I shot groups with them in the Omega and the Triumph, no problem getting decent groups average a bit over an inch but they shot quit low off the Omega and about 4 inches low on the Triumph. I jumped the charge to 110 gr BH209 which brought them close to the sights and the groups opened a little, They shot under an inch with 90 gr BH but would have to change the sights about 14 inches from where the sabot loads impact.
