Most commercial ammo is anemic and i want a mil standard hot load
Not turkish ammo hot but close. I bought Mitchell Mausers so i could have good bores and not a safe queen. I buy rifles to shoot. Second mauser coming i will be having a gun smith put on a Short Side rail from accumount or rsm mount so i can make it a mauser sniper with a repro scope
understood but like I said your approaching max chamber pressures with those powders at 45 grains.
I would maybe load up in 1/2 or maybe 1/4 grain steps 45, 45.5, 46 looking for pressure signs and accuracy.
I run the 200 grain Nosler custom comps out of a old well worn K98 mauser and so far my best accuracy under 2moa has been in that 2400 fps range. Im sure with good bore and a scope these loads will get down to that 1moa area.
Most US commercial ammo is loaded light to around 35,000 psi. Norma and RWS both load some hot 196 grain loads closer to 2600 fps but I think this is more due to the expansion of the soft tip bullets they use.
If your punching paper and steel, load to accuracy at the distances you will shoot most often.
Looking forward to see your sniper project.
IIRC the "mil spec" for what we like to refer to as the 8mm mauser (S,JS,IS) was loaded with a 154 grain pointed bullet FMJ to aprox 2800+ fps which you can easily do with several powders and stay well with in the max chamber specs.
I have loaded the hornady 150gn SP with 50 grains of varget ,,,stout rounds and for my end use complete over powered.
I tried the hornady 174gn match .323 and loaded them progressively from starting loads to max loads in the hornady manual 7th addition and I can tell you when you get close to max loads its not much fun shooting a match with those loads.
Lost those notes to a water leak few years back but IIRC those where giving good solid 2- 2 1/2" groups with irons with around 42 grains of varget
