What size groups are you getting with 69&75 grain PPU .
Also what  barrel twist are you  using?

Also what can you expect for distance accuracy, 600 Yards ?

Thanks for your help

I have shot the 75 grain PPU and found that 300 yards is about as far one can shoot before it drops like a rock. The 75 grain PPU match ammo  I have comes in a wolf brand box and I was not impressed with the accuracy. In fact, the steel cased 75 grain wolf Tula manufactured ammo was more accurate out of my rifle than the 75 gain brass cased PPU at 100 yards. That was my experience, maybe others had a better one. Barrel twist was 1/8, 18" stainless steel barrel. I got about a 3" group with the PPU and a 2" group with the steel cased Tula ammo. It could be that my rifle just liked the Tula ammo better.

Check Molons old review of the 75gr very indepth.
Youtube has guy hitting steel at 700m....just search for 75gr ppu
Been very solid for me but havent taken out past 100 yet...1.5-2"@100m for me on 75gr
1:7 twist

I like the 75 PPU as a poor mans HD round and for 3 gun. I am getting 1-2 MOA at 100 yards. Mostly it is closer to 1 MOA at 100 yards, but there are a lot more of the occasional fliers than other match ammo. Past 300 yards it isnt accurate enough to count on. I have decided to go with home loads for long distance 3 gun instead of the 75gr PPU. Those times we go past 300 the 75 PPU struggles. I don't want to be too negative. It is good ammo, just not as consistant as true match ammo.

I have never personally run it through a match grade barrel, instead using it as more of a poor man's TAP load for SD use.

That said, out of a Colt 6920, i've consistently put up groups in the 3 to 3.25 inch realm at 200 yards. Rifle is configured with a DD omega rail and an ACOG.

ETA: This is in reference to the 75g load. I never shoot the 69g.

I've shot a lot of the prvi 75gr match out of my dpms mk12.  I contistently get groups hovering on either side of 1 in at 100 yards and regularly shoot it out to 600 yards at torso sized steel.  I find it accurate and consistent.  It is the go to ammo for several of my friends as well for long range shooting.

I consistently shoot 3.5-4.0" groups with 75gr PRV in 1 in 7" twist barrels.

I have even shot a 3.75" 5 shot group out of a 1 in 9" twist Bushmaster ACR a few years back.

I consistently can but 5 shots of the 75gr just under an inch at 100yrds with my 20" ARP barrel with PA FFP scope. Ranks up there with AE Grey Tip as one of the best value accuracy loads. It does better over longer range though than the AE.

This.  I have the same upper and I usually get about 1.25 moa with this ammo.  I haven't shot groups further than 540 yards, though.

I've shot steel out to 1k with decent results.

Both of my Knight's SR15 Mod1 16" 1:7 like the 69gr more than the 75gr.
I consistently(90% of the time) get 1 to 1.5MOA 5-shot group using the 69gr.
When using the 75gr, 60% of the time 1.5-2MOA, 30% of the time ~3MOA.

Overall, PPU 69gr is good ammo for my SR, your rifle might like something else
