My similar Borden 280ai build should be ready in a month. I am pre loading some 150 TTSX with N165, 140 and 150 BT's with IMR 4831 and N165, will also try some RL 19 and 22. My gun will have a Hart#3 24" and a Rem Sporter McMillan Edge fill. Guessing will come in a tic under 7lbs. Will prob top with a 3-15x44 Swarovski or a 3.5-12 x 52 Kahles. I think the Kahles is a better scope but is slightly heavier.
