    I just bought a Sendero II in 300 rum. I will be using it to hunt whitetails and hogs out to 600 yds. Do any of you guys have any pet loads or recommendations of where to start. Also I have both FL dies and neck sizing dies. Could someone explain which is more beneficial to me, I'm a beginner at this.

    I am also fairly new to the 300 RUM, and have been doing some load development, I am using 210gr Berger VLD, with H1000 standard seating depth of 3.60 (from Berger) Rem brass, and CCI 250 primers

    [​IMG]

    here is 87 g H1000, 5 shots at 100yds (pulled 1 out), avg vel- 2852fps

    and here is 88gr of H1000, 5 shots, 100yds (pulled 1 out here as well) avg vel- 2913 fps

    Maybe not the best in the world but a petty good place to start I figure, probably will play with the seating depth a little, and try 0.5gr incraments as well. Hope this helps.

    I prefer full length resizing. I currently shoot a 200 AB with Re25, Federal cases, and either WLRM primers or Fed215 Match primers. I have the Berger VLDs in 210 to play with. Other powders that work well are H1000, Retumbo, US869, and WC872.

    100 grains of Retumbo pushing 180 grain Barnes TSX. Sub MOA groups out to 400 yards, and sub inch groups at 200 yards. The load is lightly compressed, which Retumbo seems to like, I've got 3 other rifles that really like Retumbo when it's a compressed load.

    You are tougher than I am, this thing kicks way to hard to be shooting at anything smaller than an elk with. I'm AFRAID to shoot it prone where you can't give with the recoil. I'm afraid it will break something like my collar bone.

    im new to this also. i shoot 89.5 of 7828 behind a 180gr scirocco. i would like to try 180gr ab. do you think 7828 would work. sciroccos are expensive to buy. the accubonds are a better price i think.

    I have a pet load using 165 gr. Nosler BT's and H1000. Shoots really well and this load would fit the bill for what you said your intentions were. I will double check the charge later and report.
