[QUOTE="Broz, post: 449818, member: 7503"] It was a Hybrid...:D I used what I knew from a 300 win with a 180 weight bullet. started low and worked up with H-1000. When I got close to the charge I use for a 300 win with a 210 bullet I had accuracy and great velocity. That was good enough for me and I stopped there. This is probably a repost but I find this important. When I changed this load from RP or Win brass over to RWS brass it was HOT. I had to back off 3 gr of powder to make it happy again. This is due to the strength of the RWS brass and the fact it has less case volume. Then we tested our drops at 700 and 1000 with the new lower charge and brass. The drops were the same as the 3 gr heavier charge and RP / win brass. So I recommend RWS or Lapua brass and starting low with H-1000 and a 180 Berger. Probably 68 ~ 70 gr or so. Jeff [/QUOTE]
