Do a custom search for "IMR 7977" on the top right corner.
 
It is a very hot burning powder. If shooting a lot of consecutive shots it will get your barrel HOT.
Waiting on my borecam to scope my 260AI barrel I used it in. My AI is used for F class and after 20 shots in a 20 minute period you would get blisters if you grabbed the barrel to long. H1000,H4350 and H4831 has never got that hot.
It is a good powder but needs to used right.
 
Thanks for the reply's seems I now have a line on H1000 so will by pass 7977 and stick with would have know and have been using .
