Yeah you have to learn how to squeeze your bag. It takes a gentle touch...
I hope to have my 20" 243 LBC barrel ready to test fire in a few weeks, probably during the holidays. I'm interested to try the same loads in it and compare velocity to my 24". They are both BHW barrels and both chambered by BHW, I just have to profile and finish the 20". My 24" was a complete barrel from them (~$350 IIRC, and worth it IMO.) I'll report back here with some numbers.
