I don't know one person i can think of who didn't get excellent accuracy out of the .250 TEZ in a T/c triumph/ omega.start with 90 grs 3or5 shot group swab with windex or 50/50 windex alcohol mix mix.if thats no acceptable try 95 grs all the way up to 110 in 5 gr incruments. the TEZ's in my triumph load with what i feel is perfect pressure. not to hard and not to easy. the .250 gold dot/deep curls with a crushed rib sabot load about the same and are just as accurate.most of the guys here in certain parts of california have to shoot copper, due to the condor/big vulture lol and they shoot omegas and triumphs and the TEZ is the go to bullet and deadly accurate. i don't live in the portion of california that requires me to use copper.and most of the time 110 grs Bh 209 gives optimal performnce.. patience helps until you find the right combo.
