I had a beautiful sporterized M98 for several years that belonged to a neighbor. He'd never fired it, I talked him into letting me have it to see how it fared.
With some old Federal 170gr factory loads, it shot dead-on at 100 yards (Lyman receiver sight) and IRRC, about a one inch 3 shot group? Using my 150gr Sierra loads, it put three into a tad less than an inch at 100 yards, maybe an inch to the right and over an inch higher.
That wasn't a particularly stout reload, but some quicker'n factory loads. Would've liked to have bought that rifle, but he eventually wanted it back and refused to sell it.
