223 brass rmr 55gr fmjbt and 24grs varget
Maybe he doesn't know how fond of tac some of us are.52,000 CUP is 223 maximum working pressure. Most if not all, Varget maximum loads Hodgdon has listed are compressed. This tells me its a poor choice of powder for maximum loads/pressure.
Then the rmr 55gr fmjbt has very little bearing surface. This reduces pressure. Add in the cartridge slop in the Savage chamber & you have brass that is not fully expanding to the chamber, or extra head clearance.
Primers can back out.
I would change to a faster burn rate ball powder for the 55 gr bullet. No compressed loads. The pressure would be more normal and expand the brass on firing.
I use IMR 4198 for 55 gr plinking loads, but it doesnt work well in powder measures ,like ball powder.

Maybe. My Ruger American .223Rem uses the rotary magazine - I prefer it over the long, dangly, constantly-in-the-way AR-style mags in a bolt gun - and is typically Ruger about OAL . IOW" it doesn't like longer than SAAMI spec and it doesn't like single-feeding. For a cheap, no-frills rifle it shoots pretty good and if it gets left out in the weather I'm not heartbroken.The OAL can be longer for a bolt action.

+1I would try some factory ammo
…which supports the suggestion you’re setting the shoulders back too far for the bolt gun.Got two factory rounds fired them today no proud primers View attachment 1037006
Maybe I've been handloading to long but my chamber is the only case gauge I use.As long as they fall between minimum and maximum should they not be sized properly?
