For those who are interested in reloading for your 270 Semi Auto.
Well, a while back I had feeding trouble trying to load 130 Sierra SBT, 210 primer and IMR 4064 in 270 Win for my 7400 autoloader. I lowered the COL from 3.3" to 3.275" with 47g of 4064 and ejecting was fine. Accuracy hurt a little, but I still am consistently getting 1.1" groups. Hard for me to believe with a 7400. With factory Corelokts, it always got 2"-3". Tried 47.5g, and 48g at 3.3" COL and groups opened. Anything below 47g and it won't load the new round properly. If you try to load 3.3" with 47g, it won't load properly.
Seems to be a small window of operation for this round in a Semi-auto. At least with 4064.
BigC: 130 gr sp hornady 3.275" 9 1/2m rem primer nickel case 2900f/s 48grs imr4064 factory crimp all loads for the 270

3100fps?? Are you sure? Thats movin for a semi-auto. I might give it a try. I was going to try Varget next, but with that speed, I might try your load.
Bigc , across a chrony at 10' from the muzzle 3087, 3109, 3104, 3091, 3091,3103, 3089, 3105, 3107, 3094 , Avg. 3098 close enough. with standard primers velocitys were 3070f/s Dave
