  1. For a quick and cheap trigger improvement on the Scorpion buy and install an HBI reduced tension trigger spring for it. This will provide you with a surprisingly large improvement in the trigger weight. For a really first rate trigger job (but much more expensive) you could send your trigger group to CZ custom. I love my scorpion but am switching to a JP for the reduced recoil and dot movement.
  2. Which magwell would you recommend for a GMR-15 build for USPSA? I currently have a rifle on order and specified the TF Fattie magwell option. However, a friend of mine told me the Techwell option is superior. Any advice welcome. Thanks in advance.
  3. I had the crushed primer problem with WMA 9mm brass. I had lots of problems as virtually all of my 9mm brass is WMA. I would have 30 or so per 100 rounds loaded turn out with crushed primers. I ended up taking my machine to Mark 7 for them to work on in their shop (I live 1.5 hours away from them). They fixed it and I haven't had a single problem with it since (8-10K rounds loaded). I wish I knew what they did to tell you but I can't remember what they told me they replaced. It worked, though.
  4. I believe anyone who buys a revolutionary design in an established industry should expect to have to work out minor flaws. Each time a customer raises a new problem the company will learn and address it either in their manufacturing process or in a change to the design. With each problem the equipment will improve. I bought one of the first 25 machines that were sold to dealers. I had a primer problem with my machine that took Mark 7 and me a while to figure out and fix. My machine runs perfectly now. Well worth the initial frustration.
  5. I had a similar problem that was linked to a nick in the whole the primer rides in as the bar advances. It caused the primers to, occasionally, get flipped sideways. When the primer bar slid forward to the primer would get crushed and hang the mechanism up. The solution was to disassemble the primer bar and sand the nick out of the bar. It has worked perfectly ever since.
  6. I watched a video of Jerry Michelec using a cement mixer to wet tumble his brass. He dumped a full 5 gal bucket of brass in at a time. Tumbled for 2 hours with liquid soap. I looked at a cement mixer in Harbor Freight and it was close tot he same price as the FA tumbler. If I had more room that is the way I'd process my brass. I wet tumble now and it gets the brass perfectly clean. Lay them out on a towel to dry for a couple of days, spray with One Shot and pour into WalMart half gal plastic jugs for storage until needed.
  7. I, almost exclusively, use military 9mm brass for reloading. My machine was one of the very first Evolutions sold; #21 I believe. Initially I had a problem with properly seating the primers in WCC head stamped military 9mm ball casings. I had the folks at Mark 7 look at my press and they were able to easily fix it. The press has run perfectly since then. Your press should process military 9mm brass with no problem. If you do have a problem the tech support folks at Mark 7 can help you get it to 100%. They are very helpful.
  8. I agree with Eric85. I had a lot of frustration with mine when I first started using it. Cleaning up and flashing around the edges and sanding the hole with very fine sandpaper fixed 90% of the problem. I also drilled a small hole in the plastic cover directly over the hole so that when I do get one that sticks I can take a toothpick and nudge it straight. you just have to barely touch it to line it up and then it falls right in. Usually I only get one that I have to nudge every 200-300 primers. I use a toothpick because I don't want to touch the anvil with any metal, just in case. There are several other tweaks you can to do improve it even more but I find that mine works so well I wouldn't take an RF100 if it was given to me now.
