Beat Varget? It couldn’t be done. After all, THAT powder has got just about the most fanatical following in the industry.
It was a tall order that we placed on our Shooters World designers and quality assurance folks. Much discussion. Much head nodding, and head shaking, finger waving, white-board writing, graphs, arrows, derivatives and integrals, shoulder shrugging…and time. Much, much time. Trial after trial. Improvement after improvement. That was back in 2014 that we made the first appeal for this powder, this technology, and this burn speed.
We had tasked our manufacturer with the creation of a propellant that would out-perform Varget®. We wanted the same burn speed. We wanted the same density. We wanted easier and more consistent volumetric charging. But most importantly, we wanted superior ignition, and superior temperature insensitivity. We wanted it more accurate.
Since receiving the early samples of this propellant, and our first production lot, I have made it my A-number-one objective to proof this propellant. If my personal name was to be associated with it, it had to be very, very right.
After what seemed like an eternity, made even longer by my eagerness to get my hands on this new propellant, I have run it through many cartridges. I have charged with it through numerous meters. I have run it at temperatures ranging from -65F to +165F. I have shot it for accuracy. Repeatedly, I have compared it directly to Varget®.
As I reviewed the published charge weights, velocities, and pressures of Precision and compared them to Varget®, there’s very similar performance. When I was directly comparing charge-for-charge, and load-length-to-load length, I found in numerous cartridges and bullet combinations that my ballistic results were within 25 fps of the published Varget® data. Same charge weight, similar pressure. Same charge weight, similar loading density.
That said, keep in mind that I’m an accuracy nut, and I’m not exactly one to follow the herd. I’m an Olympic shooter, and an Internal Ballistic Engineer. I don’t arbitrarily assign a cartridge overall length. If the goal is accuracy, I purposefully set each and every one.
And as you may know, cartridge overall length (COAL) can and does affect the pressure/charge weight/velocity relationship. It also affects accuracy, efficiency, and barrel life. So, I take it seriously.
One of the advantages of handloading is being able to define your own load length. Knowing this, we further assist the handloader by publishing resultant pressures, velocities, and charge weights, when a specific projectile is positioned very close to the optimal location. Why? Because it’s all about hitting the target. FIRST you’ve got to hit the target, only then you should concern yourself with velocity.
Our load lengths are purposeful. And because of that, as well the inherent (small, but significant) variations in testing results from barrel-to-barrel, our data is not an exact match to that data published by other companies. But rest assured, if you’ve got a SAAMI or NATO chamber, know that Shooters World reloading data is optimized for your chamber and/or your system. If you’ve got a European CIP chamber, know that we also support those chambers and cartridges with European load data too!
Some folks believe that “Temperature Sensitivity” is something that you sprinkle into propellant as it’s being made, like an ingredient. I’m here to tell you, there ain’t no “throw a couple scoops of Insensitivity-Pixie-Dust into the powder vat,” any more than there’s laces for your trigger shoe. Nope. Temperature insensitivity has everything to do with how the propellant burns before the system hits max pressure. That’s it. That’s the secret. And there’s no “secret sauce” that is going to change that fundamental principle.
In validating Precision against Varget®, we used this fundamental principle in our testing. We took both Varget® and Precision out of their intended “happy place” and forced them to perform in numerous environments where they should fail. These methodologies will remain proprietary to Shooters World. But please understand that our boastful claims of superior temperature insensitivity and velocity standard deviation are founded on real-world results in overly demanding environments.
And it’s this combination of know-how, propellant technology, and shooter-to-shooter empathy that makes us different. We shoot. And we know shooting. All the load building work we do is tedious, but through virtuous and diligent work, we hope you find our products, services, and data the best.

It is good to know there is a powder comparable to Varget. I would like to try the Shooters World powders, but I haven’t seen a manual yet. Once that is available I will get some of it.
Downloadable from website…
Your graph suggests that the powder sensitivity is identical between 50 and 125. Your powder has an advantage at 165 degrees but no one shoots at 165 degrees, therefore you have manufactured a powder that parallels target but at a lower velocity. No sour grapes here as I don’t use target.
Chamber temp in longer strings of fire can make the upper temp range more important due to the ammo heating while in the chamber.
COST and availability??
well, price is about the same $170 for 8 pounds at Midsouth supply.
So, how long has “LOVEX” been in business? (the powder producers)
Lovex has been in business since the 1920’s. As far as price, Midsouth is waiving the hazmat fee with a purchase of 4# or more of these powders.
Precision will be anywhere from $3-$5 less per pound. But will be available when you need it.
One of the most typical and persistent complaints I hear
about Varget is the variable from one production date to
another. My personal experience with this problem has been
2 full grains of powder. In other words, lets say my load was
46.0 grains of Varget for a specific weight/design/manufacture.
Opening a “new” 8lb container and bingo, pressures signs
everywhere. Had to reduce two full grains of the “new” batch
to produce the previous level of accuracy and muzzle velocity.
With the introduction of the new IMR powders, I’ve switched
where I can get close to the velocity, and usually improve on the accuracy.
You simply have to get much more reloading data available for these powders over a wider range of cartridges and bullet weights. Until then they will languish and that would be a shame.
Very good marketing advertisement. All hype and no technical data, no comparison of standard deviation, no comparison of group sizes, no mention of accuracy vs accuracy. There is nothing in this marketing sheet to suggest Shooters World actually outperforms Varget. Is that information to follow?
Yes, in part 2 and 3.
Any plans to offer/carry the SW4350 for sale?
Shooters World hopes to release SW4350 late June.
I really don’t understand the exuberance over varget. RE 16 and H4350 seem to give superior accuracy and velocities without the pressures in mid-size cartridges (6.5CM) while H4895 consistently out perform varget in .223 heavy bullets.
If it gives similar velocities as Varget; keep it!!!!!!!
Hello, Shooters World hopes to have enough data to release
SW4350 by the end of June.
I guess I’m missing something in this article! The graph shows the new powder as “close” to Varget! The article also says the price is about the same! Why would I buy something “close, but not as good” if they’re both the same price?
Here’s your load data.
Good stuff!! As a retired range instructor, I am using a few different ones; love all their results and COST!! The *VARMINT* powder in .223 has super velocities while maintaining accuracy! Up to the point of “soft point” varmint loads, burn up, needing to use ballistic tips to handle the speed! Grouping 1 1/2″ at 200 yards, OFF A BI-POD! Enjoy!!
It’s TACTICAL, NOT VARMINT!!!
HI Ken, I could use a good combination bullet & powder for my M700, 25-06 w/K&P barrel. I also will purchase one mere case of Tenex, before I give it up.Any clues to a lot number ? Jim Westgate is still shooting benchrest. I spend 3 months each winter near him in Lillian Al. Still a member at Ames. Chuck Cannon
Hi Chuck! So glad to hear you’re well! I hear you about the .25-06. That’ll be one of our next test barrels.
I have not seen any load data for the 25-06.
This is a great deer round as is the .257 Roberts .
Is more data to come.
