I recently tried a Model 7 for the first time and it quickly became my favorite rifle of all time. Schnabel forend and all, it fits me like a glove. Specs are 308 / McMillan
M7 stock / #4 Krieger @ 20". I see something very similar but chambered in 223 in the near future.
Love that rifle. As you are finding out they are very addictive. I have 2 customs on the seven action both with heavy-ish barrels like yours that are sweet rifles
