I've loaded a bunch of rounds for my .357mag using cast, plated and generic jacketed rounds with mainly hp38/231. I've been given some Hornady XTPs and would like to load at mag levels so will pick up some 110/296, does that powder need mag primers? I'm assuming it would. Thanks.

Forget about the 110, go with 2400.

I agree with Jack regarding 2400. To your original point, follow the recommendation listed in the data. Most if not all data for 296/H110 recommends mag primers. Most 2400 data is given with standard primers.

I'll go with the 2400 then, thanks for the recommendation.

It's much more flexible, you can load it down or up to max. Also, even at max and with a mag primer, 296 leaves unburned powder. It's not the worst thing that can happen to you, but in some cases the unburned powder falls under the extractor and even a little of it can tie the gun up. A quick brush off with a dry tooth brush fixes it, but better to not have to deal with it. at top loads, 2400 velocity is as fast, or nearly as fast, as 296.

I have to agree qith th eother old timers, 2400 is a good magnum powder. It won;t get you the top end vel but is sooo much easier to load with as the range is wider. H110/W296 is a max effort only powder & you DO need to use mag primers for eithre. With 2400, it happily moves along w/ std primers.
