    Shooting The FX Impact MKII

    FX Impact - Episode 11 - Update When I started this thread, the FX Impact MKII was the hot ticket; a few short months later, it’s obsolete. Nonetheless, it’s all I got, so I keep testing. Maybe I’ll have some breakthrough discovery – not likely – but possible. Here’s what I have so far...

    Shooting The FX Impact MKII

    Hi, Thanks for the suggestion. The two bottle adapter looks to be a very useful option but its a bit spendy for me. The extra 480 cc FX bottle is $299 alone. Jan

    Shooting The FX Impact MKII

    Hi Pedro, Thanks for the confirmation. The comfort window for my FX Mk 2 seems to be regulated pressure of 120 Bar and bottle pressure of 150 Bar or less which seriously limits the number of shots per fill. Perhaps one of these days I'll buy an external regulator and tether the rifle to a...

    FX Impact - Episode 10 - Regulator(s) Hi, I've come across an odd phenomenon. Please take a look at the attached NF50 target and check out the difference in vertical dispersion between the first 8 shots and all the remaining shots. Beginning with shot No. 9, vertical dispersion is very good...

    Shooting The FX Impact MKII

    Hi, Lee used to make custom push through dies at a very reasonable price. I just checked and it seems that Lee is out of stock on almost all of the regular sizes and doesn't appear to be taking custom orders. NOE makes .221 push through sizers but the cost is significant. I don't recommend...

    FX Impact - Installment 9 - More Hammer Seat Blues Good morning, I had another issue with the hammer seat backing off of the valve rod despite the use of blue locktite. I checked other airgun websites and it appears this is a recurring problem with the Impact. So, if you have an Impact and...

    FX Impact - Installment 8 - Final Chapter? Hi, I'm out of ideas for testing (improving) my FX Impact. It's been a interesting experince but I think I've hit the limits for a factory gun. So, to wind things up, here are two pictures of my bench set-up. The AR-style grip is gone; replaced by...

    FX Impact Installment 7 - Good News For a Change Things are looking up. I raised the regulated pressure to 120 bar and adjusted the trigger pre-load and the Valve Adjustment to get 908 fps average. This was not one adjustment but the end result of a whole bunch of intermediate adjustments...

    Cleaning and Lube I've tried cleaning and lubing but not skirt forming. I've washed the pellets with a very dilute solution of Dawn dish soap. After drying overnight, the pellets were then: Left clean, or Lubed with a very light coating of Imperial Sizing Wax, or Lubed with RWS chamber...

    Shooting The FX Impact MKII

    FX IMapct - Installment 6 I've been otherwise occupied so there hasn't been much time to experiment with the FX Impact. So far, the rifle consistently shoots the National 50 target in the mid 240's (8 to 14 x-count) with JSB 25.39 Redesigned Monster pellets at 860 fps. The main issue the...

    Shooting The FX Impact MKII

    Good Customer Service My first experience with FX customer service was a happy one. Customer service picked up on my first call. I was immediately connected to a tech who diagnosed the problem and told me how to fix it. It turns out that the hammer seat was installed at the factory without...

    Shooting The FX Impact MKII

    Bummer The three month old FX Impact died today. I was shooting a National Fifty Target using 15.89 gr pellets at 980 fps - not a particularly hot load. After about 30 shots, the next shot dropped to 850 fps. The following shot went to 760 fps and then it just went "click." There are no...

    Shooting The FX Impact MKII

    Hi Joe, Good luck to the other FX Impact shooter. If his rifle is like mine, the factory regulator setting is 85 bar and the hammer spring preload is set to zero. If he hasn't already done so, he might try upping the regulator pressure to 110 bar and then increasing hammer spring preload...

    Shooting The FX Impact MKII

    FX IMapct - Installment 5 Mike sent me a practice National Fifty target in PDF. I made a .350 plug for pellet scoring. Attached is a National Fifty target I shot this morning. I think that the NF target combined with the .350 plug accomplishes Mike's objectives because it shows that a...

    Shooting The FX Impact MKII

    FX Impact - Installment 4 This isn't much of an installment - more like a "lack of progress" report. The barrel supplied with my rifle is a certified lead-mine. I've tried a variety of pellets and slugs - both lubed and not lubed, cleaned and not cleaned - all shot over a wide band of muzzle...

    FX Impact Installment Three This is a short one. I was testing JSB "Redesigned" 25.39 grain pellets and achieving some accuracy on IR 50-50 targets at 890 fps - approximately 44 FPe. Exteme spreads were 11 fps with SD's of 3. So far, so good. After a few targets, the extreme spreads...

    Shooting The FX Impact MKII

    To answer Tony's question, no. I'm reasonably sure that this barrel system is unique to FX air rifles. The FX barrel liners are also unique inasmuch as the rifling is pressed into the liner from the outside in. This is a bit hard to describe so I'll try to attach a picture of several Superior...

    FX Impact - Installment Two This installment speaks to one of the more interesting features of the FX Impact – the barrel system. The Impact does not utilize a traditional barrel. Instead, the system starts with a lightweight, rifled barrel liner. This barrel liner is then installed inside a...

    Shooting The FX Impact MKII

    In a previous thread, I proposed to test a new FX Impact MKII to see if it could be made competitive in ARA Unlimited competition. Initial results indicate that attaining this result falls somewhere between “not bloody likely” and “when Hell freezes over.” That said, this is my first air...

    Few Questions

    Entry Level Hi, This is not a product endorsement. If you just want to give air gunning a try, buy something like the Diana Stormrider in .177, an Air Venturi hand pump, and a few tins of pellets. Add your own scope and rings and your good to go for less than $500.00. Things get more...
