Picked up a few bags of 140 E-Tips a couple weeks ago and am wanting to try them in my 7-08 but am a little unsure of which powder to try first. Keeping my COAL at 2.80" will put me jumping them about .085" so I'm within Nosler's .050-.10" off the lands. The rifle is a 20" stainless 700 so I know I'll be a little slow on the speed side but just looking for some suggestions on which powder might work best with this bullet. Anyone used them in their 7-08 yet?

Big Game for all 140's and under in 7-08...
Near max load should get you at 2,900 or close to it...

I'm using a 140 TSX with 47.2 grains of RL-17 seated 0.060 off the lands. Getting outstanding accuracy in my gun.

H4350 or R-17 was kind of what I had in mind to try first. I kind of assumed I needed a little slower powder since the E-Tip has such a long bearing surface.

I've had four different 7mm-08s and they all liked RL-15. To be honest, other powders may work at least as well, but I have never seen a need to try anything else. In my rifles, (and work up to this) 41.5 to 42.0 gr. with 140 gr. bullets give me a little over 2800 fps. and accuracy is superb.
If we live long enough, we all have regrets. But the ones that nag at us the most are the ones in which we know we had a choice.

Just a little update on this, I worked up a load with some 2000-MR today and hope to try them out across the chrono tomorrow. 45.8 gr and the E-Tip turned the little 7-08 into a 280 wannabe.

2800 (2997 and 2806) fps at 45.8 gr and 2815 (2810 and 2820) at 46.0 gr. Not too bad for a 20" barrel I thought. Gonna load up 5 or so of each tonight and see how they group next time out, hopefully tomorrow.

Let us know how they do; accuracy is where it's at, velocity is secondary (within limits).

My Ruger 7-08 likes the 140 gr E tips near Max with RS Big Game.

I have found that .100" jump is where the best accuracy is with the E Tips in .257 100 gr, 7mm 150 gr and 338 200 gr.
Keep in mind that the E Tip has a long surface bearing and pressures spike quickly. Nosler recommends the mid range loads as MAX so work up carefully.
