.243 RL-17

[ewc]

Ran the 80 TTSX thru today:

Win brass, WLR primer, COAL = 2.725", 55 deg F, no wind

My barrel seems to be slow by 50fps. Please note my COAL and know that you need to work up-

Avg (3shots each):

41.5=3000
42.0=3050
42.5=3100
43.0=3135
43.5=3160
44.0=3258
44.5=3325
45.0=3378
45.5=3432
46.0=3500

Most groups from 41.5-46.0 hovered at 1 MOA. 46.0 was exceptional = 0.220".

RL-17 never showed pressure. Even at 46.0gr.
I'm probably going to get it back down to 3,400fps.

Use at your own risk.

What gun and what length barrel? Impressive results no matter what.

Those are awesome results. I have a ton of 243 brass and I haven't even started to reload them yet. RL17 is one of my favorite powders. I have been getting 50 to 100 fps faster with no pressure signs.

That last group with 46.0 gr. is awesome.

has to be a match chamber and very long barrel to reach those velocities

Nope. Stock A-Bolt- 22"

And 50 fps slow.

46.0 is 1/2 over max. Barnes says I should have hit 3,470 fps with 45.5. A review of others testing this same combo (24hrcampfire, snipershide) says I am slow also.

Like I said, I never hit pressure- primers, case head, and bolt lift were cool. Speed is telling me to back down- nothing else.
