Got Powder? Here Are Sources for Many Popular Propellants

reloading Powder Sale Midsouth discount

It’s July 4th, that means fireworks displays. What better time to order up some gunpowder? We’re pleased to report that Midsouth Shooters Supply has received some big shipments from the major powder makers. In stock now at Midsouth are many of the most popular accuracy powders, including: Hodgdon H4350, Hodgdon 4831/4831SC, IMR 4166, Vihtavuori N133, Accurate LT30 and LT32, Norma 203B, CFE223 and many more. Powder Valley also has Hodgdon H4350 right now.

Meanwhile at Precision Reloading you will find Alliant Reloder 16, Reloder 23, Reloder 17, IMR 4166, IMR 8208 XBR, Vihtavuori N133, Accurate LT30 and LT32, Norma 203B, and many more.

H4350 and Reloder 16 are superb, temp-stable powders for medium-sized cartridges. Reloder 23 is a slower version of RL16 that works great in magnum cartridges. LT30 is great for the 30BR, CFE 223 is excellent for Service Rifle shooters, and VV N133 is a top choice for the 6PPC. Norma 203B (nearly identical to Reloder 15) works well in the 6mmBR, 6BRA and Dasher. And Hodgdon H4831SC is an excellent choice for the .284 Winchester and 7mm WSM.

Sorry we could not find Hodgdon Varget at these two vendors. However, Bruno Shooters Supply does have Varget in stock today in both 1-lb and 8-lb sizes. Varget fans may also want to try IMR 8208 XBR. It has a slightly faster burn rate, but our tests found it worked very well in the .308 Win with medium-weight bullets, offering excellent accuracy and good velocity.

All these popular Powders (and many more) are in stock:

New AR-Comp Powder Starts Shipping This Week

AR-Comp Alliant PowderAlliant is introducing a new extruded powder, AR-Comp. AR-Comp is an advanced re-formulation of Reloder 15, a double-base Bofors powder. There are changes to internal and external chemistry to provide much better pressure/velocity stability across a wide range of temperatures. The main difference between AR-Comp and Reloder 15, is the AR-Comp has a slightly faster burn rate, and AR-Comp is much LESS Sensitive to temperature changes. AR-Comp is a small-kernel, double-base extruded powder like Reloder 15, so it will continue to meter just like Reloder 15. The load density should be the same as Reloder 15.

AR-Comp should be at Grafs.com in a Couple Weeks
Here’s the good news — Alliant will start shipping AR-Comp to Grafs.com later this week. Dick Quesenberry, Alliant Powder Product Manager, told us: “I just received the AR-Comp packaging labels and we hope to send off the first shipments to Grafs this week.” With transit time, expect the powder to be available from Grafs.com by the second week of June. You can go ahead and place advance orders for 1-lb and 8-lb containers of AR-Comp on the Grafs.com website.

AR-Comp Offers Uniform Velocities over a Wide Temp Range
Tests were done with .223 Rem and .308 Win ammo, loaded with AR-Comp and maintained at temps from -20° F to +160° F in a controlled test center. The ammo itself was heated or cooled to targeted temps before testing. Across that entire range of temperature, -20° F to +160° F, the ammo loaded with AR-Comp showed a variation of only 20 fps in muzzle velocity. The primary bullet type tested was a 77gr .224 bullet and the secondary was a 175gr .308 bullet.

Burn Rate Like Varget
Though this is a reformulation of Reloder 15, the burn rate of AR-Comp is slightly faster than Reloder 15. Alliant told us: “Reloder 15 is slightly slower, in burn rate, than Varget. The new AR-Comp, with the enhancements, ended up slightly faster than Reloder 15, so it is now very close to Varget in burn rate”. This is the result of the “tuning” of the powder to be much less temp-sensitive.

AR-Comp First in Series of New Alliant Temp-Stable Powders
AR-Comp will be the first in a series of “new generation” temp-stable powders from Alliant. Quesenberry noted: “Our goal was to provide a powder that offers stable pressures in all temperatures. Shooters want to be able to stay with the same load in winter and in summer, in cold or in hot conditions.” Quesenberry added: “We’ve been working on this quite a while. AR-Comp is the first example and we hope to extend this to other rifle powders. It’s a tough job. You have to balance the performance carefully. We worked very hard to do just that and we think shooters will be impressed with the results.”

