Talk to me goose....

[105gr]

Savage 112 Magnum target 338LM. 285ELD. Work up in .5gr increments. H1000. Nosler brass. Seated 10 or 15 over SAAMI length. I never got good results trying to stretch the bullets out.

I'm not familiar with loading for these larger calibers. but assuming it's the same for the smaller guys.

if i were to re-do that test i would:

work up in .2g increments - i feel like .5 you could be skipping/hiding a velocity node.

once you find a good velocity node, then do seating depth test to tighten the groups up.

Along with group size I like to compare where the groups are printing with respect t to the other charge weights. Is it possible to take a picture of all the groups you have arranged so the charge weights are sequential? You can leave out the dime.

your second picture (89.5) has the best ES save for the one outlier.

I'd start at that load 1st.

When you are loading 88-90 grains for a load, 0.2g increments is too small to make s hill of beans difference, as it is less than 0.25% (1/4 if 1%) of total charge. .4g and .5g is plenty small for increments.

I had the best results with Retumbo. 89-92 is where they seem to land.

Makes sense. I figured it wasn’t the exact same thought process as the smaller calibers. I didn’t consider the amount of powder. Thanks

I can't find retumbo local anywhere here

You can try RL33 too. Slower powders work better with the 338 and heavier bullets. I only use H1000 with 250s.

 

[lash]

H1000 still works plenty well with the 285s if you don’t have retumbo.

 

[105gr]

I dont have 33 either. I wanted to try those 2 powders and the shops here dont have either.

 

[105gr]

well RL26 with 300gr bergers is NOT the combo in my gun...
