I mentioned in a previous thread that I ran across Go West Trading Brass. I was looking for hands-on info., but didn't come up with anything concrete. So, I bought some 338LM. It was $1.20/ea plus shipping. ( $1.35/ea to my door ) All I have in empty Lapua Mfr'd cases are 20/pcs of once fired. They are not from the same Lot. They were wet tumbled with pins to remove any residue that could impact their true weight. Also, I have not ever handled virgin Lapua Brass. All of mine has come from firing loaded ammo that I purchased. That being said, I pulled 20/pcs of the GWT to compare weight, flash holes, primer pockets etc. The GWT came in trimmed to length. They were not deburred or tumbled after trimming. Trim Lengths: 2.715 -to- 2.718 (1/pc out of 20) Measured with Mitutoyo Digital Caliper. The flash holes did not have any burrs. The GWT weighs an average of 9.07/gr less than the Lapua. The Numbers... (20/pc Sample Size) Weighed with Dillon Digital Scale GWT: Average weight of 318.10/gr Heaviest: 320.5 Lightest: 316.3 Diff: 4.2/gr Lapua: Average weight of 327.17/gr Heaviest: 329.6 Lightest: 325.3 Diff: 4.3/gr I hope that this info. is helpful. Thanks for looking. If someone really really really wants to see the individual case weights, let me know. I'll see about getting them typed in.