Reloder 15 Will Stay in Production
Fans of Alliant’s Reloder 15 don’t need to worry. Alliant will keep Reloder 15 in production. “We don’t drop powder lines”, said Quesenberry.

New AR-Comp Powder from Alliant — Details Revealed

AR-Comp Alliant PowderHere’s the latest info on Alliant’s new AR-Comp powder. We had a chance to talk with Dick Quesenberry of Alliant, who revealed more details about this new propellant. First, Dick explained that AR-Comp is an advanced re-formulation of Reloder 15, a double-base Bofors powder. There are changes to internal and external chemistry to provide much better pressure/velocity stability across a wide range of temperatures.

AR-Comp Offers Uniform Velocities over a Wide Temp Range
Tests were done with .223 Rem and .308 Win ammo, loaded with AR-Comp and maintained at temps from -20° F to +160° F in a controlled test center. The ammo itself was heated or cooled to targeted temps before testing.

This is the result of the “tuning” of the powder to be much less temp-sensitive.

Meters Like Reloder 15: AR-Comp is a small-kernel, double-base extruded powder like Reloder 15, so it will continue to meter just like Reloder 15. The load density should be the same as Reloder 15.

Loaded Ammo: We asked if any manufacturer will be using AR-Comp in loaded ammo. Dick told us that he is “not allowed to release that information at this time”. Draw your own conclusions, but remember that Alliant is owned by ATK, which makes Federal rifle ammo.

Available in Summer 2011: Allliant hopes to ship AR-Comp in “June or July” of 2011, provided the DOT Classification process moves at a normal schedule. The powder is ready to go, Alliant is just waiting on the DOT to provide shipping authorization.

Reloder 15 Will Stay in Production: Fans of Alliant’s Reloder 15 don’t need to worry. Alliant will keep Reloder 15 in production. “We don’t drop powder lines”, said Quesenberry.

AR-Comp First in Series of New Alliant Temp-Stable Powders
Alliant has been working on AR-Comp for quite some time. This represents a major evolution for Alliant’s powder line. AR-Comp will be the first in a series of “new generation” temp-stable powders from Alliant. Quesenberry noted: “Our goal was to provide a powder that offers stable pressures in all temperatures. Shooters want to be able to stay with the same load in winter and in summer, in cold or in hot conditions.”

Quesenberry added: “We’ve been working on this quite a while. AR-Comp is the first example and we hope to extend this to other rifle powders. It’s a tough job. You have to balance the performance carefully. If you tweak it one way, say to improve the low temp performance, you lose something at the upper end. If you tweak it for the top end, you loose something at the bottom. You have to hit that balance. We worked very hard to do just that and we think shooters will be impressed with the results.”

New AR-Comp Powder from Alliant — Swedish Varget?

Alliant AR-Comp Powder SwedenHere’s important news for handloaders. Alliant Powder has introduced a new medium-burn-rate powder: AR-Comp™. This new powder was developed specifically for AR-style rifles. Alliant says that AR-Comp powder is “ideally suited for heavy .223 and .308 match bullets”. We presume, from that description, that the powder will have a burn rate similar to Varget. The AR-Comp powder, produced in Sweden by Bofors Nobel, is an enhanced temp-insensitive reformulation of Reloder 15. The burn rate is slightly faster than Reloder 15, according to Alliant.

Alliant Claims AR-Comp is NOT Temp-Sensitive
We have limited information about AR-Comp, and we have not yet been supplied with a test sample. We have confirmed is a double-base extruded powder, and is an upgraded version of the Reloder 15 formulation. Alliant claims the powder meters very well and delivers “consistent pressures and velocities across temperature extremes”. This new powder is supposed to be very uniform from lot to lot. That would be great — if it is true — but only time will tell.

We will try to get a sample of AR-Comp soon and test it in both .223 Rem and .308 Win rifles. We suspect, if AR-Comp suits both the .223 Rem and .308 Win, it should work well in the 6mmBR and 6.5×47 Lapua cartridges as well. Stay tuned — we hope to have more info next week. AR-Comp should be hitting the market in June or July, 2011, provided DOT Classification goes smoothly. It will be offered in both one-pound (#150664) and 8-lb (#150665) containers.
