Big 410 Slug Ballistics from HBBS
The HBBS 410 Rifled barrels were developed for deer hunting and were first promoted for the hand loader who could optimize their loads for extreme accuracy and power. While extreme accuracy and power are possible and available in the HBBS Rifled 410 bore, it does not require extreme chamber pressure to achieve them! A fact difficult for many people to believe. Prototype loads for the HBBS 410 Heavy factory load and the HBBS 410 Youth load have been laboratory tested and have been found to be within SAAMI specs for 410 bore chamber pressure. It is now a scientifically proven fact, believe it or not! These same tests show very consistent velocities from round to round, another contributing factor to the extreme accuracy.
Hoening Big Bore Slug developed and tested many loads including those shown below to provide users of our barrels a starting load to work with. The loads show the versatility of the HBBS 410 barrels and the ammunition loading methods. They are available in brochure form with purchase of barrel.
