I have 2 of the quarter bore 06's and I absolutely adore them. With that being said, if I had to start over now, I would go 243 Win with 85 gr TSX @ 3200fps and never look back. I've seen over fifty deer and speed goats meet their demise with this setup. I am impressed. You are the one who has to pull the trigger so to speak. Pick the one that fits you the best and have a long and happy hunting career.

Have fun, Tom
