Home Forums Hunting & Shooting Handguns LOAD DATA CAST 41cal 265gr WLNGC LBT CAST BULLET

one thing that nobody seems to comment on other than me with H110 or 296 is the very narrow spread in load amounts between minimum and maximum amounts.

In regard to your comment, H Bowen also remarked that you didn't have to run LG at full throttle loads for good ignition and burn as H-110 seemed to require and that it was also cleaner than H-110.

In not a handgun expert, but in setting up a RRH 45 C with him, those were his words to me.

I find H-110/296 to burn very clean with heavy bullets and full power charges.

I agree...I ditched the shot shell powders years ago and have been using nothing but H-110 in my 41 and 44 mags. 296 was also good giving excellent accuracy but seemed temp sensitive in extreme heat so I stayed with 110. I never have used mag primers with 110 but a good healthy crimp has always been SOP.

H-110/296 are the same powder just in different cans.

My first 475 was built by Bowen and was the first 475 Bowen ever built and he thought 400 to 420 grain bullets were to big and supplied a LBT 385 grain mold.

There was some lot to lot deviation in the early introduction which was quite noticeable on top end loads IMO.

I find H-110/296 to burn very clean with heavy bullets and full power charges.

Yea, IIRC, his words were you needed to run it (H-110) at top pressures/full charges for it to burn cleanly whereas, with LG, that wasn't as necessary.

Yea, before Hodgdon bought out Win powders. In the older manuals, it took a just a little bit more H110 to get the same velocities.

True about H110 and 296 work the best from 95% and up on max loads. Although my most accurate loads were about 95%. I never went much farther in my Smiths. That was the olden days. I am glad I did it.

That's odd, considering they were at inception the same Olin ball powder. Even today, the powder lots will still vary, even if the data doesn't.

The perusal of several 30 odd year old manuals shows that its about 50/50 in the cartridges both are used. One needs more, or less than the other to do the same thing, without much rhyme or reason, other than typical lot variances or perhaps ambient conditions during testing. Ken Waters Pet Loads also bears the similar results of nothing being similar. Waters definitely did not have any inkling they were the same powder at all.


H110 was designed to work above a certain pressure level with some compression (think 30 Carbine).

According to the makers data of both powders, Lil'Gun is showing the same speed as the H110/296 load at 2,500 CUP less pressure with the .41 cal 265 WLNGC bullet in 41 Magnum.
