If you can find any H-335, try 25 gns. w/55gn fmj. Both of my AR's love that load
Play around with the COAL a bit--
Gary
I don't have H-335 but this powder [WC844] is mostly the same thing. I'm using 25 grains which seems to be a sweet spot. I'm using 2.260" at present & plan to adjust this a little.
This was my best effort at 200 today.

And these two at 300.

Bet if you anneal the case necks, that will tighten up a bit.
X2 on what Don sez about copper mining---
What's your T.I.R. of the bullet in the loaded case? You want no more that .003.

What do you torque the action screws/bolts to?

The Bore-Tech will get the copper out but it takes a while. The old Hart barrel I shot would clean up in a couple minutes. It was super smooth. I haven't looked at this barrel with a bore scope but if it's like a couple of my other Remington's it isn't very smooth in there.
I don't understand the term T.I.R.

Haven't bore scoped this one but figure it to have plenty of tool marks & other stuff. I can get it clean but it takes a while.
RE: A Shooter - Lumpy Grits - 08-19-2014
TIR=Total indicator reading.
ROT=Rate of twist(rifling)
Bump the torque up to 45in/lbs. on the action screws.
Confirm torque on base and rings screws.
Might want to think about re-cutting the crown.
What is the paralax in that scope set to?

Thanks Gary. TIR= I'm a quarter turn on the seating die off the lands. I haven't the measuring stuff but have considered this.
ROT= 1-12
I need to work on the trigger a bit so when I go back in the stock I'll increase the torque.
Crown looks good but I'll get a good glass after it to be sure.
This scope has an AO. But I'm well aware the scope is 'bout 40 years old. I'll check the mount & rings while it's out of the stock.
RE: A Shooter - Lumpy Grits - 08-19-2014
Bullet TIR ck is for the variance/run out of the bullet in it's case, when measured with an indicator.
This is the gauge I use--

Sorry Gary. I have seen those on the bench of some BR shooters.
