If you shoot "Blackhorn 209" you will never shoot anything else in your Optima Pistol. With the other powders I couldn't get much accuracy from mine without cleaning after every shot...but then the BH209 was tried and it gave me 3" groups at 100yards. I think it will do better, but the 3" is plenty good for a handgun.

I did not buy the extra BH209 breech plug and I have never had igniton problems while using regular 209 primers. CVA offers a special BH209 plug...but it is not needed.
