Sliver, well it kicks like hell with my handloads, I won't let my junior shooters shoot it. But these loads of mine are stiff.
The Old Western Scrounger used to sell loaded RWS ammo, I believe. I picked up two boxes of Yugoslav Privi Partisan factory loads at a gunshow for $25 per box of 20 last month, in Canada.
Why would you not load for a rifle so chambered? RCBS have the dies; bullets and brass are available, plenty of data.
One important point, I have a book of reloading big bore rifle ammo and it says you can use 30-06 brass necked up. NO, not practicable, the 9.3x 62 has a bigger base diameter, which is why the writer Dave Scovill of Reloader Magazine fame created the 366 Scovill, a 30-06 case necked up to .366, (9.3)
Sort of re-created the 35 Whelan really.
