I have had some ignition problems with 4227 when I used it in a savage muzzle loader. Does this powder also have ignition problems when used in cartridges ?
especially in cold weather.

Also, would 4227 be suitable for 204 ruger loads or even 22-250 or 223 ?
 
Both 4227s are excellent powders, with no ignition problems in cals. it is mean't for, large Mag. handguns(the.44Mag.) and small rifles, ie: Hornet, my Whisper,25/20, and small ga. shotgun(.410 I think), for bigger carts. like the ones you have or larger, it is usually used for reduced or slightly reduced loads. It is faster burning then the powders usually used for your purposes, so you can't get top vel. without higher pressures, so...not optimum but...ya know...
 
The 4227's are considered the dividing line between slow pistol powders and fast rifle powders. It is my favourite for magnum pistol and small capacity rifle loads, but I have not had good success with it for reduced loads in large catridges. It has a minimum pressure requirement that might not be met with the load you used in the Muzzleloader, and that can result in very erratic velocities, unburnt powder and possibly bullets that don't leave the bore.
 
I have had the same problem. I left my Savage MLII loaded from the first week of November until the second week of December and stored inside (no primer).
The last day of the deer hunt I tried to fire it but it would not ignite. I tried this twice. It was cold. I took it home, let it warm up and the next day put a primer in it and it fired no problem. I was using IMR 4227 and a CCI 209 primer. Now I don't know whether the powder is heat sensitive or the primer is not hot enough. I suspect the latter. I am going to rectify the problem before the next December deer hunt.
 
I thought those savages needed IMR 4759 powder? Not my cup of tea as i don't care for those old time period correct muzzleloaders, but I'd look into it before next season.
