I've been away for a while so I'm not up to date on some things. I would enjoy hearing from others what their choice of replacement for 4759.
Been trying to catch up on some info because of my absence. Look forward to reply's to my query.

I "think" some interchanged VV110 nearly equally with 4759 but you need to verify that for sure. VV110 is not always the easiest to find either and a bit pricey but it burns pretty clean. I know I have used 4759 and 110 interchangeably as a starter powder in duplex and some lower charge weights for other purposes.

The huge advantage of 4759 was it was very bulky.
Bulk results in low pressure, hence its use as a cowboy powder.
In moderation, fast powders are beneficial when combined with slower powders, to duplex loads.
The use of two fast powders can be very dangerous.

VV110 is faster than 4759, always start 2-3 gr less than 4759. I use both & use them with bullets 250 gr & less from my .45.

N110 is definitely faster than 4759 unless you have some old metal can 4759.
In 50cal with sabots i do like N110 with upto a 250gr bullet. Not a big fan of it with heavier bullets. It can get rough on sabots quickly. ATM i dont see a good option in faster powders for a 300gr bullet. Speed from 5744 is poor and recoil from N120 is more noticeable but its a great powder too.
4759 was a great all around powder and nothing really replaces it for a 50cal sml.

I am sure glad still have 3 lbs. The way I use it, I will probably never run out.

My Thanks to those that have responded to my query.
I too have a few pounds of 4759 left but like the saying "All good things must come to an end".
I have not found a supplier of VV110 in my area so that powder is out.
Going over some thoughts and previous notes I found a mention of trying IMR 4227 again (not H4227 which I understand has been discontinued).
Originally I started out with IMR 4227 on light resistance loads with 250gr bullets and it fired. Once I switched to H4227 my misfire problems began.
Now add to the fact I have good resistance loads and a recessed breech plug for a smaller volumetric column to start my powder burn then I've got a good chance of making it happen. The real test will be firing a 200gr bullet in cooler temps. For now I need to focus just on getting back into the swing of things. This future test will be on my to do list.

4227 with enough bullet weight and a good plug should be far less problematic than the old days. Personally i would probably avoid using it with 250gr and under....UNLESS you thoroughly test it in your rig first.

You can always duplex loads, but VV120,H4198 n RL7 sure work well

Definitely testing is required to answer a question that's been nagging me about IMR4227. Some fun is learning from final results and in this case put a nagging question behind me. Ed |

How would Trail Boss be? It sure is bulky?

Trail boss is more or less a no no. It should not be compressed and performance sucks.
Ive heard from several other NULA owners that tried 4227 in theirs. They said it goes bang just fine. Big difference though is the NULA plug is shorter and seals great.

ET,
The best load I ever shot in a .50 was a duplex of 14/61 using N110/H322 for speeds of 2600fps with a 250grain bullet in the .50. Tried many others over the years but always came back to it. Several of the guys I hunt with still use it exclusively today. Never could find anything close to 4759 performance overall as a single powder load so just kept duplexing.

I duplex with 4759 as the starter in part to save on the 4759 I have left and for perceived cold weather ignition.

Thanks for sharing that enticing load and will note it in my book. For me I would be happy with 2500fps and reduce my drop slightly at 200yds. That reminds me I need to dig out my chronograph that's been packed away for some years now. Just had a look at the PT for that load and 40K is good for me. Ed |

Ed If you duplex with 4759 then go with 4759/H322 at 15/60 with 250 grain bullets.....will hit right at 2650 and excellent accuracy. Make it last a lot longer LOL! |
