I've had the non pro model for a couple of years now and it's been flawless. I used it last year and was able to make a 170 yard shot on a nice buck. Performance of the ELR worked fine for me as the buck piled up after 50 yards or so with a shot through the boiler room. I use 105gr by weight = 150gr by volume of Blackhorn 209 and have upgraded the ignition system to the Arrowhead Precision breech plug and primer capsules. The furthest I've tested it out to was 300 yards and would have no issues making a shot at that distance on a standing still whitetail. I run a Bushnell 3-12 HDMR optic with MRAD turrets. I really like the muzzleloader, but it is no lightweight and has it's place if longer shots are to be expected. If I'm hunting places with shorter ranges or in the wood, I usually carry my TC PRO Hunter. Just a side not, the recoil with full power 150gr by volume loads of Blackhorn will not be pleasant off a bench. You don't need to run yours at full power, mine seems to like it so I stuck with that load.
105GR BY WEIGHT WILL EQUAL 150GR BY VOLUME OF BLACKTORN IS A MAX LOAD !!! DON'T EVER GET THE TWO MIXED UP!!!
