I have been using H4831 with 250 grain scenars, but would like to load some 300 SMK and I was wandering if anyone has used this powder with 300 grain bullets.The Sierra manual shows it, but have noticed a lot of shooters are using RL25 . Any input would be appreciated.Thanks in advance.

4831 is just too fast. Buy RL25 start at 87-89 grains for the 300Gr.SMK or Scenar.

Thanks Lt. Arclight, I saw a lot of shooters used RL25 but did not see it in the sierra manual. I had some H4831 and thought I would see if anyone was using it.

If 25 doesnt work for you try Retumbo....have had exellent results with it and 300gr SMK's and 300gr scenar's.

+1 for the Retumbo, having great results w/ 300smk's & 215m primers. What rifle and barrel length?

Re: H4831 for 338 lapua
I would go with Retumbo first the H1000 second. H4831 can be used with light loads and 250gr projectiles but it is a waste of the cartridge get retumbo as it is also more stable than Re25

Re: H4831 for 338 lapua
I would start with 250 gr with that 1:11 twist. and if u r goin for precision and quality go with VihtVouri powder.... HANDS DOWN. as far as bulletts i like the 250 SMKs ofcourse and the 250 lapua lock base scenars. The Finns have been mastering the 338LM for far more yrs than the US. They use a 1:12 twist @~27" barrell with a MV of about 2950. If u want more details PM me, ill give you my load data which comes direct from some heavy hitters, and it works awesome for me

Re: H4831 for 338 lapua
In my Sako TRG 42 I use 99 gr. of Retumbo with 250 Lapua bullets loaded to 3.68 oal which chronos at 3000 fps. I tried H4831 SC, but had poor accuracy and low velocity. My rifle has 1/10" twist. The 300 smk try 92.6 gr of Retumbo which should be around 2800
