I read this email I received this morning and felt the need to share it with you.
Below is a copy and paste of the email text body. Enjoy!
REVOLUTIONARY NEW CARTRIDGE
7.7 MM TOMCAT
PATENTS APPROVED in 2023
We are happy to announce the issuance of our
patents (USPO #6679-321-44789F - #6760-4491-33984B) for the NEW 7.7mm TOMCAT long-range cartridge utilizing solid fuel propellant technology. This has been a 52-month project in collaboration with LAPUA, DUPONT POWDERS, FEDERAL
PRIMERS, and SWISS DEFENSE BULLET CORP.
A shoulder-fired, long-range sporting cartridge that
exceeds all past performance standards will soon be
available to the shooting public, as well as select
military units around the world.
While many consider the 7.7mm caliber to be the
optimal bore for mild-recoiling long-range work, there were several obstacles that needed to be overcome in order to produce a practical cartridge that lives up to the caliber’s potential.
DESIGN PARAMETERS
First, the cartridge had to be functional in a long
action with a magazine box of 3.800 inches.
Second, muzzle velocity needed to approximate
3600 FPS using a 200 grain bullet with a G-7 BC of
.490, while keeping recoil levels below 28 foot-lbs.
Enter SWISS DEFENSE BULLET CORP., which is
primarily a defense contractor for the European
market. We had difficulty getting them on board due
to the UKRAINIAN war and supply-chain difficulties.
Once contracts were signed and a hefty deposit was
paid, however, we were off and running.
The finished product was a 200-grain masterpiece of
gravity-defying, wind-bucking aerodynamics that
leaves one speechless. It features a 15-degree
rebated boattail design, a wasp-shaped straight
section (similar to the Herters design from decades
past), and a user-friendly tangent ogive.
Jacket material is a proprietary blend of molybdenum and cupro-nickel, which is Teflon 3Z infused (reducing friction, minimizing fouling, and adding roughly 100 fps. more velocity than a conventional copper jacket). The core is a proprietary blend of lead, molybdenum, and cobalt powder. This combination allowed us to achieve a perfect center of gravity on this 1.437-inch-long bullet.
Third, a case had to be designed so that barrel life
was decent, given the previously mentioned
performance standards. Test barrels have gone
3200 rounds; accuracy remains less than .5 MOA.
LAPUA was responsible for case development.
Again, we had delays due to the conflict in
UKRAINE. They were, however, able to keep delays within reason, given the overseas conflict. Case head
dimensions were .535, case OAL was 3.00 inches,
shoulder diameter was .490, shoulder angle 36
degrees, and a neck length of .410, which aids in
convergence angle efficiency and contributes to
longer barrel life.
Fourth, since traditional propellants were unable to
achieve these results, a suitable alternative had to
be found. This proved to be the most difficult task of
all. With a grant from a US defense contractor (whom I can't disclose), we joined efforts with DUPONT to
produce a solid Duplex-Based propellant ignited by a
smaller charge of proprietary powder. The ratio of
burn rates in the solid propellant was erratic and
caused extreme pressures in load development.
HP WHITE laboratories did the initial testing (we
destroyed several actions in the process). However,
once the precise ratios of the different burn rates
were established, we were able to achieve a MV of
3580-3620 FPS with a 200-grain bullet. Pressure
testing was rated at 62,000 PSI from a 26-inch
barrel.
I am pleased to announce that LOADED ammunition
will be produced by LAPUA and available through
numerous wholesale suppliers in the US.
Ammunition cost is expected around $85-90.00 for a
box of 25 cartridges.
I have licensed JGS, CLYMER, and HUGH
HENRIKSEN to produce chambering reamers for
licensed gunsmiths around the country.
Barrels will require a 7.3-inch twist; to obtain
specified velocities we recommend a barrel length of
at least 26 inches.
If you are looking for the ULTIMATE long-range
cartridge look no further than the 7.7mm TOMCAT.
Ballistic DATA:
Muzzle velocity 3600 FPS;
G-7 BC .490; Elev. 1000' Temp. 59 degrees, Humidity 50% utilizing a 200yd. zero.
Drop at 1000 yds. 12.5 MOA; Wind Drift 2.25 MOA;
This amazing combination produces 1340 Foot-lbs. of energy at 1400 yds.
Performance testing on game animals will be done this August in South Africa. I've purchased 200 cull permits for testing and evaluation. Willing participants will include, kudu, eland, wildebeest, gemsbuck, zebra, and waterbuck.
I expect the first container of ammunition to hit US
shores around November 5th. We are limiting
purchases to 500 rounds per customer to gain as
large of a market share as possible.
Stay tuned for more details via the NEWSLETTER.
Ron Spomer of SPOMER OUTDOORS is expected
to do a YOUTUBE video of this new cartridge as
soon as the snow melts at his off-grid Hacienda in Malad, Idaho. (sometime in late June early July)
In the meantime enjoy our April Fools Day spoof from Hollands Shooters Supply.
Be safe, stay healthy, and shoot straight."
I admit it, it had me until as I was reading the dollar signs started to glow.
Good To Still Be Gotten On April Fool's Day!
