Re: CEB 140grn G10 MTH & 6.5 WSM-

Start with a G1 of .700 then adjust from there with the 160 Matrix, I started at .650 and I'd have to run up in the 3300fps range to even make part of the trajectory come out but there is no way that the Sherman case will push them that fast. I'm going to work on a G7 BC soon and that should really dial them in.
The BC on these have not been inflated by anyone because so few have shot it, the only data on them right now is from people who have shot it and are trying to see what it will do, I know what it takes to make the trajectory from our rifles tight at 100-600,800,1030,1350 and 1450 yards that's it, no inflating just shooting working from .650 up to where we ended up, that's why I want to see some other guys shoot them so we get more info and experience.
I'm going to go through the same process with the 140 CE and see what happens, I did a seating depth check and I can seat them and I dont' touch the throat or anything so they will seat well in the case so I should see some accuracy with them and should be over 3200fps which could be interesting!

Thanks, I will start with .700 (if they stabilize). I was pretty bummed out with the G10's not stabilizing, with any luck the 160's will put a grin on my face.

If they are indeed a .7 BC, that would be awesome. I hope they are. I'll be testing them here in a couple of months as well and will be shooting them over a 1000 yd chrono. That should help fine tune the G7.

Sounds like an interesting way ruin a perfectly good chronograph!

The 140's have a shorter nose and tail then the 130's do. I suspect the 130's might have a combined velocity/BC ballisitic advantage over the 140's. I'll be shooting both as well over the 1000 yd chrono.

A short update, I shot 8 140 CE's at the shoot in Townsend over an Oehler 35 with a Magneto speed also strapped on and they showed some very good signs though nothing was shot at paper. I had them loaded over the same load I use for other 140 bullet in my 6.5 SS, they ran an average of 3140fps which is 37fps slower than other 140s which I expected because of design and a touch more powder would bring them up. Shots over the crony at 200 meters yielded a nice tight group, I shot what did not go over the cronies at 752 yards and they were right in there with the other bullet I had loaded, did not see any weirdness. The numbers and shooting was interesting enough I'll work up a load and put them on paper till they destabilize or fall in the dirt
