yeah Dave we all used to use 1:8 twist barrels but then Berger adjusted their recommended twist rate for the 105gr hybrids to a 1:7.5 twist recommended, so i and other use a 1:7.5 twist if we are going to use hybrids just to make sure even though they still shoot great in a 1:8.. just covering my ass

as for tuner some swear by them some don't, i'm only really trying one out for my own mind as i've never had one or used it, EC tuner say to fit in a certain spot and carry out load test as per normal, powder then seating and once that is done start to adjust tuner ..but time will tell
