I took my old 7mm Rem Mag out the other day as well, just to see if I could get anything to perk with the 175 PT's. I loaded up some of them with RL22.. Nothing really seemed to come alive in this rifle.

I am using RL22, WW cases, CCI250's for the loads.

Thinking I might try some RL25 with the 175's and see what happens. As the charges went up, nothing really changed. This rifle shot 175's really well with H870, but RL22 doesn't seem to be the "one".. I have some Retumbo and 7828 as well, so those might get a chance as well.

Anyhow, what are your loads for the 175 PT's and what kind of speeds are you getting?
 
Like you Scotty - I used to use H870, for about 2900 fps & good accuracy with the 175 Nosler Partitions, or the 175 Sierra SPBT bullets. Both shot well. The Sierras were a little more accurate, but I went with the Partitions for elk. They worked really well.

After H870 pretty well left the market, had to look around some.

Tried the RL-22, and it did pretty well too for me. Play with the bullet seating perhaps?

Don't have a 7mm mag in the safe right now. Something a bit wrong about that...
 
I'm still using H870 and 175 Partitions. However, I'm on my final two pounds of H870. I can duplicate the accuracy with RL22 and 175 Mag-Tips and still get 2900 fps. I have had good success with WXR and 175 PTs, but I only have about four pounds of WXR left. I recently ran a series of test built with 175 PTs and Magnum that are showing promise.
 
Yeah, I may mess with seating depth as well Guy, but usually it seems like this rifle will shoot better than that before having to tweak seating depth...

I will take a look at the slower powders Mike. Makes sense to try them I think.
 
I did some work with RL25 and 175 TBBC some years ago. The loads were quite promising, but I didn't pursue them because I already had several excellent loads. However, the one thing that seems to hold in all these scenarios is that I was using a slow powder. My rifle doesn't appear to be overly fussy about the projectile, handling virtually all 175s with aplomb.
 
Makes sense Mike. I will get on it soon. I wanna try to make RL25 work as I am stocked up on the Alliant RL's, so if I can do that, it'll save me some problem of securing powder for my rifles.
 
I stuck to 160's. Anything that requires 175 can be done with my 180's and my 338. Too much overlap already for me.

I am shooting 160 AB's outta my 7WSM.. Wanted to try something different.

Ditto. The 7WSM is shooting 160 grain ABs @ 3000 fps. I wanted the rifles to shoot different bullets.

I figure this rifle hasn't been used in a long time. Need to see what it'll do.

Undoubtedly, the rifle will reward you for looking widely for what it might digest.

I am actually sorta surprised it didn't do better with the 175's and RL22. RL22 and a few other 160's always shot pretty well.

I am sure it'll come around shortly though. I will shoot Winchester 175 Power Points into little groups, so I know something is going to happen.
 
I shot some 175's in one of my 7mags a few months back.I was loading 63.0(2830fps) and 64.0grs(2860fps) of Reloader-22.The 63.0gr load shot much better.This particular rifle likes about one grain less than my other 7mag.You might try loading a few with a little less powder and see what she does.

I think some TLC with the COL will get you MOA.

I will give it a whirl. Thinking there has to be something to make them come together..
 
I was using 64g Rl22 with the 175 PT for 2825fps from 26" bbl, accuracy was 2 touching and 1 out about 1" at 100 yards. I was looking for a close range hunting load and figured this would do quite nicely. I was .010" off lands, tried a set .010" deeper and it got a lot worse. It shoots 175 core lokts into 1/2-3/4 moa with same 64g Rl22 and 68g of Retumbo as well, although I dont have crony numbers on the retumbo, figure its doing about 2850fps. I dont trust the core lokt bullet at all for a close range bone crushing/stopping bullet however...

66g RL22 and 72g Retumbo with 160 PT were doing 2950fps and 1.25 MOA as well, with same 2 touching or 1/2" and flyer of 1", also at .010" off...Tried them .010" deeper and again, got a lot worse. I could live with 1-1.5 MOA for a close range hunting load however, deer or elk out to 200 yards at most is all I would be asking of it and mainly 100 yards on in...

You could trust either of these two loads at distances much greater than 200 yds for deer and elk.
