280 AI help with 183 Matchkings

[Stdrbs14]

Anybody using H1000 with the Sierra 183s? I need some info on where to start my ladder test. Also what overall length should I start with?

Thanks

Start at about 59.5 grains then work up. I would either load to max mag length or .020 off, you can fine tune the seating dearth later.

Not sure I would start quite as hot as Dmagna did, as I was close to pressure in mine w. 60.3gr under a 160 TMK. I would start at around 56.0gr myself, if you have no other experience with the powder and bullet in your rifle.

I have shot Berger 175s, 180s, 195s out of mine. Nosler puts their 185 RDF at max at 61.5 of H1000. I shoot 175s with N565 for my personal load.
