Welcome to the forum.
The E-Tip has a long bearing surface which increases pressures.
Use the existing Nosler starting load data but the MID range loads will be your MAX.
It is always recommended to start low and work up any load but it is imperative that you follow this procedure when loading the E-Tip.
Start at .100" off the lands.

Welcome to the forum and JD338 gave you outstanding but very important advice and directions concerning you loading the E-Tip. Follow his instructions as if it came straight from the bible, it did, the Nosler bible on reloading the E-Tip. I hope your load work goes well and if it does the E-Tip will prove to be one tough constructed bullet on anything it hits.

Glad to hear that you are a long time user of Nosler bullets.
I have tested the 7mm 150 gr in my 280 AI and the 338 200 gr in my 338 RUM. Accuracy is excellent and penetration is impressive.
I do not think you will be disappointed.

What were you using as your primer in your loads?

For both the 280 AI and the 338 RUM, I use Federal GM215M primers.

Thanks...
I am using CCI Large Rifle for the 308. If anyone else has a recommendation I am interested.
Thanks to all.

I just picked up some 180gr E-Tips to try in my .300 Wby. Will be loading some up and will post my results.

Start out .100" off the lands, the E-Tips like a long jump.

Sorry for the dumb question, but how do you measure distance from the lands? Specifically .100"?
I haven't really played much with seating depths and usually just seat to recommended OAL as per reloading manuals

That is a good question and I am glad you asked.
The fastest easiest way to do this is to take a fired case and make the case mouth slightly out of round so that it will hold a bullet snugly. Seat the bullet out so that it will engage into the rifling.
Carefully chamber the round and remove it from the rifle. What you have just done is put the case into the chamber, the bullet has touched the lands and is pushed back further into the case.
Measure the COL of this "dummy round". Write down this measurement and subtract .100". Now go through your loading process and seat your bullet to the new COL. IF you need to change the distance, reference the COL dimension to the lands and adjust your seater die accordingly.
You can also invest in a Stony Point to do the same thing. Just remember that if you change bullets, you will have to redo the process to get the COL to the lands for that bullet.
Hope this helps.

I believe Hornady now manufactures and markets what was previously known as the Stony Point OAL gauge. It does work quite well.

The nice thing about the Stoney Point (Hornady) guage is that once you measure, you don't have to re-measure when you change bullets, since you're measuring from the ogive.
Boomer, I'll add a little to what JD's saying, in deference to your chosen arms. I've loaded the E-Tips in 270Wby and 300Wby, and you won't be able to get them touching the lands, I bet. What I did was start at mag length (which was awful as far as accuracy is concerned, in both rifles!) and shorten up a bit to find the sweet spot. That's what I've always done with the 'bees. Now, with the E-Tip, I've come to the same conclusion as JD - they like a lot of jump. I've had success anywhere from .030-.100" shorter than the COL's I've used for traditional lead-core bullets. So, knowing what I know about these bullets in Weatherby cartridges, I'd start about .025" below mag length and work back in .005-.010" increments. Good luck with the shooting.

Thanks very much for the advice guys, much appreciated. I will pick up one of those OAL gauges for sure. I will have to start playing with seating depths now

Pat,
Welcome to the forum. We're glad you're here. Undoubtedly you will find a wealth of knowledge from people who collectively represent centuries of experience. Probably the best way to start is with a good manual, and adhere to the formulas presented there in. The 6th Edition Nosler Guide is an excellent reference for beginning loading. Remember that with E-Tips, to limit your maximum charge to the mid-range listed for the BT, AB and PT. As you become more familiar with the techniques of hand loading, you will undoubtedly experiment with varying powder/charge combinations.
