7mm Rem velocity throated for 180 ELD-M

[Deleted member 25294]

Just wondering what sort of velocity people are getting with a 7 rem mag and 180 ELD-M's that is throated out to about 3.6" or so..
I've used H1000 and Retumbo in a 7mm with a saami throat that wasn't very impressive, i.e 2875 with 180's.
I would really appreciate some data from you guys; powder, OAL, etc.
Thanks

Factory Remington 700 long range, 26" 9.25 twist w/SAAMI chamber, Hornady brass, CCI 250 primer, Reloder 26, and 180 Berger VLD seated .005" off the lands - 3015 fps, e.s. in the teens. With H1000, I hit 2975 before I saw pressure, best accuracy was around 2900-2930 fps, e.s. in the 20's. With Reloder 26, I hit 3070 fps before I saw pressure, best accuracy was 3000-3030 fps.

I think most are answering with Berger bullets not the eldms which has a longer bearing surface( apples to oranges).

I'm shooting 2841 with a under max load in a standard savage 116. I have shoot a full grain over what I'm using now without any pressure signs. I shot yesterday in 90 degrees weather. Shot a .5 moa at 300 yards, but I feel I can tune the load better.

24 inch barrel
Good luck.

This absolutely can have an effect, but I have not always seen it. For example, I developed loads in my .260 AI with 140 VLD's, and also with 143 ELD-X's, and I hit max pressure within 20 fps of one another, even though there is a difference in bearing surface and wieght. And at the end of the day, the 143 actually shot more accurate at a faster node than the 140 VLD did, the 140 shot best at 2930 and the 143 shot best at 2955, max for both was right around 3000-3010.

Not saying your point isn't valid, it absolutely is, but sometimes things don't always happen like we think they will, I was surprised at what I saw in my 140 vs 143 test.
