Is this the bullet for LR out the No.4MKII? I can get a box 500ct $200.

I’ve yet to find anything that shoots better. Loaded to around 2400 fps, it follows the trajectory of Mk 7 ammunition very close out to 600 yds. Beyond that, the higher BC gives a flatter trajectory.

Not been discontinued, but are unavailable from time to time depending on priorities and backlog at Sierra.  The answer is to buy them and stock up when they are available. I try to keep about 5,000 on hand because it may be a few years until they become available again. Much like other reloading components.

During the last shortage of SMK 174 grainers immediately post-Covid I called Sierra to inquire as to whether there would be another run soon.  The rep told me that calls like this were very helpful in determining which bullets outside of .308 caliber would be produced next and before long SMK 174 gr. bullets were back on the shelves.  I stocked up too and now that my current rate of expenditure has declined what I have on hand should last me years.  
LeHigh .311" 180 gr. solid copper target bullets appear to be back in production too of which I use to reload in my pre MkVII chambered M.L.E.  Loaded long I've had very good results with them, going from 4 moa with 150 gr. Hornady SST to 2 moa with the LeHighs.

Yeah, I learned the "buy it cheap and stack it deep" back in 2000. Just checking on these as I'm gonna stack these deep. Lol.

Now I see brass is OOS...I have 500 between Remington & Winchester. I was gonna load up on PPU, but distributor shows OOS.

Yup, same thing happens with PPU .303 brass.  Have to watch for it and then buy as many as you can when available. 

I’m finding the PPU brass does not last as long as the WWII military brass.  I’ve been tracking the number of reloads on it. I get signs of web thinning after the second partial length (P/L) resize on about 5% of the cases. That’s after 8 to 10 neck sizings between P/L resizing.  

I’m attempting to P/L size the case so that the bolt locks with very light finger pressure, but on firing the cartridge after the second P/L resize, the “white line of death” is beginning to show.  I doubt I’ll get much more than 20 reloads on these cases.  On the military brass, I would get 30 to 50 reloads.

I have a few thousand of the Indian 303 click bangs rounds. I salvage the bullets and powder.

The brass I dump in the garage wood stove to pop the primers. Hear very few pops.

    I put the cordite in the garden and burn the brass - a pop or puff now and then. Decent boolitz , great for a mad minute !.

I did put cordite in the garden when I lived in Connecticut.

If I put cordite in the red clay soil in North Carolina it turns the ground green over time.

Have used cordite to make fire crackers for holidays.

Fortunately for me brass won't be an issue for a very long time, if ever.  I've never counted all my cases but between unfired commercial, unfired surplus, previously fired but still reloadable and virgin brass I must be up around 3,000 cases.  I commenced a 5 Year Plan a la the Soviet Union before my retirement date to buy sufficient cases, powder, bullets, and primers for .303 British to carry me through my years of reduced income.  That, and I don't shoot as much as I used to so what I have on hand should last me a decade.

Oh boy, I would be happy with 10 loads each. I can get discount PPU brass in bulk, so when they become available again I'll let everyone know. 

My new Remington brand cases stretched much less than the new Winchester cases. The shoulders on the Winchesters stretched .050 first firing. The Remington was 1/2 as much at .025". I suspect my WIN cases will be toast sooner than anything else. I am curious to see what PPU does. 

I'm actually excited again about load development with the 174 SMK and potentially some PPU! Been a while since that's happened. LOL

The trick of course is to neck size only, until there is resistance in locking the bolt.     

Someone here on this site had a good idea of expanding the necks in new cases then neck size back to .308-.309 ID just far enough down the neck to form a second shoulder which holds the case back against the bolt face on the first firing. I haven't tried it yet, will have to find the right size mandrel to expand the neck.  I'm betting it will significantly extend the life of the brass.

Neck cracks can be completely eliminated by annealing on each reload. F/L sizing is a sure way to get a short case life.
