INFORMATION

I've found very good accuracy as well as top velocity with H1000 in 2 different 270 WSM's!

I saw this; it might help. Cheers 🫡

For Reloder 19 (RE19)

  1. IMR 4350: Slightly faster than RE19 but widely used in .270 Wby. It provides good velocity and accuracy for 130-150 grain bullets.
  2. H4831 (or H4831SC): Similar burn rate to RE19, though slightly slower. It's a proven powder for magnum cartridges and works well in .270 Wby.
  3. Norma URP: Close in burn rate to RE19, offering consistent performance in magnum loads.
  4. Vihtavuori N160: A bit slower but suitable for .270 Wby with heavier bullets (140-150 grains).

For Reloder 22 (RE22)

  1. IMR 7828 (or 7828SSC): Very close in burn rate to RE22, excellent for magnum cartridges, and widely used in .270 Wby for high velocities.
  2. H1000: Slightly slower than RE22 but effective for heavier bullets in .270 Wby, especially 140-150 grains.
  3. Vihtavuori N165: Comparable burn rate to RE22, good for magnum loads with consistent performance.
  4. Norma MRP: Matches RE22's burn rate closely and performs well in large magnum cases.
Thanks 436! Very well done sir!

Great post, 436!
