I think 196-200 gr bullets are ideal in the 8x57 and the advantage of 8 mm vs 7x65 in my perspective is the use of a bit heavier bullets, lower velocities and the use of shorter barrels without loosing to much power.

Norma oryx is a chemicaly bonded bullet, quite soft, and is very popular in Sweden. However, I like the woodleigh RN very much and will try both the 196 and 220 gr. Another choice is the 200 gr nosler partition, accubond or perhaps Sako hammerhead.

I believe my gun is regulated for the oryx - so how shall i think when i'm going to reload? The Norma factory rounds gave in average 2330 mps in my 55 cm barrels. I think its possible to reload a 196 gr bullet up to about 2380-2390 mps within safe pressures, and perhaps tighten the regulation between the barrels, because i guess i have to increase speed a bit to decrease the distance between the o and u barrels?

I must try to shoot without the scope as well, a good point.

I use Norma powders, preferably 203B but also URP (probably to slow though).
