Need Data: S&B 30-06 Brass

[GermanS1]

I need a bit of help!

Most 30-06 brass weighs in the range of 190 to 200 grains, depending on the manufacturer and the lot. Load data is developed with that in mind and is pretty reliable.

This weekend, I found two,2) pieces of S&B,Sellier & Bellot) 30-06 brass at the range and took them home. To my amazement, they weigh 175 grains. That would really require a change in loads, but interestingly, might allow charges of 4831 with heavy bullets that I can't fit into normal brass. I max out on case capacity about 2 grains below what it would take to reach SAAMI max pressure using 4831, so this is potentially interesting.

My problem, of course, is that I only have those two pieces. If any of you have some S&B 30-06 brass, could you please weigh it and post your results? It would be best if it's weighed without a primer, but if you weigh with a primer just note that in your post. I'm not looking to buy any brass, just gatehring data. Thanks!

I wouldn't get too excited unfortunately. S&B brass is generally very poor. I bought a 100x in 8mm Mauser recently. The variation in primer pocket depth and tightness and overall length had to be seen to be believed.

I have 50 pieces of S&B brass for 54R. It works fine for a 1.5 MOA rifle and iron sights. That's the end of the story, you're going to chase your tail like crazy trying to make them shoot well in a sub MOA or better rifle.

Look at Norma brass, I've been told that you can get 64gr of RL22 in it, with my RP brass I'm really pushing it trying to get 62 in there.

I will weigh Lapua 30-06 brass this weekend an dlet you know on Monday

Thanks everyone! I did some water capacity testing and it's bigger inside but not as much as I might have expected. I'll do a chart and post it along with neck variance, etc.
