22 PPC load for 69 TMK

[slancey]

I have a 22 PPC with a 1:9" twist rate and I'm looking for a good load using the Sierra 69 grain Tipped MatchKing. I have plenty of H322, Varget, and H335. Has anyone tried heavy bullets in 22 PPC? I can probably start with .223 Rem. loads and work up, but I'm open to suggestion.

well thats unfortunate Im also looking

I would start with the max charge of H322 or Vargrt for the 55gr bullet and work up from there. I would lean toward Varget, H4895, VV135, or something in that range of powder burn rate.

Ive shot 70 gr in mine. N-135 did well. H322 was a bit fast burning.

@Ramblerman , 28gns of Varget and a 90gn SMK goes 2930fps in mine (30” 7.5twist with 0.100 fb). It shoots fine all the way down at 25gns of Varget too (no hang fires or soot on the shoulder), so you should have a wide window with Varget to start low and work up. Benchmark and IMR-3031 both worked very nicely and are the fastest powders I’ve tried, although with nothing lighter than a Berger 80gn VLD.

Thanks Evan! You're always full of experienced data. I have some test ammo loaded up with SW Precision (i bought it when Varget was unobtanium) in that range that Ill give a try...im starting a bit lower in defference to the little Sako action and untested barrel and chamber...I'll hotrod the Bordens...but not this Lil guy. Kind of a S&W K frame vs N frame 357 mag situation. Hahaha
