Thanks for the reply. The load data was in the pistol reloading section of my old Speer manual.I checked my newer manuals and the Hodgdon reloading site, I don't see any recommended loads for 30-30 using H110 /296. In an old Winchester book (1978) I found a load for a 110 grain bullet but none others.
Over the years I have used a lot of 296 and H110. It is simply the best powder I have found for magnum pistol cartridges.
I have found it to work best near the top of recommended loads as it gets erratic if the case is not filled at least 80% and you have to use a magnum primer to get consistent ignition.
If you feel like trying the load you found and you have the components I don't see why you shouldn't. If you are looking for a reduced velocity or light recoil load that should work. If you get any deviation in recoil, muzzle sound or "light" or delayed fires (hang fire) then stop and disassemble the loads.
748 is what I load normally. But, seeing the 296 load in the pistol section and no 748 to be found in my area for resupply...desperate times, desperate measures.That's an awfully old manual to be using. Got anything a little newer? The Lyman 50th manual lists W-W 748 as best for the 130 gr. bullet. Sorry - this doesn't really answer your question, but the best I can do in the early morning hours.
That's what I would have expected. The case fill is in the 40-46% loading density range, right where Dr. Lloyd Brownell's study showed very erratic pressures, including, on rare occasions, pressures that were double the SAAMI limit. I would treat those old loads as potentially very dangerous to the shooter and gun.The H110/W296 twins were “popular” in loading manuals ~20+ ago, listed for cartridges like the .30-30, .45-70 etc. I tried them in the latter and discovered what a large ES really means...over 250 fps. As expected pressures were also very erratic.
