I have a bunch of 156 grain European cup and core bullets, I am not too sure who made them, I have watched them make moose fall down, they work just fine. I am pretty sure that they will work just fine in this rifle. I bought a bunch of prvi brass, and I will measure a couple of fired cases, and if there is any difference to speak of, I will keep the brass separate. I moly coat them, and get good velocity out of them in other rifles. I bought a rifle for some bullets that I bought a long time ago, when you could still buy bullets on Ebay. I bought 60 lbs of 6.5 bullets in 3 models, 156 gr fmj an 156 rn sp and 92 gr Hp for $160 shipped, it worked out to less than $6/ hundred,. it is not a big deal to buy a rilfe for them to shoot over 1500 of one type, if you already have the bullets. Plus, I am a hunter, and I practice shooting offhand etc. Inside an inch from the bench is plenty good for me. Shooting them through the same hole is for others, and mostly for others who use a fancy shooting rest.
