223Rem loads PP2000MR 75gr

[ASbobcat]

Looking for BOLT GUN load data in 223Rem/5.56x45 with PP2000MR behind 69-80gr bullets. Specifically looking for 75gr ELD-M, but can extrapolate =/-.

Please include bbl length with MV.

Thanks

Not going to put my load down, but this is for gas gun and 18" barrel with 77 Sierra TMK, LC brass and wolf SRM. A good place to start would be 23.5 grains of MR2000 and work up. I'm pushing mine at 2739 fps and have gone higher, but that is what velocity it shot good at. Obviously you can push a bit further in bolt gun.

Too many variables to extrapolate gas gun data.

Please limit responses to BOLT gun ONLY!

It has been a few years, but I had success with 2000-MR in a 223 Tikka and a 223AI, using the 75 Amax.

223 Tikka Sporter
75 Amax
24.8 grains
2.390 COAL
I did not chrono the load but was able to make impacts on a 900 yard steel target

I cannot locate my notes on the 223AI load but I had a two groups in the .2s when testing.

Hope this is helpful, though not precisely to your specs.
28" Shilen
Berger 85.5 Hybrids
1.933" CBTO (of course this is specific to my comparator)
26.0 grains PP2000MR
2,800 FPS +/-10 (LabRadar)(75°F)

Sorry, no data on lighter bullets.

Too bad you can't recall MV. Ballpark figure?

Thanks, that's very helpful. My bbl is also 28in. I can extrapolate the rest.

Appreciate the info.

I'm pretty sure I was using 2800 in the ballistic calculator

Years ago I had a slow 2KMR. One of the load work at 600 when the 80.5 first came out with my service rifle. Aiming target is SR3 with 3 inch X ring.
