Webby Posted January 25, 2017 Report Share Posted January 25, 2017 my manual puts it top of the list for 56gr and 2nd for 69gr N550 being top. N540 is reputedly a bit of a barrel burner in 308 anyway due to nitroglycerin content. Link to comment Share on other sites More sharing options...
munkjack Posted January 25, 2017 Author Report Share Posted January 25, 2017 Thanks Webby interesting about it being a barrel burner There is a part opens tub for sale not far away from me I think I'll pass on it as I've got a shinny new barrel on my rifel and don't want the expense of a new one for a Wee while yet.

duey Posted January 25, 2017 Report Share Posted January 25, 2017 The 5 series powders burn hotter than the 1 series powders and they only really effect the barrel life if you do a lot of string shooting as they do in bench rest And as already stated N550 would probably be better than N540 Link to comment Share on other sites More sharing options...
