1. 7,62x54r russian- Don't load for this one. My 91-30 shoots well enough with the silver tip surplus.
2. 8mm mauser- My K-Kale turk, scoped, uses 150 Hornady sp with a nearly compressed load of H4350. Not super fast, not max pressure, but it consistently shoots 1.5" at 100 yards. I have killed two small deer with this load. Excellent results from double lung hits. Most of my brass is re-formed and trimmed 30-06.
For my as-issued Yugo, I use whatever bullets (150 Hdy, 185 Rem.) and enough Blue Dot to regulate the sights. I can give you a safe range if you are interested.
3. 7mm mauser- Don't have one, yet.
4. 7.5mm swiss. #1 load for my scoped K31 was 150 CT Partition Gold Moly (they were cheap) and IMR4350. All my 7.5x55 brass is reformed 284 Winchester. I have also used 150 Hornady sst, 165 Hornady sp, and unknown 180 round noses. Powders included IMR 4350, IMR 4064, H4350, W760, and surplus wc846 (cheap, but not good.)
5. 6.5mm swede- In my wife's 96 Sweede, Rem brass, H4350, and Remington 140's, or Hornady 129s.
6. 7.5mm French MAS. I have the rifle, but no dies. I have been using low pressure loads and necksizing. I have used 147 fmj surplus and Blue dot. I don't recommend the load, or doing to your Mas 36 what has been done to mine. It was a Santa Fe sporter I got for free! It has a 16" barrel, sporter stock, and a safety added. The safety didn't work, so I removed it. I turned the plastic rear sight into a peep by epoxying a cut off case head as the aperature.
7. 7.62x39 russian- I don't reload for my Yugo SKS. The golden Tiger brand was good enough.
8. 30-06 springfield- In my 1903 and 1903a3 sporters, I have been hunting with H4350 and 180 grain round noses. I also liked 57 grains h4350 and 165 Hornady sp.
My peep sighted m1917 is using IMR 4064 and 150 grain Hornady SST. I wanted to use the 180's, but ran out of sight adjustment.
9. 308 win/nato. My only Milsurp 308 is a trainwreck of a type 38 Japanese, rebarreled. Nothing works well in this rifle!
If anyone wants specifics, let me know. I keep good records of what works, and what sight settings I used.
