It will be great to see that rifle collect some game shortly; and it does appear to be ready for the hunt.

I haven't tried Retumbo with 160's but I think it could push the them a little faster than H1000 can. I know I get just under 3100 even with 175's and Retumbo. I just didn't have enough of it to really work with, so I stuck with H1000.
I'll be watching your RL22 and 150 loads.. They sound real good.

I can't wait Mike. Its functioning well and the accuracy seems pretty good as well. Really thinking it'll be a nice rifle in the open country.

Did a little shooting today with some 160's to see if the ogive measurement of the 175 PT would hold up for the other bullets. Unfortunately, the only one that printed close was the 154 Hornady.
The 160 Swift A-Frames weren't too bad. I imagine with some work I could make them come together.
160 Woodleighs were off in left field, literally...
160 PT's were in the same area for the group, but just a large triangle.
Two 175 PT's for reference were just a touch low at 100, but I figured it would be good enough for what I was trying to do..
Oh, almost forgot, the 175 Sierra Gamekings weren't horrible either. Some of the poor shooting could have been the HEAT! 90+ degrees and bright.. I thought I started early enough, turns out I am going to treat range work like turkey hunting and be in an hour before light! :lol:
Might try some of the 175 Hornady's and see how they match up.. The the 154's shoot like that, the 175's might not be half bad either..

pretty darned nice , this 7 - MSM sure seems to work well with little effort .
Scotty , I've noticed before that a lot of stuff happens at the 90* temp and higher . I seem to do ok in the high 80's , but get to 90* and things change . I usually get high humidity with the higher temps , this kind of weather stinks . three shots make enough heat to fry an egg , and it takes forever for the barrels to cool .

Your right Jim. This thing is easy. Never would have guessed a rechambered factory sporter would be so easy to work with.
Yup, this sorta heat makes the wheels fall off pretty quick. Heck, the rifle is probably fine but I can't handle the darned heat.
Really thinking on getting a reamer and ordering another barrel I like it so much. The barrel won't rot and it'll be nice to have it around when this factory tube finally dies out.

You've got me thinking of rebarreling the 300 Weatherby to 7mmMSM with the way yours is working.

Man that thing needs an elk in front of it. Pretty light and handles well I imagine.

I've thought this too , Scotty would know better than me .if you like the mark V , I think this could be as easy as screwing on a 7mm bbl . you would have the correct bolt face , and lots of magazine length . this is probably a cheap way of trying out a 7MSM .

Jim it's a Vanguard but it still has the right bolt face and plenty of room in the magazine.jimbires":3b2o6e9b said:

Anything with a .532" bolt face would work fine for the conversion or rechambering. I'd want at least 3.6" in the mag box for space. Other than that you'd be just fine.
If it's something you just wanna try out, I'd say just rechamber any old 7mm Rem Mag. Easy stuff, it'll clean the chamber up nicely and you'd have a straight and decent chamber to work with. Pretty cheap if you can borrow a reamer from someone.
