338 edge 270eldx r33 seating depth test 300yds

[Mram10us]

Running Bertram brass. Always used 375rum brass before that with great results. I shot the 300smk then the 300 Berger but wanted to try the 285 and 270. 285 was great but I ran out.

Not a 338 Edge, but similar. My H1000 338 RUM load with 270 ELD-X came together at 87.3 grains with a CCI250. Nosler brass, bullet seated .015" off the lands. OAL 3.800"

Thanks Brent. I'll shoot in the morning and post results with h1000 ladder

My 338 Rum load !

I don't have an edge, thought building one but my 338 rum is doing fine. 285 eld-m with 86.0 of rl 26 produced 2886 fps

got a question for anyone interested. whats the difference between the 7mm Viking and 7mm stw

Weren't you running 270s with RL26 at great speeds and tight groups earlier in the year? If I recall, they were 0.100 off the lands?i follow these threads closely for info as my 338 rum will be done soon, it'll have a 28" barrel.

Yes. That's my RL26 load with a 270 ELD-X seated .110" off. It's common for me to have a primary and secondary load. The difference in velocity is 50 fps, which is normal between RL26 and H1000.

I wish I could find an 8# jug of H1000 or two!

I would do .003 increments for seating depth changes. Its very easy to skip over a sweet spot.

I'll do that once I narrow it down. Thanks

Thread caught my eye... I've got a 338rum that holds .25 moa with the 270 ELD-X, .010 off the lands with 95gr RL-33.

Seating depth is critical in my rifle to be up close with any bullet, maybe RPierce is right that you just haven't found the correct seating depth yet?

I wouldn't give up on the 270 ELD-X, they can really shoot!

 

[Mram10us]

Not giving up on the 270s ... but they are on a short leash
I might revisit the seating depth around 3.900 in small increments. It's just not normal for the rifle to be finicky. The 300smk, 300berger and 285 testing was easy.

View attachment 156533 Not having any luck with the 270s and r33. Think I'll try another powder cause this combo isn't showing much promise. Base load of 100.5 r33 f215 primers and 3 shots of each coal. It's only 3 shots, but I've tried enough of these to know the rifle doesn't care for this combo. Ideas welcome

H1000 and try 285 eldm...had no luck with 270 either...
