I have a 9.5x57 Mannlicher Model 1910 rifle in only fair condition.
It came with 2 pkts Eley red/yellow boxed solids and a few Eley SN rounds which I have fired off.

I load reformed Win 30-06 cases using RCBS dies from Huntingdons.
I have used the Woodleigh 270gn solids, on targets only, and ADI AR2208 powder - 42gns.
A while back I bought 100 Nosler 270gn RN solids, but have not tried them yet.

The rifle is SWEET to shoot - almost as tame as a black powder rifle. I don't group it, or use a chronograph, so my data does not offer much help - sorry!

I also put in some effort trying to find a cast bullet load using bought 220gn .375 projectiles, but had serious trouble with gas blowback in most loads due to the projectile departing before the case expanded to seal the breech. I gave that up.

Edit: Bought it in Harare in 1998. Has express sights, and set triggers with the rear trigger removed.
