i would love to try those buckhammers in my 835. i use 3" lightfields and they are accurate. they're not meant to pass through an animal but use up all the energy inside the body cavity. both loads are pretty close as far as energy at 100 yards. the buckhammers are heavier by about 90 gr. though. i also would like to try those winchester partition slugs. but for now I'll stick with the lightfields. they tend to run a little cheaper than the competition. all i think will be similar in ballistics. you'll just have to see which your gun likes to digest
