308 Win

[308 win]

I'm changing over from using Winchester brass to Lapua in my .308. Winchester brass has been unavailable the last two years and I was lucky to get Lapua. My load is 47 grains of Varget (compressed) under a Barnes 150 ttsx and Winchester large rifle primer. Any concerns going with Lapua brass?

I'd drop that load down some and work back up. Lapua brass has less capacity than Winchester so you may find pressure issues going from Winchester to Lapua.

Definitely drop back on the powder charge when going from Winchester brass to Lapua in 308. In my rifles, mid- level loads in the Winchester brass were pushing max in Lapua.

Thanks for you'r replies. Somewhere in the back of my head I thought I read this info. Glad I asked and thanks again.

My experience mirrors everyone's above. Matter of fact I believe the older win brass had more room in it than about any other brass, that I have used anyway. I about got in trouble once going from win brass to nosler in 243 and I even backed off on powder. There is a bunch of difference in those two in 243 at least what I had on hand anyhow....

Since Lapua brass has significantly less volume than Winchester brass, based on my .308 numbers using Varget with Winchester and Lapua brass, you'll want to drop your Varget load by almost a full grain to find that node you have using 47.0 gr. Then, you'll likely need to do a little tweaking to get it right.

I just be interested to see how he's going to seat a bullet with 47.gr of Varget in a Lapua case . Couldn't be to much bearing surface in the neck . Even with a short 150gr bullet .

My Palma load in Winchester is 47. Varget with a 155. 46.5 with Lapua.

Lapua brass is thicker than Winchester brass in the neck, Lapua and Lake City military brass can use the same neck bushing if using FL bushing dies...Not so with Winchester brass...but the LC brass & Lapua are similar capacity but LC slightly less than Lapua ...so a grain or so, less powder, would be called for with the lesser capacity cases.

I have a good deal of both brands in 308. I love the Lapua brass!

My experience has been that both Lapua and Remington are thicker brass and slightly less capacity than WInchester; however, I haven't had any case failures in Winchester or Federal for that matter as I'm pretty conservative with my brass. I've always assumed that Lapua followed by Norma were the best but don't reload and shoot one caliber enough to have enough data to prove or disprove that.
