Have any of you guys had luck with loading 90gr Sierra HPs in a 270 Win? I wanted to try those buggers this summer and see how they do on a nice fat groundhog. Just looking for a good powder to start with that someone else may have already gotten good accuracy from.
I tried some on paper just trying to work up a load. I called Hodgdon Powder b/c I already had some Varget on hand. They reccomended 52-56gr I belive all my books are outside at this time. I also use CCI 250 mag primers already so that is what I used (Hodgdon said that they would probably add 5-15fps over 200 primers.) Hodgdon had an estimated velocity of 3595fps.
With that load my results were about 6-7 inches high at 100 yards. Those results were out of a rifle that is zeroed at 200 yards with 140gr Nosler Ballistic Tips that are loaded with 58gr Hodgdon 4831sc and CCI 250 mag primers, all loads are Winchester brass.
Maybe this will help?

I haven't use the 90 gr Sierra, but I use the 100 gr Hornady spire point for practice standing. Also I used it as my load for position shooting before I got my Remington 222 Varmit. I use the minimum load in the Hornady loading book, 50gr of IMR 4350 with a CCI 250 Primer. With my 4x scope I normally keep 10 shots in an 1 1/4 @ 100 yds off the bench. It has very light recoil.
Thanks guys. I appreciate the info. I've got plenty of IMR 4350 and IMR4895, so I'll start with those. I'm not expecting too much in the accuracy department, as this is an old JC Higgins 270 Win that used to be my grandfather's. I spent this weekend floating the barrel and bedding the action, so it will be interesting just to see what I can squeeze out of it. Who knows, I might be pleasantly surprised.
