Have a ball.

IMR-4350 From 46.2 grains to 54.0 grains
Winchester WLR Primer

Guys thanks for the info!

I've used the SGK's in the 270 and was dissapointed with the performance in comparison to the Hornady Interlock.

For what it is worth 11 out of 11 whitetails I have shot with the Sierras have dropped on the spot. I used 130 grainers at 2900 fps.

You should really obtain the IMR and Sierra manuals before loading, IMHO.

I'm not a 270 fan. What stops the 270 from true greatness is the bullet. The 270 makes big holes that are hard to eat around, especially at close range, and this is where a premium bullet will pay dividends. The good news is that bullets seem to be improving every year and this alone bodes well for the 270. It wasn't too many years ago that Nosler's B/T wasn't a good hunting bullet in anything smaller than 180gr .30 calibre non-magnum rifle, fortunately that has changed. Same is true for the 25-06 as it was never a question of the cartridges power, rather it was a question of bullet integrity.
I realize this is a non-answer answer to your question, however since your experimenting with loads give a bonded bullet a chance.
