Nice lookin for a Winchester! Is that a 24' bbl. ?

I gave up on H335 IN MY .223 not because it wasn't accurate but because of the way it acted on a hot day in a hot gun. I switched to Benchmark in both the .223 and the triple duece. I get a little more velocity and the groups tightened up also. :)

I'm not getting one holers but after close to 8000 rounds thru my wore out Remington 788 I don't expect to.:)

I started out trying Benchmark with 40gr Sierra Varminters, but I didn't seem to be getting anywhere. I tried different seating depths from the book length to just barely seated in the neck. Nothing seemed to be working. This was all in Winchester brass from 40 factory loads that I shot in that rifle, trying both neck sizing and full-length sizing. My best 5-shot group was .893, but every other one was over an inch.

Last week, I got 500 new RP cases all prepped and sorted into .5 gr increments. It turned out to be a very good batch that only varied +/- 1.6% from the average (92.0 - 94.4 grains) after uniforming. I only had one reject (off-center flashhole).

With the 40's, I couldn't get anywhere close to the lands. So, I figured I'd go with a heavier bullet and seat it .020" off the lands. I've had a lot of success with this method in my 308.

Amazing difference. I made up work-up loads from 25 to 27.8 grains of Varget with a 55 grain Hornady VMAX .020" off the lands lit by a Rem 7 1/2 Benchrest Primer.I don't know how much to attribute to the new brass sorted by weight, the different bullet, different powder, or being within spitting distance of the lands, but my groups went from being over an inch for 5 shots to just about everything being in the .5's and .6's. 2 of the 3 worst groups with this combination had one bad flyer with the other 4 shots measuring .427 and .127 center-to-center. All groups were shot at 100 yards.

I suggest that you just keep trying different stuff. I would start with trying some Varget. Also, with as small as the 223 cases are, I think attention to the details of case prep can only help.

By the way, my rifle is a a Ruger M77 Mark II Target with only a 1-12 twist barrel. You might want to get a measurement for the distance to your lands in that Winchester and use a longer bullet to get closer to them if you have to.

Here's a link to the targets.

If only that single flyer wasn't there on 5082. The flyer was actually the 2nd shot, and I actually considered stopping at that point and saving the other 3 of that load for fouling shots. I'm glad I didn't.

Even nice small groups tell a story (and those are not bad at all)...two of those three posted groups show a definate vertical component. Harder to figure out with 3-round groups, but still looks to be a bit more vertical area than horizonatal...if all three were shot at the same sight setting and you were to overlay the three into a single 9-shot, think you'd find about 1 full square (let's assume those are 1" squares) of vertical and about 1/2 a square of horizontal.

Load juggling might be a good way of getting the vertical to be less. Don't know your referecne book, but Hodgden #26 starts with 24gr. for 52gr. bulles and moves on up to a max. of 26gr. Might consider creeping up a couple of 1/10ths at a time and seeing how it goes.

go look at "accurate .223" thread

My favorite load for .233 is 28g BLC-2 behind a 55gr Hornady SPSX, and using Winchester small rifle primers. The groups started out at just over an inch at the recommended col of 2.200. I played with the seating depth untill I had all but one of five bullets touching, this with a depth of 2.285. When seated to 2.335, the group opened up to over 1.5". So you may want to play with seating depth with the load you have already worked up.
My rifle is a ruger #1, not necessarly know for great accuracy.
Good luck.

I've ALWAYS had great accuracy with 24.5 gr of Varget and a sierra 69gr Matchbthp
Also:

try the 24gr with Winchester's 55gr. powerpoint [softpoint]

I can't imagine separating brass could matter much, tho' we're told it can. More likely, the bullet and powder combo. The Hornady VMax's are extremely accurate bullets. I shoot the 40's now behind H322, and am in the 1/2" range. Trying Benchrest next.
