I've not 2 ventures, a 270 and a 308. The 270 likes factory rem 130gr stuff, shooting it into about 1" at 100 yds. My handloads for the 270 are regularily getting 0.5-0.6" groups with 130 gr sierra SBTs. Trigger is pretty nice, with some creep but it breaks good.
On the 308, haven't really had it long, so not much experience yet. I did find a load with 150 Nos BT and 44.5 varget that it likes. A five shot group into a 0.6" group. Still working with this rifle, as it has only about 20 rounds down the tube. Will probably hunt with the 150 BT load this season.
Overall, I really like the Ventures, but the stocks are taking me a little while to get used to, mainly the pistol grip. I think they are the best "out-of-the-box" gun out there. Reasonably priced and now with a $50 rebate. No I don't work for them, but wished I did.
Best of luck,
