Oh yeah, love me a lil' Model Seven! My 1st bolt gun was a lil' Seven in .308, and they just grew on me from there...
My GreTan .17Predator is on a Seven, as well as my K&K 6x45AI and 6.5 SAUM 4s. All feed out of AICS based mags, via PT&G DBM. Runnin' a DBM system with a single feed AICS magazine really opens up the potential for the lil' Seven. The sharp shouldered 6x45AI and short necked .17Predator (.17-223 Imp.) both feed like butter!
.17Predator, in an (AICS based) Accurate .223 magazine:
I believe Badger & CDI also offer DBMs for Sevens, as well. And CDI will inlet your stock for their DBM, just send them your stock when you purchase!
Several chassis companies now cater to the Seven.
And, as stated above, McMillan & Manners will inlet for a Seven. When PT&G finally came out with their Model Seven DBM, I sent one to McMillan, so they could write an inlet program for a GameScout I had on order. Came back, perfect! And now they have the program on file...
As for some specifics, on the SAUM:
This action was originally a .300SAUM, so the ramp itself is already 'tubbed out' for those short,fat cases. I did ask my 'smith to notch the feed ramp, so that I could run 130s & 140s in the 2.940" max. range. Same as the other two, this one feeds like a dream!
Pic, with a 140JLK @ 2.935", no problem feeding: (I run 130s @ 2.850" just showing the space allowed from notching the ramp)
Have heard about enlarging the rear action screw, but all mine have the small screw. A good bedding job seems to work fine, I use MarineTex for my home jobs...
Have fun with your Seven!
