"When I inspected the brass post-firing, I found that an arc of brass had been skived off the base."
This doesn't sound like a shoulder bump issue to me. I'm thinking cartridges base or web area not being properly sized, hence grinding the shell holder allows slightly better sizing in this area...
I'd lean toward a 1/4 bore, 250 Savage or 257 Roberts. Why? I don't have anything in .25 caliber and new projects are always fun and of course I like short actions. My 2 cents anyway.

Thanks for info, after rereading your post I see you mentioned .5 micron. Which with research is obviously the ultra fine product.

Miss Sugar is sure a beauty. I always favored the white colored Shorthairs when I bought or kept a pup. Seemed easier to spot them especially when locked on point in CRP or whatever wind blown crop the birds decided to hunker down in.

I too have had good luck with IMR 4198 with 50gr Blitzkings or Ballistictips in 223. Though last check that barrel is slowing down a bit. Those same bullets in 22-250 do well with Varget and of course H380.

While not on your short list, I've been happy with set of Leupold BX-4 Pro Guide HD 10x42. Decent glass compact and lightweight. Street priced near $500.

Jimbeaux I would like to hear how this project goes for you, as I will be doing an identical load development for my grandsons Savage storm. My loading room is not yet set up after a retirement move but when the time comes I'm sure your experience will be helpful.

Yeh I bought him the Savage Lightweight Storm with adjustable LOP and a decent recoil pad. Sweet little rifle for the price.

Same situation here, I just ordered 120 grain Sierra Pro Hunter bullets from Powder Valley for grandson. Looks like BenchMark may be a light charge according to Sierra #5 manual.

With the 140 and 160 ABs I get good accuracy and decent speeds with H4831sc. The 175 Interlocks do well with IMR 7828 out of my 7wsm. I haven't found a need to hotrod this rifle though. Good luck it's a fun round to work up.

My experience with my only Lapua purchase, after a single firing I noticed what I would describe as lamination on 3 cases. Contacted representative and sent pics, he requested I return all 200 pcs for replacement. Which involved demilling and soaking unfired primers. The payoff? 200 pcs of new...
