Any thoughts? I'm running out of the old standby Hornady 100gr SP.

Yes. A 700 Classic in the Roberts I once owned shot these (& many other 100 gr. bullets) very well with 42 gr of IMR4064 @ c.3050fps. This was over book max at the time (late 80s) due to the anemic SAAMI spec for the Roberts, in deference to the many older pre-standard rifles in existence, but were problem free in my rifle.

Just checked & Nosler #9 shows the same 4064 data as #2, so apparently the Roberts is still being loaded down? Start low & work upward.
