New StaBALL 6.5 Powder from Winchester — Temp Stable

Winchester ball spherical propellant powder temperature stable staBALL 6.5

Winchester has just introduced a new ball propellant, StaBALL 6.5, which it claims is very temp-stable. This means velocities and pressures should not vary greatly across a wide range of ambient temperatures. Winchester states: “StaBALL 6.5 is the world’s first temperature-insensitive Ball Powder, stable in extreme-hot or extreme-cold temperatures.” Winchester also claims StaBALL 6.5 can offer 30-200 fps greater velocities than other powders with similar burn rates. This new powder also has additives to reduce copper fouling. StaBALL 6.5’s burn rate and load density is good for popular cartridges such as .223 Rem, 6mm Creedmoor, 6.5×47 Lapua, 6.5 Creedmoor, and .270 Win. If StaBALL 6.5 can really deliver excellent metering, temp stability, more speed, AND less fouling — Winchester could really have a winner.

Metering Advantages of Ball Propellants
As there are existing very temp-stable extruded powders, such as Reloder 16 and H4350, what’s the big deal here? Well ball powders, with their small spherical granules, flow easily and meter well. This means ball powders can be thrown in manual powder measures with great precision. So StaBALL 6.5 could have advantages for hand-loaders using manual powder measures or progressive presses with mechanically-operated charge dispensers.

Winchester’s StaBALL 6.5 Product Description States:

StaBALL 6.5 is the world’s first temperature-insensitive BALL® Powder, stable in extreme-hot or -cold conditions. It provides optimal loading density in cartridges appropriate for the burn speed, which is ideal for 6mm Creedmoor, 6GT, 6.5 Creedmoor, 7MM-08, .270 Winchester, and many more.

Typical of a ball powder, precise metering contributes to improved velocity and pressure standard deviations, ingredients that are paramount to match grade accuracy!

This “environmentally green” propellant has copper fouling reducer additives, meaning longer durations of competition and field shooting without having to clean the bore. Precision accuracy throughout the match!

Velocity levels obtainable, depending on the cartridge, are 30-200 fps greater than other propellants in its class.

StaBALL 6.5 powder is available in 1 lb. and 8 lb. containers.

Sunday GunDay: German Centerfire Rifle with Rimfire Conversion

sauer 202 varmint rifle 22LR

Shoot Rimfire Ammo from your Centerfire Rifle

Wouldn’t it be cool if you could shoot .22 LR rimfire ammo from your regular hunting or tactical rifle? That would be ideal for low-cost training right? Well, this IS possible, provided you have a rifle that was designed with a .22 LR conversion in mind. One such firearm is the remarkable Sauer 202 from Germany. This impressive centerfire rifle is available with a factory-engineered .22 LR rimfire conversion. Read on to learn how Sauer’s cool .22 LR conversion works.

Sauer 202 Rifle: .308 Win/6.5×55 with .22 LR Conversion
Forum member “Tooms” sent us a report on his very special Sauer 202 with a .22 LR conversion kit. Sauer 202 rifles feature a “Quick-change barrel system”. The barrel is clamped into the receiver with crossbolts providing tension. This allows barrels to be swapped in a few minutes with simple tools.

Tooms, from Denmark, explains: “The rifle began as a Sauer 202 Avantgarde Gold in .308 Win. I have added a 6.5×55 match barrel, plus a wide flat-bottom match fore-arm with rail for handstop and bipod. The .22 LR system [originally] cost $1000.00 [including] barrel, bolt, magazine well assembly, and magazine. The barrel is attached by three cross-bolts and the magazine well assembly is attached by one screw that fits into the barrel.”

Using this “Quick-change system”, Tooms can easily remove his centerfire barrel and swap in a .22 LR barrel. Then he places the factory conversion kit into the magazine well. This kit provides a rimfire bolt, a fitted sleeve for the rimfire bolt, and a magazine housing. This is a full Sauer factory-designed system so it works flawlessly. With the bolt closed, you can see the “new” .22 LR chamber in the front section of the loading port. On the silver section of the bolt you can see the rimfire extractor on the side.

The .22 LR Conversion Really Works
The Sauer 202 Varmint rifle shoots very well with the .22 LR conversion, as the 50m target at right shows. Though quite expensive, the conversion kit essentially transforms your centerfire rifle into fully functional, mag-fed precision rimfire rifle. That makes the Sauer 202 much more versatile as a hunting platform. It also allows you to cross-train with inexpensive ammo. You don’t have to purchase another scope, trigger, or stock. And you enjoy the exact same stock fit and ergonomics whether you’re shooting centerfire or rimfire. In some countries where gun ownership is severely restricted, it may be easier, from a legal standpoint, to purchase a .22 LR conversion kit than to obtain a permit for a second rifle.

The Sauer 202 rifle line-up has been replaced by the Sauer 404 series which has much in common. To learn more about the complete line of Sauer rifles visit the J.P. Sauer USA website. You’ll also find more information on the primary J.P. Sauer & Sohn German website, www.Sauer.de. Though out of production, some Sauer 202s are still for sale at EuroOptic.com.

Mr. and Mrs. King Share a Martini — Mark III Variety

Here is gunsmith Richard King, with his updated Martini Mark III smallbore rifle.

This is the kind of family-friendly, “feel-good” story we like. A few years back, Texan Richard King created a rimfire benchrest rifle using a classic Martini Mark III smallbore action. He fitted the gun with a new flat, wide forearm and a new buttstock, allowing the gun to sit steady on the bags and track smoothly. The narrow action was also fitted with a cantilevered top rail to hold a high-magnification scope.

Here is Vicki King, with Martini Mark III and her trophy.

But here’s the best part. Back in 2014, Richard provided this updated classic to his wife Vicki, who proceeded to win a rimfire benchrest match (Vintage class) with the old Martini. Richard reports: “Here is my lovely wife with her High Overall Vintage trophy. That is a Martini Mark III that I re-stocked in walnut for 50-yard, .22-caliber benchrest matches. It’s great to have her shooting with me again.”

Bravo Richard — kudos to you AND to your lovely bride. It’s great to see a couple shooting together. It’s also great to see a classic rifle brought back to the winner’s circle with some inspired stock-work, new optics mount, and other smart upgrades. Old rifles never die… at least if they find their way to a great smith like Richard King.