  9. I have been holding off making any comment on this thread until an initial issue I had with my Mark 7 evolution was resolved. Initially I had an issue with the priming station seating on a specific head stamp of brass. I get virtually all of my brass from a military range. They actually love giving it to me to reload because it is less hassle for them to dispose of it. The head stamp is WCC and it is crimped. I switched from a Dillon 650 so that I could get a swaging station. I was going to just upgrade to a 1050 but a friend of mine told me I should check out this new press from Mark 7. I did and saw that it was so much better engineered than the Dillon I had to have it. So, I bought a manual Evolution. As I said, when I got it and put it together everything was great except that half of the cases ended up with high or mangled primers. I worked with it on my own and put in several trouble tickets and talked to technicians at Mark 7 trying to fix the problem. They were supper helpful, friendly and supportive. Once on a Saturday night I put in a trouble ticket online at about 7:30PM and get a call from one of the technicians about 10 minutes later. He stayed on the phone with me for 45 minutes on a Saturday night trying to solve the problem. Finally we agreed the best thing to do was for me to simply ship the press back to them to fix it once and for all. Since I live only 2 hours away I drove it to them and dropped it off. after about a week I called to see how it was going and was told it would be finished and ready for pick up or shipment back to me the next day. I drove down to Mark 7 the next Monday and was met by Jay, the owner, Misty, Head of Tech Support, and Dan, the tech I had been working with. They all were great. They took me back to my press which they had mounted on a Revolution base plate and Jay walked me through all the things they had changed and upgraded on my machine. They had done a total rebuild of the press from the bottom up and tested every single item to ensure it was correct and properly functioning. in order to deal with the military brass properly they had to make a few modification to ensure reliable functioning of the priming unit. I had given them about 200 of the WCC head stamped cases along with powder, primers and the bullets I use an they had loaded all of them along with some of their own cases and different primers to ensure the press worked on everything. Misty handed me paperwork that reset my warrantee to that day and said if I get the press back to them after I run about 40-50K rounds through it they would do another complete rebuild and inspection to see how everything is holding up. In addition to all this they let me take the Revolution base in case I wanted to add an auto drive or primer collator in the future so it would mount easily. I can't say enough about the SUPER support I received from Mark 7. They went way above and beyond to make a great product better for me and ensure I was pleased with my purchase. BTW, the press operates PERFECTLY now. I am so very pleased I can't enough good. As to the question of is it worth the money I will say it is worth every penny if you want the best there is. If you are the type of person that buys power tools from Harbor Freight and don't mind the noise, vibration, and short lifespan of the tool you may not want a Mark 7. If you are the type of person that wants the best and you are willing to pay for a lifetime of worry free enjoyable use then you will only sweat the cost once. You will enjoy the operation each time you use a Mark 7. Also, in case anyone is wondering, I am not affiliated with Mark 7 in any way and have not received any discount or favor from them for this input. I am just an average retail consumer who likes to give credit where it is due. My woodworking tools are from Festool, Felder Hammer, and Sawstop. I only buy the best. That is why I am happy with the price of Mark 7 reloading equipment and am a loyal customer.
  10. BTW, the primer collator is available for the EVO now. I talked to Dan at Mark 7 and he told me they had scrubbed plans to build a separate primer collator for the time being and are offering the same one that is on the revolution. It is about a $2100 upgrade. I don't see that in my future at that price. I just don't shoot enough to justify it. I currently use a Vibraprime and load up 10 tubes in a session. That gives me 1000 rounds worth of ammo in a reloading session. That keeps me in bullets for 3 weeks or more, depending on the season. I can buy a lot of toys for my other hobbies with the 21 bills I would pay for the collator.
  11. So as to keep the technical thread as clean as possible I will make my comment here. Thank you very much. I am certain the Mark 7 Evolution will get any glitches it currently has worked out and will represent the gold standard for consumer reloading for many years to come. I feel fortunate that I was able to get one of the first units, at a very discounted price point from the current offering. even at the current price point the quality of materials,workmanship, and versatility of the press is amazing. I would advise anyone who is on the fence about buying one to go ahead and make the purchase now. Even at the current price point I believe Mark 7 will have all the business they can handle.
  12. The cost of an item isn't always an indication of the complexity of the device or the processes or materials required to make it. Demand, available alternatives, original development cost recovery, size of the market all play into pricing. Think about drugs. Something that cost pennies may sell for several hundred dollars a pill. Coffee from Starbucks also comes to mind. One thing is for sure. if the market is large enough for multiple suppliers competition will ultimately drive down the price to its lowest possible sustainable level.
  13. When I received my EVO (manual) I had a missing part from the bullet feeder. I called and they cannibalized one on the shelf to get me my part. I also had a problem with the primer seating. I called after hours one night and a tech answered the phone and worked with me over the phone while I tried different things to get the problem resolved. I have had super CS support from Mark 7 and I consider it every bit as good, if not better, than what I previously had with my Dillon machine.
  14. I drilled a small hole in the plastic tip directly on top of where the primers slip into the tube. I keep a wooden toothpick handy so if a primer ever gets stuck sideways I can gently tweak it back into position to clear the jam. I wouldn't want to use anything metal.
