The rifle is a Weatherby Vanguard using Shilen’s Alternut prefit. This is the second one I’ve done with them.

All the brass fired in the old barrel will not work in this barrel , so I still have 40 pcs to work with.
It is hefty coming in at 11.6 lbs.
Earlier in the week we in the mid 90’s with dew points in the upper 70’s , your sweat was sweating. It’s amazing in 6 months you go from -30’s to 90’s here in WI. Factoring in windchill and heat index you’re talking over 150*.
Today’s smoke was better 3/4 mile visibility.
It’s been in the 90’s all week with tropical humidity here. I been trying to strip the paint of the deck and railing , but that just being done in the mornings. Yesterday we got a real kick in the teeth with wildfire smoke from Canada. Most of the day we only could muster 1/2 mile visibility.
Yesterday I received my Shilen 224 Wby barrel. After seeing how the 375 performed I went with them on this project. It is nice that they the Alternut prefits for the Vanguards at a reasonable price.
Both Natchez and Scheels have them , 200gr JSP.

Looking at the 2 targets posted , to me you have double grouping with a flyer. I would have shot the rifle first before sanding off the front pressure points in the stock.
I think it’s hard to get a factory barrel and factory ammo to shoot sub-MOA on any given day. You may come across one lot...
I tend to agree with your assessment on the 0.558 being a bit steep. They don’t have that sleek long nose to help in the BC department. With the larger open tip I bet they will be devastating on game like the Shock Hammers.
