You may not have any but the old IMR Handloaders Guide shows 11.0 gr of SR4759 in .30 Carbine at 1545 ft/sec with a 110 gr bullet. And you could probably go with less with little risk since it's a powder designed for reduced loads.

If Hornady says not to load H110 below a certain point for rifles but then publishes lower loads for Contender pistols then that is a cock-up on their part IMO. The older Winchester instructions (10th, 11th, and 12the Edition IIRC) are much clearer and state (again IIRC, I am not going to drag them out this time of night) to not load below 14.0 gr 296 with a 110 gr bullet. The standard "do not deviate" Winchester load for 30 carbine is 14.5 gr WW 296, 110 gr jacketed bullet, and a WSR primer.

Regarding SEE and double charges, most reported SEE that I am aware of occurred in 6.5mm Swedish and similar calibers with slow powders. It is quite impossible to to double-charge RL-22 in a 6.5mm case.

I am not trying to stir things up, but what I read as the tone of your first post really offended me. In my line of work, folks that "ignore dire warnings" are lucky if they only lose their livelihood. I have become risk averse because I have seen the results of unwise risks and bad decisions and frankly some bad luck. I have lost friends and co-workers. It is not fun when you know the wives and kids.

So, please be safe and please accept my apologies if I came off too strong.

My guess is the lowest loads in the rifle section are the lowest that will reliably function the rifle.

Loading companies extensively test their published data, so I have no qualms about using lower charges in a handgun, if the data come from a reliable source (in this case Hornady).

No, W296/H110 as a powder has limitations that are well known in the industry that are completely unrelated to what firearm the cartridge is being used in. If you are going to use this powder, then you use it in full power loads. If you want to play around with lesser power loads, then you use a different powder. Personally, I don't use this powder because of it's inflexibility.

I'll be picking up a Blackhawk in .30 carbine tomorrow. I'll put together some rounds with 2400 powder and let you know how that works.

On a side note, when I first purchased it 10 days ago, I was thinking about knocking over a liquor store with it. Fortunately, Kalifornia made me wait ten days to pick it up, and during those ten days I realized maybe that wouldn't have been such a great idea....

I guess Commiepornia was looking out for you!

Ignore those warnings and you may wear part of the revolver backstrap or cylinder as a hood ornament.

If you like living dangerously please race superbikes or hang glide. We who enjoy shooting and reloading have enough trouble without listening to your dear widow call for more restrictions on handloading due to your recently departed stupidity.

Google is your friend should you wish to learn more on the subject.

I mean no disrespect to you, but others have been killed by ignoring good reloading practices and by ignoring warning signs at the range. Out of respect to their families I will not name names or circumstances here.


BTW I believe IMR-4227 can be downloaded safely and may achieve what you are trying to do w/ H110.
THIS just happened during the CMP Talladega D-Day matches. A guy that happens to also come and shoot at our club was using "reduced" loads in his M1903. Don't remember the powder (an IMR specifically meant for it apparently?), but it was about 1/2 the grain weight of a usual .30-06 load. Third shot, his 1903 literally exploded all over the range. He only has eyesight because of his safety glasses. The destruction was amazing. Me, I'll stick with something in the normal range.

CMP collected his gun for inspection, but they also mentioned this phenomenon upon initially understanding the situation. It can cause something around 10x normal pressure.

I'd say if you want to safely reduce recoil, use a different gun/cartridge.

I used reloading data from the 9th edition of the Hornady reloading manual. If you are aware of any data in this manual that may be dangerous, perhaps you should notify Hornady.

If I corectly read the article you posted, I believe I can summarize it as follows: "SEE occurs only under circumstances that cannot be duplicated, measured, or verified." In my feeble mind, this puts it in the category of disintegrating op rods and spontaneously detonating low number Springfields. My uninformed guess is the anecdotal cases of SEE are actually due to double charges.
What a great response!!

I think that means:
Stick to recommended loads
