I'm getting around 3100fps and 1.5"- 2" groups @ my 250 meter zero. I just started working up a load with 175gr Sierra GK's with VVN570 and am getting a surprising 3170 to 3220fps. Shooting at 100yds. my groups have varied from 1.5" to 2.25" but their POI are real close together and I show no signs of pressure but that is 100+ fps faster than I expected. I think I may have something to work with though.
Dchamp, first of all, welcome to the website, and " The Brotherhood". Nice looking stick you have there, and some Beautiful country in the background.
I think maybe the reason your 160 bullets are slower then your 175's , is that the powder you are using may be too slow for the 160's, and your barrel length. I could be wrong, but dosen't your rifle have a 24 inch barrel ?
Anyway, it is working fine for the 175 grain bullet. That speed is darn good!
I love that laminated stock. Nice job, and again Welcome!!!

I check them frequently, as I have a inch pound torque wrench in my range box. Just make sure you have adequate clearance around both action screws.
I simply pulled them down and loc-tited them with blue. They'll be fine unless I somehow crush the pillars. It looks like there is some residual fouling in the barrel too that I am having a bit of a time getting out. I am working with it with barnes cr10(just picked up 2 bottles today-sale locally) and it seems to be better. I probably got the damn thing to hot working with it and baked some fouling in.

Well, Lefty7mmstw,thanks for your imput I do appreciate it.The barrel is 26" long. VVN570 might be a slow powder but I think its similar to Retumbo, not sure, and it works so darn well with 160gr and heavier bullets in the 7mm STW. I've had it up to 3300fps+ with the160gr Accubonds but that was at max pressure. I had the same accuracy that I have now but didn't like living on the edge with max pressure and I got the performance I was looking fore. I use Quickload to help me formulate loads and the 175gr gamekings are pushing approximately 100fps+ faster than predicted which isn't necessarily a bad thing but I'm experimenting with optimal barrel timing and trying to hit X node based on barrel length in the hope of better accuracy and spending less time and material in deveoping loads. If you get a chance google Long's OBT (optimal barrel time) concept. It's very interesting.

From what I've seen the 7stw and 7rum are both at their best with 160 and 175 grain pills with 50 bmg class powders like 8700 and I 5010. Retumbo will work well enough but I should think 3200 fps to be a mild overload with a 175 in a 26" barrel. I did hit 3100 fps in my 24" barrel with 171's and rl25 this summer with book loads, but they were a bit stiff and would have been 70kpsi if I had a guage on the gun. The node for that load seemed to be at 2950 fps.
I hate hunting for nodes(unless you are still accurate enough out of node) and will usually trash a load if it becomes obvious I'll have to; the rifle won't necessarily shoot in the node 100 degrees from where you are currently, so you are wasting time and barrel life continuing.

Ogle buck, that's a fine looking stick, but you better get it off your wifes bureau. She's going to beat your ass!!!! Very nice rig, and I'm sure it's a shooter. Nice job, and let us know how she shoots.

Great stuff guys. I have a Ruger that needs a new stock. Where can I look? The thumbhole stock looks good too, I may do that on my Savage, do yoj kniw if they make it for them. Lefty, stop abusing the STW or I'll have to report you to Lane S.
