After much debating on which 270 cal cartridge to go with and reading all the great threads on the different Sherman designs I opted to do my first semi-custom in a 270 Sherman and couldnt be happier. Elkaholic (Rich) was very very helpful in answering all the questions that I had throughout the process and facilitated renting his reamer and getting dies to me. My build is on a Rem 700 long action that was trued and I dropped in a Timney 510. For a barrel I went with a 27" finish Lilja 1:8 twist 3 groove #5 contour. I opted to use the factory stock that came with the rifle since it is in such good condition and I am partial to nice walnut stocks. I topped it with a Talley 20 moa base, NF ul rings, NF 5.5-22x56 and vortex level. The rifle weighs in at 11.2 pounds with scope and accessories. I had all the work done at Diamond T Rifle Shop which was top notch!! I decided to only shoot 165 Matrix and larger bullets (hopefully the 170 Berger comes to life soon) out of this so I had it throated for them specifically. I fireformed 100 rounds of winchester brass then went to work breaking the barrel in with my test loads being loosely based off of 280 AI data with 175 bullets. This put me really close for shooting the 165 Matrix. During breakin I shot a ladder of RL 33 and IMR 7977. The group on the left side is the ladder of RL33. The center group is IMR 7977. I hit my max with RL 33 at 64 grains and 60 grains with IMR 7977. The lone shot up top is my one shot with retumbo which was a total fail and has left me puzzled (a question for later). Unfortunately I do not have a chrono so I cant tell you speeds yet but now to the good stuff... I have a SHOOTER!!! The tiny group to the right of center is my first 3 shot group at 200 yards with 62.7 grains of RL 33... It measures .320"!!!!! Next I plan on trying some groups with IMR 7977 and figuring out the Retumbo. Also I may try some HBN and see if it will let me get some more speed and save my throat some. When I get some more data and speeds I'll add to this post. Just thought I would share.
