I shoot allot of rounds so I buy cheaper bullets for 98% of my shooting. The Sierra game king 150's (Spitzer Boat Tails) are a good choice

I also do the messy home moly coating.

Sierra Bullets - The Bulletsmiths
My 6.5 Sherman holds 75 grains of H20 to the top, so the .270 would be slightly more. I do have a spec sheet for my 6.5 and my 300. The .270 would be the same except for the neck. Neck length on the .270 would be around .304".

No, I have a gunsmith that does that but I have the reamers and go gauge. You could use the 6.5 reamer as long as you have a .270 throater.......Rich

Re: 270 Winchester Ackley Improved

where did you purchase the reamer? You have my interest up. I would like to go the 6.5 sherman route on my next build this spring. Should only have to neck size too, correct?

I had Dave Kiff build it. I have a hydro form die that I use to form the cases for both my 6.5 and 300 but I have also fire formed them. If I use .270 cases for the 6.5, I simply neck to 6.5 and leave a false shoulder to headspace. I use 11 grains of red dot, fill the rest with corn meal, and a little cotton to hold it together.......Rich
