Turkey,
I believe all the Mossberg 835 barrels are 1 in 36 twist...
From Cabelas...
"The
Model 500, 835 and 935 Trophy Slugster (TS) Barrels have an integral steel scope base for mounting standard-eye-relief rifle scopes. 1-in-36" rifled twist stabilizes slugs to greatly improve accuracy."
In general this means your gun should do well with the same shells that perform well in other guns with similar twists. Those would include the Savage 210, and Mossberg 695, amongst others.
I can say from experience,(I own a Savage 210, and have shot the Mossberg 695 quite often), as well as speaking to many others that shoot 1 in 35/36 twist guns that the following shells are a great place to start...

There seems to be three or four favorites that will shoot inthese guns. Ideally you get lucky and the one with the best ballistics performance also happens to give your gun the best accuracy.
The top four are:
Winchester Partition gold
Lightfield Hybrid Exp
Remmington Copper Solid
Remmington Core Lokts
In terms of down range performance, they rank from best to worst:
1).Remington Core Lokt Ultra's/ Winchester Partitions
2).Remington Copper solids
3).Lightfields Exp
To give an idea of how far behind the Core Lokts/Partions the Lightfields are think about this fact.
12 ga Remington Core Lokt sighted 2 in high at 50 yds = 0 inches at 150 yds
12 ga Lightfield Exp sighted 2 in high at 50 yds = -9.7 inches at 150 yds
