I have seen some loads for IMR7828, H-1000, Retumbo and RL25. I want to load som 200 grn accubonds for elk this year. I have alot of H1000 and half a pound of 7828. So i would like to stay with that powder. Anyone have a load for H-1000 in the 3200 fps range?
Rifle is a rem 700 sendero

Any of those powders with do fine. I'm sure that the Nosler Manual has loads. However, I doubt that you will get 3200 fps. If you are loading for accuracy, you'll probably get in the 2900-3000 fps range.

Asking for loads here is a "loaded" question. It all depends. A friend and I have identical 300 RUM Senderos. He cannot load a round that I build for my gun and vice versa. He can load to the lands and the round will fit the magazine. I cannot. I am 160 thousands off of the lands and right at SAMMI specs to fit the magazine.

For that bullet I load 86 grns of H4831SC at SAMMI COAL 3.60, which yields 3000 fps and 3/4" groups at 200 yds. I also load a 180 grn Accubond with 99.8 grns of Retumbo which yields 3300 fps and the same groupings. I have tried IMR 7828 with acceptable results, but I knew that the tempatures would be dramatically different on my hunt than where I developed the load. I did try H1000 and did not get the accuracy I wanted. 3/4" at 200 yds is just barely acceptable to me. I usually get a 1/2" or better, particularly with the Sendero. I really like the Accubond and settled on 3/4".

The 200 grn Accubond dumped my elk where it stood at 200 yds. The bullet hit just in front of the diaphram and lodged just under the skin after going through the right shoulder. The only issue I had was that if you are going to push a bullet past 3000 fps, you need a premium bullet like a partition or Barnes so that it stays together.

Good luck on your hunt.

I didnt realize the accuracy would diminish after 3000 fps. I will try some stuff out and hope for the best

Accuracy does not diminish with increased velosity. My comment went only to the bullet design. I have some super accurate loads that run 32-3300 fps, but the bullet is almost frangible at ranges less than 200 yds. It did kill the game at about 150 yds, but I lost a lot of meat. That load was with a Hornady Interlock and Retumbo. It printed 1/4" @200 yds. If you stay below 3000 fps, you can use almost any conventionally designed bullet, and it will perform as designed. Just my opinion.
