Does anyone have any experience with accurate 2520 loading 223 with 55 grain fmj I got 8 lb .

In the past i used it for my heavier match ammo. It performed well.

I was wondering if I need to load to the higher range since it is a slower burning powder

I dont recall my load unfortunately. Everything is packed away as the room is being used for my granddaughter

2520 is slower burning than 2230 and 2460 which are the typical powders used in 223. 2520 is often used for match loads in the 62-80 gr range. You should consult the free AA load data and work up your own load for your own gun.

I have tried it in several bullets from 52gr to 75gr.
I do have one 55gr JSP load (27.0gr A2520) group that printed .42 MOA at 200 yds from an 18" bbl... it chrono'd at 2980 fps.
Most of the other accurate groups (I consider as 5 shots under 0.5 MOA at 200 yd) were 68-75gr projectiles.

I was thinking about in the 27 grain range I just wanted to get other people's experience with it

I loaded 27 grains and it worked out good

Nice. Did you chrono it?

No I don't have a Chrono I was checking for function and pressure signs
