My 300 win will shoot 200 gr Accubonds into a very small hole with whatever powder I use, IF, I keep the speed around 2850. That being said I can shoot the 210 Berger VLDs faster and with less wind drift. I like H-1000 the best. Good Luck
Remington 700 5R 300 win mag 26" barrel IMR4831 67 grains same hole accuracy...
Now with that said Nosler bok says 2862 fps chrono'd get 2741fps. Other loads chrono'd fine.
Yes I rechecked the load pulled bullets and checked the powder charge.
I have found in my custom 300 wm 26" shilan barrel 1-10 twist rem 700 action 200 grain accubond. The best load i have is fed brass fed 215 match mag primers78 grains H1000 200 accubond seated .30 off for an average velocity of 3060 fps .75" group at 100 yards. Realy looking forward to getting my hands on some of the new 210 grain accubond long range should preform really well.
