I agree with this. I was thinking the same thing. But I would also clean with BoreTech. Maybe that is because I use to shoot TSX's in 30-378 accumark and it fouled so bad it took 3 sessions of clean and shoot to get it back to a solid 3/4 moa rifle. The rifle was sending them very fast and that is badd juju for coppers in my opinion.

Ok, just to update this thread.....I shot a ladder with RETUMBO and 230's a weekend ago with similar dismal results to the H1000. See below but lots of horizontal stringing, this time to the right but nothing really jumped out. I still think it's kind of wierd and was thinking my barrel may be giving it up as I am getting close to 1000rds through it now or my scope had developed some internal problems so I went back out yesterday and fired three shot groups at 100yds to verify everything was fine ( The Rifle is sighted in with the 180TTSX @ 200yds) and it still shoots the TTSX's very well. I think I am going to focus on the new 200 LRX bullet even though it's BC is not as high and will have to try again with the 230's. I having a 300 Win re-barreled now and throated for them so I'll save my remaining stock to run down that tube as my Wby does not seem to like them.

You might try adjusting your seating depth and see what happens? I don't think your barrel is toast when it groups the Barnes that way.....Rich

shots 5,6,7,8,and 9 form a rough circle.
shots 11 thru 15 form a larger circle.
I think your just seeing barrel whip here?

shots 13 and 14 look promissing. I would retry those combinations again.

I assume that was also shot at 200 yrds.

For an alternative theory, what's the twist rate in your barrel? Hopefully it is 1:10. If it is not, you may have a bullet stability issue.

Exactly what I was thinking... .

For whatever set of reasons this particular rifle just may not like anything over 200gr's.

If it were me I think I'd try to load up maybe ten each of a couple of other high BC bullets in the 200-210gr range and see how those compare.

There's enough of us on here shooting various weight 30's in high BC bullets I'm sure he could get a handful of bullets for the asking to experiment with.

Good thought on the barrel twist.... It got me thinking so I just measured it with the old tight patch on the cleaning rod method and I get an average of 10.5". I just assumed as its a stock rifle it was a 10" twist....might be on to something here.

As for the shots 13&14, those were the best I saw too and the three shot group was with them @ 102.8 gr. on the right, it's not bad at just over 1 MOA and I would have been happy 20 years ago but I'm wanting better nowadays.

I have had fairly good success with the 210 VLD's in the past and was just wanting to e experiment with the 230's as they really buck the wind much better than either of the TTSX loads I currently have.

I'm happy with the 180 TTSX load for my urrent hunting needs but also enjoy having more than one good load worked up for a particular rifle!

Thanks for all the suggestions!!
