases that bulged near the base during reloading- which is typical of brass fired in Glocks and other loose chambered guns. The dies are made out of carbide.No lubrication needed. Because the carbide is so hard, no lubrication is required on the case. You will find the die will actually burnish the case and improve its appearance. The die will last a lifetime! Screw the full length sizer in until it touches the shellholder and tighten the lock ring finger tight. The decapper is retained by a collet. Should it be overstressed by an obstruction, it simply slides up without damage. To reset, loosen the decapper flush with clamp end and retighten. Considerable torque may be necessary. A 1/2" and 3/4" wrench are required. Undersized Reloading Dies will work with a Dillon Press if they are 550, 650, or 1050. They will not work if they are squared.

The die worked well. Ammo from range brass failed to pass case checker about 5% of the time. Undersized die cured that.

Works great on those bulged Glock cases.

I was having trouble with range brass fired from Glocks. This is the answer!

I use the "U" sizing die to get range pickup, Sig .357 brass to fit like factory-loaded brass in my EGW .357 Sig case gauge. I have not taken them to the range yet but my dummy rounds are loading and ejecting from my SIg P226 like a champ! I Liked it so much I ordered a 9mm "U" die and I'm waiting for my checking account to catch up so I can order the .45ACP "U" die for difficult, aka "Glocked", cases. I have two Glocks but given they are .40 S&W, I swapped out the barrels for KKM barrels before I ever shot them.

Started with 10mm die along with Lyman crimp die to eliminate 'Glock Buldge' found in used range brass from various makers. Worked so well I bought .40 S&W die to use in 4-hole turrets of Lee Turret press. Now my reloaded cartridges function well without jams in match-grade barrels & supressors.

Die can only be adjusted down to shellholder there for the last 1/8 inch of the brass does NOT get sized

Works great to resize range brass, especially brass that was shot in a Glock. I have a gun with a tight chamber and this does helps make sure rounds fit.

Problem: Could not resize 2000 rounds of once fired nickel cartridges using a standard Lee die. Most cartridges had a "bulge" near the base where the standard resizing die could not reach. Problem solved: I ordered and used the Lee U die (undersized). In so doing, the resulting ammunition chambered and fired without issue in my Beretta PX 4 Storm.
