See what you mean about the diiference in OAL. If I were you, I would stick to loading to the orginal OAL and simply use better bullets and care and attention for better results. After all, no factory ammunition, apart from GP11, can compete with your own, right?
Load to the shorter manual specifed length rather than my measured length? .323" 200 grain bullets (as in, please forgive me bullet heads
not cartridges. Which bar the fmj surplus I've never seen for sale but apparently is the likes of 150/175grain soft point) are difficult to find. I thought sierra match king HPBT would be the best I could find. Else wise it's stuff like 198grain PPU FMJBT which is a fair bit cheaper (£10ish cheaper per 100) The discrepancy over the OAL being +\- 0.01" was from 10 readings of trying to measure the chamber OAL not the completed cartridge. I usually load and check every cartridge to be within 0.001" I weigh individual charges fwiw regardless of quantity to be loaded. I wanted a solid figure and see that standard deviation between measurements was negligible. The way I was doing it was not consistent enough, I hope your way when I get my calipers back and start taking measurements will be. The surplus ammo available to me is frankly dog do do!
Remember too, that your military Mauser, if that's what you have, was doing just fine if it put three shots in 90mm at 100m, let alone the minute groups that folks seem to think are their birthright. Anything that did better, just like the Lee-Enfield, was set aside for 'better things'.
yeah I have a waffen stamped 1937 kar98k, large ring mauser. I'm happy if it will hold in the black. Though it seems to be at best a 5-7moa ish rifle but I'm only a young lad not used to firing these big scary bangers
practise with it will help the groups I'm sure. Incidentally I will be putting in far a variation as I'd like a 'proper' sniper version too. Better things indeed
It's howling down with rain right now, so I'm not going out to the shed to check your VARGET loads for the 8mm Mauser, but please take great care not to get any round too
short - even a slight difference, especially with the teeny calibres like the centre-fire .22s, can be very much NOT what what you want.
Exactly, although I'm also aware/concerned that loading a cartridge longer causes big pressure spikes too, which links back to my first answer to the above. I guess if I did load 0.005" off the lands and progressively further away (increasing bullet jump) that I'd need to go right back to the mid point in the sierra book and proceed carefully. The annoying thing was my first loads (42ish grains varget from memory was putting the bullets in the mantel (2-3foot low)
