First rounds down range were very pleasant; even with full power .45-70; the rifle was a blast to shoot. I did not have any sort of optic on it, so did not do any accuracy type testing; just basic function checking with a few different loads. I tried Peters 405 gr SP, Hornady 325 FTX Leverevolution, and Fort Scott Munitions 300 gr solid copper. Everything cycled perfectly, and loaded fine; the website lists capacity at 4+1; I was able to load 5 rounds into the tube without issue with all types off ammo; almost a 6th, in fact. The low pressure round suppresses well; it was very mild on the ears, both shooting and at the 3 and 9 o'clock of the shooter.
I got an EGW picatinny base installed; I'm thinking a good, low power variable will live on this in the very near future.
