New For 2018! We now have extra tall copper .303 gas checks
These are our unique .303 caliber copper gas checks made using .017 thick gilding brass, also known as 210 copper. Made for a normal .284 shank bullet, these are extra deep for long shanks. The .303 gas checks are about .010 taller than our regular .30's.
The checks are sold in resealable clear plastic bags. Shipping is based on each item's weight. USPS postage rates are calculated in the shopping cart. USPS flat rate boxes and First Class mail are used to reduce shipping cost. Most orders ship in one business day Monday - Friday.
Sold in 3 quantities: 250 for $8.25, 500 for $14.50 and 1000 are only $25.00.
