Nice looking set up. Classy looking with the old 3x Weaver on top. I had an old 4x El Paso steel tube on my Whelen for about 20 years. Last year the adjustments started getting sticky/erratic so I replaced it with a 1.5-4.5 Bushnell Elite 3200. No need for higher magnification on a Whelen.
That's a good group you got there. I get slightly under 1.25" at 100 meters with the 250 H-C on top of IMR4064 or IMR8208XBR. (both at about 2450 fps). Hornady 250 SPRP's group slightly tighter (about 1") but the H-C's are still my "go-to". They've accounted for a pile of game for me and I trust them to work without fail. Besides, that .25" doesn't make a whit of difference on big critters at Whelen ranges.

What man, on his death bed, ever lamented, "God, I wish I had spent more time at the office."
