You'll start looking for a 260gr boolit to fit in there. The argie is the one rifle I don't recommend you try to do a throat pound slug on. I want to be on the safe side due to reports of pressures and these 2 lug small rings. I use factory Norma cases and formed cases from various brands and makes of 8x57 and 30-06 cases. Best accuracy seems to be in the 1800 - 1900 fps range. I use a 3/4 gr Dacron filler over the powder. I've found excellent accuracy with 4895 under the Lee bullet in the 27 - 30 gr range depending on flavor of 4895. I use Lar's 2500+ or NRA 50/50 lube with no leading and excellent accuracy. The RL alloy bullets are sized, lubed and GC'd in a. I just lube and seat/crimp a Hornady GC on the COWW alloyed ones in a. The ones I've slugged that have excellent bores all slug right at. ![]() Most of my M91s also have "tight" barrels I guess from the reports mentioned in other threads. The COWW alloy will drop from my older single cavity at. The AC'd bullets have a BHN after 7- 10 days of 14 - 17 and when WQ'd they run around 22 for the COOW alloy and 18 for the RL alloy. These days mine are most often cast of COWWs + 2& tin or a mix of range lead I have (high antimony content) with lead a 70 - 30% and then 2% tin is added to that. For many years I have had excellent results with the Lee C312-185-1R over most any flavor of 4895 including IMR4895 in numerous 7.65 Argentine M91 (currently have 3 of them) and M1909 Mausers.
