7prc 175GN Accubond LR

For those of you loading the 175gn accubond lr in 7prc, how far off the lands did you end up seating them?

I load mine 30/1000s off. My PH3 is 2.65 CBTO, I load mine at 2.620. Oddly enough I was researching something else and saw on Nosler's site that they suggest 50/1000s

"Nosler recommends starting load development with the AccuBond Long Range bullets at a depth that would result in a cartridge's SAAMI established maximum overall length. These bullets have a smooth junction of their bearing surface to the ogive. This tangent ogive design provides good accuracy without the need to be at or near the lands. Often, ABLR’s actually prefer at least .050” jump before making contact with the lands."

I loaded a ladder at 0.030 off. Shooting dimes. Soon as I started seeing some velocity they got crazy and went all over. I also seen Nosler suggested at least 0.050 jump. That’s what led me to this post. I loaded with h1000 but was too slow. I think the next ladder I’ll try 0.050

What size barrel do you have? My 22" didn't see good speed with H1000 or H4831. Accurate MagPro was fast, but my SDs were all over the place. I've settled (for now) on N565. I'm at just shy of 2800fps, and 10-shot groups of 0.8" SD in the single digits.

18”, I need n560 but can’t get my hands on it right now. GRT shows I’ll get much better speeds with Retumbo, tho it’s so slow I ain’t sure how it’ll work out. I also have 4831sc but trying to put a few rounds through the stick before I use the short cut. I’m expecting that to be my best bet for the time being

I too was looking for N560, but I'm glad I found 3 lbs of N565 when I did. Even that is starting to grow scarce.

I used N560 with the 168 LRAB. 66 grains worked great.
