No issues with my kimber 84 L ejecting cartridges. And 120 ttsx hits 3064 FPS. But maybe I got lucky with mine. It has a permanent home now b
The rifle will be used primarily for hunting out to maybe 500 yds. Thank you for the input.H4831/4350 are typical "Go Too" powders for the .284s. While they don't offer top velocities, they do offer the best of accuracy. I swapped out those for RL17 and most recently RL23 for higher velocities when needed. In my SA 284 with the 162s, I wanted 3000 fps. Didn't know if it was achievable in a SA but I found out it was. Typically you need a LA for that kind of speed but I swapped out the LA for RL17. Haven't looked back. I do go back to the H4831/4350s for banging steel and shooting ground hogs at distance.
Look at H1000 or Retumbo. Yes they are magmun powders but they shoot great in my 6.5x284View attachment 243355View attachment 243356
Doing load development the past two days with H4350 and 168 grain Matchkings in a New Ultra Light Arms .284. The 200 yd group was great but heavy bolt lift with a 51 grain charge. Dropped 1 grain and reshot today at 130 yds. Yesterday was testing seating depth and the 200 yd group was best, seated -.010 from the lands.
What velocities are you seeing with the 4350 ? At 2.975, I was getting around 2900-2925 with 4350 with the 160 Accubonds. 25" barrel. 4831 was slower.My 160 grain Accubond hunting load uses H4831sc and I’m getting a compressed load before I see pressure. Mag length on this rifle is 3”. I’ll stick with the 4350 for the MK’s and do further load testing with faster powders with the accubonds to see if I can get more speed. I don’t believe slower powders will move me in that direction with these bullets and mag restrictions. I believe Forbes was targeting 140 grain bullets.
