I did some more testing today with my H&R 1-9" .223 and found out that it shoots 45gr Sierra SP quite well. I loaded 28gr of W748 behind them and shot 10 shots in a 1.5" circle. I then shot 5 more shots with 28.5grs and all holes were touching. I then let the barrel cool down and shot 5 more and grouped about 3.5". I am finding out some wierd characteristics with this gun. Heavy bullets won't shoot near this good.

Hello 6mm,

So, you went from all the bullet holes touching to a 3.5" group by just letting the barrel cool with the same bullet and load?

Yes, that is correct. It seems a little weird. It shot 5 shots with 28 grs (cold) you could cover with a quater. It seems to shoot better wen it gets warm. Any suggestions?

If it's got a wood stock, remove the forend, then take the forend spacer off and put a shim between the spacer and wood and reinstall the spacer. This will tighten the forend and possibly give you the "warm" accuracy. I use aluminum furnace tape, with the backing it's .004" thick, without the backing it's about .002" thick. If it doesn't work, just remove the shim and you're back to square one.

You could also put a shim on the back side of the forend stud to increase forend pressure, that's the only way with a synthetic stock.
