    338 Lapua Magnum

    869 is a very dirty powder. I have no experience with N570. Retumbo and H1000 are my top 2 goto powders for the 338LM.

    It sounds like you are an experienced reloader so I will discount that aspect. To get those variations in velocity I believe it must be either inconsistent powder charges or chronograph is bad. What do you use for measuring your powder charges? What do you use for your chronograph?

    What is the parent case for the 6GT or is there any?

    Powder Valley now has some Hodgdon H1000 1#s for $49/lb. I just bought 30#. Several other vendors now have H1000 but at $55/lb and higher. Wish they had Retumbo available as that is my preferred powder for my 338 Lapua Magnum but H1000 is my 2nd choice.

    Has anyone tried Peterson 338 Lapua brass? I've used their 6.5 Creedmoor brass and it's on par with Lapua and Alpha brass.

    BridgerMT: What powder did you use? Has anyone tried the new Winchester StaBALL HD powder in the 338 Lapua Magnum?

    I see no N568 on any Hodgdon burn rate chart. Please send link to that chart.

    Looks like you have 2 nodes. 85.5/86.0 & 88.0/88.5 I would probably do a ladder test from 88.0-99.5 in 0.1 increments with 3 shot groupings assuming you have the supplies. Thanks for the info.

    According to Hodgdons website you can use 85gn H4831SC with a 250 gn bullet and have a muzzle velocity 2740 and pressure of only 52000. With a 300 and 79.0 gn H4831SC powder you get 2511 at 53000 psi. Not as good as Retumbo but very doable. You seem to be only using software to make your...

    Let me know how it goes as I just picked up some H4831SC as well.

    338 Lapua Magnum

    Has anyone tried Hodgdon H4831SC in the 338 Lapua Magnum? 250-300 gn bullets?

    Just picked up some Ramshot Magnum and will be testing that powder against Retumbo.

    338 Lapua Magnum

    What was the muzzle velocity and how well does it group?

    But you can't find any Retumbo or N570 available. If Retumbo was available I would buy at least 5 8# jugs of it. Let me know how N568 works out. I have seen that available on occasion.
