Reloading 7PRC

What kind of speed difference has everyone seen with h1000vs n570 with 180s? I’ve been getting h1000 local but have been tempted to order some, 67.6 has been getting good results for accuracy but I’m floating at 2825-2850. Barrel has about 300 rnds on it
 
Anyone have results using 165 TGK? Powder, COAL, velocity, barrel length, group size?

Mine did not like the tgk. I didn’t do a lot of experimentation with it but the 180 hybrid was much more accurate. 18” barrel.

I didn’t stand on H1000 but at 67gr I was at 2620 in my 18” barrel. Accuracy was great. I’ve got a full case of N570 and was averaging 2855 last trip out. Accuracy still great. Round count is at 243.

That’s pretty smoking out of that length barrel
 
I worked up with h1000 to 68.7 And averaged 2917fps, accuracy was good and bolt throw was still easy. Very slight ejector marks tho IMG_5643.png

I’m not expecting a ton of barrel life with N570 and monitoring for excessive pressure. No stiff bolt lift with this load and the brass looks fine. Will reassess when I run out of Virgin brass and lower the charge for the once fired.
