Idared,
I inherited a 35WAI from my father. It was a gun he was very partial to. It was built on an Interarm action. I can't recall his exact data and don't have it handy at this moment...I'll be glad to share what I do have from his writings. IIRC, the gain over "book performance" was nominal...about 75-100fps. Dad wasn't known to load below max much.
If you want, PM me and I'll share what I have. I know he was partial to R-15 in it. He whacked a nice bull elk in Montana with it several years ago and said it did a nice job.
