I feel the H4895 is alittle faster. But as you know the H4895 is an extreme powder and temp insensitive, or less sensitive. So I felt better using it. It made for some very accurate ammo. I used Fed 210M primers, but Fed 210 would work too.
I used to develop ammo and test rifles for a manufacturer about 12 years ago and I used H4895 for 150-165gr loads for specifically semi autos. I didn't develop 180gr ammo for semi autos but I think I'd follow these guys suggestions.
