Sure IMR can be used, but out of all the powders with the same numbering between Hodgson and IMR, 4831 is vastly different. IMR seems much faster than H4831sc. I would drop the load 4 full grains for IMR4831. Work up noting pressures.

Hodgdon's webpage has extensive data for 130gr and 140gr.

Default Imr 4831 vs. h4831

thanks for the reply! I was just curious as to the difference I have other options, and I may try the reduced load.

Hodgson has the data you need. For some reason 4831 works vastly different in small cases. Cases like 300winmag and RUM, they are almost even.

Bigcountry is right. Hodgen works differently in smaller cases being a slower burning powder. I use IMR 4831 in my 270 and H 4831 in my 300 win mag. You can load a lot more IMR 4831 in a case vs H 4831 because it's smaller pellet size and it burns faster and causes more pressure. But in the 270 win it's a good powder to use. You can fill the case close to where the bullet seats an have a great load. I would stay 59 grs or under of IMR 4831 until you've test a few rounds through your rifle. Then you can start tuning your load from there. One 270 win I have likes 58.6 grains of IMR 4831 and another 270 win is very accurate at 59.9 grains. Both are loaded with 130 gr bullets. You may want to start at a lower powder charge using 140 grain bullets. I have not loaded any 140's yet nor probably ever will unless I get a new rifle.
