Hand crafted on single stage presses with each powder charge weighed (not measured by volume) individually to within 1/10 grain for consistency. The Accubond bullet expands quickly for intense knockdown power with excellent weight retention to increase the likelihood of an exit wound and good blood trail. Sold in boxes of 20 rounds. We also offer test load kits in packages of 40 rounds which include 10 rounds of 4 slightly different powder charges to find out what your particular rifle prefers for $109.00. This will give you enough for 3 3-shot groups of each load with allowance for one stringer. Detailed instructions come with these test load kits.
