Panthera - what level of accuracy should I expect to receive?

[bdzjlz]

I have been working with my Panthera to get it dialed in. It is a 700MM version. The slugs I have been testing include the Zan 30.5 and 33 gr, the NSA 31.2 and 35 gr (all of the preceeding in ,217), and the GEN II Patriot slugs in 34 gr and 40 gr, and both .218.

The Indiana winds haven't been cooperative, I have yet to have a day where the wind wasn't 10 mph plus. I have now shot two groups of 10 shots each with four different power settings.

The best and most consistent groups have generally been from the ZAN 30.5 Gr slugs. Today's groups were the smallest yet and very consistent, in a wind of about 10 mph. As you can see, the two group 10 shot average at 85 yards was .80", The reg pressure is set at about 163, the macro adjuster at 23, and the micro adjuster at 3.5. Muzzle velocity is +/- 130 fps. Will probably back the micro off some more and test again.

Most of the other slug combinations were averaging 1.50 to 1.60 inches by comparison.

What level of accuracy should I expect to receive when I get it right?

For that kinda money it should shoot a whole lot better than that.

22 panthera shooting javelin Gen 2 34 grain slugs at 950 fps. Grouping at 100 yards there on the right., can fit them under my thumb, the high and low shots are me getting on target at 100 yards. Others are getting the scope adjusted for zero. I have a 1/3 ipsc target that at 100 it was cake to hit, wasn't able to get out further yet. Will shoot much better after some more shots and warmer weather!

The second 10 shot group is very good. That’s inside MOA. It won’t get much better than that real world in the wind.
This is 20 shots in windy conditions at 165 yards .25 Panthera 600mm. Swinger is 4 inch diameter.

Nice shooting! What weight slug and what speed are they being shot at if you do not mind sharing the information.

I believe Mike (Centercut) was using Altaros ATP smooth boat tail slugs, 49.5gr at around 850‐875fps. I BELIEVE that's correct. That's what he was shooting the 1st time (2 weeks prior) at 200 yds. I'm sure he'll correct me if I'm wrong. The accuracy from that gun at DISTANCE is pretty amazing (as is the shooter behind it!).

I had bumped it up a bit to 885 to 890 fps for the .25 cal Altaros 49.5 grain BT slugs. They definitely outperformed both the ZAN 37 and 41 grain slugs as @Gerry52 will attest. I get about 20 shots from a 250 bar fill.
