CUSTOMER TESTIMONIALS
Only Accurate Rifles
Many of us have heard that saying. That phrase may be further accented with the words matter or count; only these have any merit.
I have been shooting accurate rifles all of my shooting life. I stay in a mindset of demanding quarter-MOA or better from any rifle I shoot. I began a journey 12 years ago, falling in love with muzzleloading.
Once I started to learn smokeless muzzleloading and realized the accuracy available to those willing to embrace this style of rifle, I became addicted.
I have always been involved with the build process of any rifle, whether doing my own work or having a rifle put together. Through that experience, I came to value the expertise of master gun builders, especially those who are open to new ideas and who think outside the box.
Muzzleloading, in some sense, has never developed to its full potential. Many who love and practice it at the same time limit new design and innovation. Anyone who shoots and appreciates an accurate rifle must recognize all of the improvements made in centerfire rifles—new calibers, new bullets, new powders, and more.
John Nagel has helped me step into a whole new world of potential: in accuracy, in economics, and in enjoyment. Did I mention accuracy?
The two .30-caliber rifles that John put together for me—well, let's just say they outshoot any centerfire rifle I have ever shot. I am very excited about the sub-bores he is presenting to the American muzzleloading community.
I recommend his work, his advice, and his vision. There are not many people I can say that about today.
I'm looking forward to what he and others are doing to advance the future of muzzleloading.

CVA Paramount Prototype Build
This is a prototype build on a CVA Paramount action, #17 contour Brux .300/.308 barrel finished at 26" & topped off with a Fury PRS 5 port comp. muzzlebrake.
Factory trigger set down to 1.5lbs.
It has a one-off powder chamber based on 300WSM case, designed just for this build. Ballistic capabilities range from 30/06–300WSM with light to mid weight bullets.
Hankins HIS breech plug, ASG bolt nose, on a MDT XRS Chassis stock, Arken EP5 Gen II 7-35x56 scope on a EGW 20moa rail.
Custom load thru funnel & bullet starter. The finished weight is 16lb 4oz.
- 125g bullets at just under 3400fps
- 150g bullets between 3050–3150fps
Accuracy is match grade level (when the shooter does his part). My bench rest shooting skill level truly does not do this gun justice.
These are 200yd test groups shot while doing load development.

"Ordered a muzzle brake for my Ruger American Gen 2 in .308. The factory brake shot ok, but not great — this gun is most accurate with 168–175 gr bullets. The new Fury muzzle brake cut the recoil down to a much more enjoyable shooting experience with these grain bullets. Accuracy improved from a 2-inch group down to a 1-inch group using the same factory loads.
I then ordered an MDT stock from John and the group went to a ½-inch group using the same factory loads — with the combination of the new brake and stock. It's also a very comfortable gun to shoot now with the brake switched out."
