Maybe, maybe not. Sometimes I do not let the barrel cool properly when its hot out.

Time will tell with the Omega. The 50yd groups were shot with 105gr of BH209 so I will see how it does at 100yds with that load. Actually I just threw 25 charges with 72gr of BH209 threw my new Chargemaster 1500 tonight. 72gr by weight is just a tad more then my volume measurer throws set at 105.
GM54-120,
25 charges thrown, zero errors. This Chargemaster is sweet!
