I have the LTR wich is pretty close to the exact same thing and have shot 69-40's. Surprisingly enough it shot everything well.
I thought maybe the 1-9 would be a bit fast for the 40's but I shot my best groups with 40gr. Blitzkings and a little over 27grains of Benchmark. Shot some sage rats with that load the other day and all I can say is POOF!
For me the closer range, 200yds or less, stuff I really like the 40's. They flat blow stuff up. Out past 200 the 52-60 bullets would be a better choice. The 69's shoot great but I only shoot steel targets and stuff with those. They aren't much fun on critters.
