Anyone want to share any 338 LM load data?

[Dogtown]

There appears to be larger than expected variance lot to lot with RL25 lately. This is making Retumbo look like a better option.

FWIW, with my .338LM SRS, this is the load that's currently working best for me:

250 Scenar
Lapua Brass
Fed 215M
94gr RL25
COAL 3.554" (still playing with seating depth)
This gives me approx 3000 fps

Sooo, I'm quoting myself a few years later. This still remains my go-to .338LM load with the COAL finalized on 3.681." I average 2985fps out of a 26" barrel with this load. While playing with the seating depth, I noticed Lapua's recommended COAL is 3.681" while their 250 Scenar factory ammo is at 3.60". The SRS allows you to seat these pretty long and I went as far as 3.75" but this particular bullet really likes to jump in my rifle, but not jump too much apparently.

Anyone shooting a 110 fcp? Berger calls for 90gr max on h100, and re25, but I keep having guys tell me they are loading 90+ I need to know if they are seeing pressure signs?

Which bullet again? Berger 300 OTM I take it? Check Hodgdons site, I believe max listed for the 300gr bullets are a bit higher than 90. I thought it was closer to 92 if Im not mistaken.

Ok- I just got my savage 111 in .338. I have dies and cases, and H1000. I'm a reloader for 7mm mag, and 300 wm.

My question- I need a load for some .338 hornady bullets.

I have a 100 ct box of 200 gr hornady JSP i want to burn up first.

Will 95g of H1000 be too hot?

I will be target shooting to 500, and possiy winter hog hunting.

Yes I plan on the Berger or SMK 300 grain loads y'all are throwing.

To be clear: it's a box of .338 200gr JSP spitzer.

Just got data showing 95 gr of H1000 under a 200gr as "light"

Max being 99- 102.

That's hot.

Lapua Brass, fed 215M, Lapua 300 scenars, 93.4 gr Retumbo

I just started load development with my 338LM and made it to 93gr of retumbo behind Hornady 285hpbt's and wound up right at about 2800fps. I'm going to load a few more up to 94gr and see if I can get 2850 before pressure signs show up. So far nothing, no ejector stamp, primers are fine, bolt cycles freely.
