60 grain Partition in 20 inch AR-15 with 1-9 twist

[Andy]

Can anyone give me their favorite loads for this bullet?

With 69 and 75 grain BTHP's I have found RL15 is most accurate in my rifle but not necessarily the highest velocity.

Advice appreciated.

223 Remington?

I've had very good luck with:
Win Brass
CCI small bench primers
max charge of imr 4895.
Shoots 5/8 groups from my 16" 1/9 bushmaster.

LC brass and about 23-24 grains of Benchmark with a standard primer does good enough in mine.

Yes, its a .223 Remington in an Accuracy Speaks modified AR-15.

I had used 4895 with the original 60 grain solid base many years ago and got 3,100 fps.

If you all have a chronographed velocity from 20 or 16 inch barrel Id appresciate it.

I have had good luck with Ramshot X-terminator and the 60gr partitions......my ar is also 20", but has a 1in8 twist if that matters...

I tried to find a load for the DPMS Panther Bull 20 Fluted I used to have. I tried several different powders including H-4895 & Benchmark and never did find a load I was happy with.

If I remember right the ones I did chronograph with H-4895 were around 3100 FPS, but I was not pleased with the accuracy.
