Looking to put together another AR and have tried to extensively research these two calibers in comparison and I'm curious of anyone's opinion that has either/both. Basically what I'd like to do is potentially run a 55 grains Nosler BT in the 3500 speed range (if possible) with a 20" barrel..preferably NOT 22". It seems pretty much doable with the 6DTI but didn't know if any of you had a 6x45 with that length of barrel and what kind of top speeds combined with accuracy you've experienced with the 55's. I'd rather run the 6x45 due to brass availability and cost but am considering the 6mmDTI from Dtech because of the probability of fitting those desired requirements of a 20" light contoured barrel that will get me either 3500 or pretty close to it. If you have specifics on 1:10 vs 1:12 twist that'd help as well.
Thanks,
