Correct, resized(small based/rcbs) and trimmed.
Yeah, that's a very good way for comparing and showing the differences.
www.snipershide.com Guess who made Black hill match brass ……..Winchester!
can't comment on the Rem BR brass, and not sure how much different this brass is, but it does have a larger flash hole than most SRP brass.
The twist all depends on the length [not weight] of the bullet you intend to shoot. Search the new bench rest records , the 30 Cal. shooters are using custom bullets in the 110-115 gn. range and using a 1-13 to 1-14 twist.
Yes, I was looking at the crimp too! And yes, 41 grains with a light crimp looks good.
The brass definitely looks like you're way over pressure. The first thing that come to my mind is, did you measure case volumes for that brass? I ask because I've heard that the Alpha brass tends to have walls that are somewhat thick, which reduces the case volume. And with the amount of powder charge you're using, that could really boost the pressure up. In addition, the crimping could add to it depending on how much crimp you're using. With a fast burning powder like Accu 2200 at 45 grs, it just looks to me like too much powder charge.
Thanks 4 the tip on the print.
Your correct, I thought about that too, Looked, and Nosler doesn’t make a 115 grain BT, but they DO make a 150 grain BT, and when I pulled the bullets on a few, weighed them, BINGO!!, 150 grain!!!

Most Light 30 cal bullets in benchrest are being used in 30 BRs , not 308 Winchester . They will work in .308 Winchester , I use them at reduced speeds and they work quite well for what I am doing .
That distance to the lands doesn't tell us much since various chambers have various freebore sizes in addition to variances in comparators. Though COAL's have variance, at least when that's stated (with the bullet weight too) it can give us all a better idea of what you're cartridges are seated like compared to our own chambers.
And I'd have to be filling the case up into the neck to start crunching any powder. These measurements are using a Hornady comparator insert where using my Sinclair comparator insert the measurement is .052" less because of the difference in the comparator's diameter.
Thanks for all the good info. My rifle is a savage 110 tactical. 2.760 to the lands. I’m going to start over but the eld-x in 200gr is very long.That distance to the lands doesn't tell us much since various chambers have various freebore sizes in addition to variances in comparators.

In my current Krieger .308 barrel, my distance to the lands is 2.274" for 169 SMK's (OAL=1.301") and I've loaded the cartridges to a CBTO of 2.261, which is .013 off the lands (COAL=2.957). That COAL barely fits in my non factory magazines.
You should easily be able to load .020 off the lands with plenty of room for 41gr of IMR-4064. So, what you're saying is perplexing and suggesting maybe something going on with the seating measurement???
What's your COAL when it's touching the lands at 2.076?
I have decided not to go any further. I’m sure that I made a mistake at some point. I have pulled the bullets. I thank you for your time sir.
I just loaded 200gr eld x’ s into a savage 110. See the previous page. My cartridge that is 2.24” base to ogive is 2.897” in total cartridge length. I am trying to figure out, as are others, what your 2.76 represents. I would love to help you, but just need to know what the 2.76 is. And yes, these bullets are very long. It is pushed down way past the neck/shoulder junction. For me, and my rifle, it does not hurt a thing.
What comparator insert are you using? Looks like it might be like my Sinclair one.
Using a Hornady comparator set. Here is a couple pics of what the depth is. Let me know if you have any other questions. The lands are at 2.255 with this bullet. And the powder is 748. Almost forgot, it’s a Federal Gold Medal Match piece of brass.
Thanks. I think R.STOCKFISCH might find that info helpful. And here's some more info for him and you that might be found helpful:Using a Hornady comparator set.

I’ve got a Savage 110 Elite Precision that shoots everything I throw at it pretty good. Decided to try some 200gr ELD-X’s, because why not. Loaded from 40 to 41.6 in .4’s. Never made it to 41.6 as 41.2 showed some ejector marks and 40.8 had already shot well. So I decided not to push it. No velocity readings and only 3 shot groups. Loading up 20 rounds at 40.8 right now for confirmation and velocity this weekend. Shot thru a YHM Resonator K and recoil was stout. Rest of the info is on the cards.
