I haven't used 4895, but I use 3031 and 4064 with success. 3031 is weird in all of my Enfields as in the charge doesn't really change the point of impact or size of the group. I've had up to a 4 grain difference in charge and they are still landing in the same area, with the same size group (1.25"-1.5" in a mk3) 4064 I've done more testing in my LB No.4 mk1* with 2 groove. It likes the Sierra 180's and the Hornady 150's, the last batch I worked up were impacting 6" low at 100 but sub-moa. It is not bedded, but has a new forend that I fitted and I suspect that has a bit to do with it. So I guess what I am saying is my No.4 really likes 4064 and my No.1's really like 3031 and 4064 in that order.
