338 Norma Loads
10/20/2014 Last edited 10/21/2014 by midgetorama
[HR][/HR]I am shooting a 9.5 twist Bartlein that finishes at 26".

With a 300 grain SMK I am getting slight ejector marks with 85.0 grains of IMR 7828 SSC and a CCI250 with Norma brass. Velocity is only 2715 fps.

The best accuracy with this bullet, powder, primer combo is 82.5 grains at 2632 fps. Single digit ES.

I am seating the bullet with a 0.025" jump.

I was expecting better velocity. I may try Retumbo eventually.

I have a good buddy that is using us869 in his 300rum pushing 230s. Ive thought about it, but what he is running into is a lot of carbon buildup, carbon ring.

If a guy is looking for a powder, definitely give rl33 a shot. Ive ran some of it and it gives excellent velocities.

[HR][/HR]Here is some info on rl33.
97.7grns rl33
300grn berger otm.
215mag
2863fps 26" barrel
3.725" coal - single load.
Es 14.22
Sd 7.00
This gave me a 0.103" center to center group at 100yds.

I did a quick velocity check prior to loading for groups.
1. 95.0grn-2738fps
2. 96.0grn-2788
3. 97.0grn-2732 - velocity dip.
4. 98.0grn-2861
5. 99.0grn-2899 - hard bolt lift

I shot these 5 rounds at 300yds and the resulting group was 2".

It'll fit...

I know it seems like a lot, but the density of the RL33 is higher then say H1000 where you'd have a hell of a time with 90grns.

Looks like I'm going to have to give the reloader 33 a shot in my .338 Warthog... (.338 NMAI). I'm currently running 93gr of Retumbo with Berger 300gr OTM's @ 2893fps out of a 28" Bartlein 1:9.3

I've got some data for you on the US869.
90.0 - 101.3grns US869
300grn bullet
@100.0grns = 2710fps

Now this is not my data so start low and work up. Same as usual.

89.0 gr of H-1000 with 300gr Berger OTM

3.602 Cartridge Length ... I'm a couple thousandths off the lands.

Averaging close to 2800 fps from 27" bbl.

5-shot groups were 1.125 @ 200 yards.

I managed one 3-shot group at 200y for 0.625" NOT sure I could reproduce it.



I'd strongly recommend Berger boolits across the board. My 6.5 CM loves them too. Super high ballistic coefficient on both calibers.



My Retumbo tests for 338NM were averaging 2715 fps.

Close to 2900 fps from a 338 Norma out of a 26" barrel?

How is brass life?

I`m building a 338 Norma with a 30" Pacnor 1-9 twist barrel and hoping for 2850 fps with good brass life.

brass life seems to be good. I'm not running a lot of the rl33. my main load is h1000 which i have previously listed on this page. but with RL33 a guy can get up there in velocity. Just giving the guys some insight. My numbers will vary from others.

Settled on 89gr of H1000 pushing a 300gr Berger. Shot it on a ridiculously hot day...occasional ejector swipe, primers look good, no sticky bolt. At 1071 yards it hits steel with authority.

15k off the lands
AVG 2809FPS, SD of 4.3, ES of 9

Also will note that for my barrel the POI is the same for both 88gr and 89gr of H1000.

I'm getting ready to start load development on my new 338 norma mag. I will be running the berger 300's and RL33. I was just wondering what everyone else's load looked like running this combo.

Like your results, Having a rifle built now similar to yours , same trigger ,Barrel will be a Brux 9.3T 30" , will be using H1000 to star around 87.0 and up from there , were you seeing any pressure signs at 89?
