Gunwerks Brass (100 Count)
Sold in quantities of 100. Premium reloading brass engineered by Gunwerks. Designed as the perfect brass for precision shooters, this cartridge brass features extreme consistency lot to lot and extremely tight tolerances. Optimized case walls and primer pockets afford high brass life for maximum number of reloads possible. Uniform flash holes provide consistent ignition and low extreme spreads. We load our own Gunwerks ammunition with the same ammo because we know it meets our high standards where everything else falls short.
Extreme consistency piece to piece and lot to lot
Consistent weight & volume to reduce velocity spreads
Minimal neck runout for superior precision
Optimized metallurgy and dimensions to maximize case life
Clean case head design for easy pressure sign identification
All brass sizes feature large rifle primer pockets
Includes 100 round reusable, zippered pouch
Our brass is engineered with thicker walls than our competitors for extended case life, meaning more reloads. You may need to reduce powder charges to maintain desired pressures.
I was very pleased to see the Gunwerks box sitting on the front porch the other day. I had been patiently awaiting the arrival of their new 6.5 Creedmoor brass to try out. Upon opening it, I was impressed, noticing it had been annnealed. I took 50 of the 100 and measured the COAL, neck thickness and weights. This new brass is very impressive and very uniform with all three measurements. Neck sizing them and seating primers, the pockets are nice and tight as well. I loaded 6 different rounds (seating depth all the same) loaded with h4350, Hornady 143gr eld-x, CCI br2 primers and loaded those 6 charges at .2gr increments. At the shooting range I chronographed with my Magnetospeed with an impressive SD of 4fps, ES of 10, and MV of 2,757 fps (22” Xcaliber 1:8) groups at 100yd were awesome. Max spread was .565” and best group shot a .206”. I would recommend this brass to any shooter/reloader wanting tighter results with their shooting. I will definitely be purchasing more and hope to see a lot more of a selection to choose from. Amazing job, Gunwerks!
I have NEVER seen anything with consistency like this
I’m pretty damn picky about my brass, like most shooters are... but I have NEVER seen anything with consistency like this... I received my Gunwerks 300wm brass and the case it comes in... not going to lie, it’s a pretty sexy case I now have plans for. The first thing I did was grab a handful and look them over for any obvious flaws. None. Now for everything below, all of the tools are calibrated to ANSI/ASME standards with NIST traceable equipment. I randomly selected 10pcs for an adequate sample. First test was to measure neck wall thickness in three places on each piece of brass. This was performed using a Mitutoyo tube micrometer with 0.0001” resolution. Completed. Min thickness was 0.0131” and Max was 0.0140”, difference was 0.0009”. 0.0135 ± 0.00045”. When the difference is under 0.001” I can be pretty pleased with that. Second test, which I really wasn’t too concerned about since it’ll change (but is worth looking at to understand manufacturing standards) is the case OAL. This was performed on a Starrett digital caliper with 0.0005” resolution. Min was 2.6100”, Max was 2.6115”, difference of 0.0015”. 2.6107 ± 0.0007”. SAAMI spec is min 2.600 to max 2.620. So they were right over half of spec. Next was weight. This was performed on a freshly calibrated A&D FX-120i lab balance. I expected to see some serious difference here. But I was wrong. On the same ten pieces, they were weighed and recorded in a temperature controlled room with a cover over the draft walls. The balance is capable of reading to 0.01gr or 0.001g, even though grams are more accurate, I chose grains because most shooters would be familiar with that measurement. Min was 248.40gr, Max was 249.92gr, difference is 1.52gr, average was 249.10gr ± 0.76gr. I gotta hand it to them... when Gunwerks says words like “PREMIUM”, “CONSISTENT” and state “Extremely Tight Tolerances”... the F**king mean it. Did I mention that it comes annealed? I haven’t used any of their products before... but I do know where I’ll be getting my brass from now on.
