Re: 168 Barnes lrx in a 9.5 twist?

My 284 is a 1:9 twist Schneider 28" and did not stabilize the 168 LRX. They tumbled at basically sea level 90 degree weather. So I tried the cutting edge bullet which is also a solid. I used the 160 gr HPBT Max bullet. I have a long Defiance Action so OAL was not an issue with this bullet. Shot extremely accurate with 59 gr of Win780 and WLR primer. Slight pressure but just over 3000 fps. Pressure sign was slightly flat primer but brass ejected fine. Probably should back to 58.5 gr but shooting super. Seated bullets 25 thou off lands. Shoulders backed only one thou. Work up from 57 gr or so if you try the Win 780. I ladder tested 5 powders and it was the best WITH this bullet. I use Lapua brass. If you use Winchester which is also very good brass start lower bc it produces higher pressures than the Lapua does in my experience. Not a bad thing just requires less powder. Just be careful bc there is a difference.

With the Berger 180 VLD in my gun likes 52.5 gr R17 and CCI BR2 primers 35 thou off lands at 2830 fps - very accurate and more so 300 yrs and beyond. At 400 to 700 yard this round hammers in my gun. This too is max so you would need to work up from 50.5 gr or so.

BTW My 284 is a Defiance Long Sheep Action, Schnieder #3 1:9 28" fluted poloygon, Chambered for 284 that must be neck turned, Jewell 2lb trigger, McMillian Ultralight Edge stock ADL (NOT BDL for weight and stock stiffness reasons). I have titanium rings and bases with a Leupold Mark4. I have many other rifles but in reality this is the only one I really need. 284 is a super round.

They tumbled in a 9.5 twist 7 mag at sea level. Was the first time I seem that happen and was kind of interesting

Re: 168 Barnes lrx in a 9.5 twist?

New here but getting grey hairs over the LRX 168 Barnes in my Rem 700, 280 AI. with a new Shilen, 1 in 9 barrel. although have shot many rounds trying to get it right. It shoots 2 inch groups with 160 Accubonds and the 168 Berger VLD in same point of aim at 200 yds. The LRX has keyholed 3 different sessions on the range with 3 different seating depths. Tried .010, .030 and .050 searching for a place to start tweaking but keyholed each time.
Talked to a Berger Tech and asked me to double check barrel twist. Did that and confirmed 1 in 9 inches. Been reloading since 15 years old and never had a puzzle this hard to figure out. Yes have cleaned and kept copper out so don't start with obvious stuff if you have any suggestions.

Thanks,
Puzzled Farmer in Pa.

Re: 168 Barnes lrx in a 9.5 twist?

I just had an 8twist Krieger threaded into my TRG's.. chambering is for a Lazzeroni Firebird & I'm shooting 168 LRX's in it. Just finished my load actually, and it shoots unreal in that barrel-- this pic was a group at 200 during development.. measures .679" center to center of the two furthest holes (I shot three separate groups like that once I finally pinned down a seating depth*) 168 Barnes lrx in a 9.5 twist?-image.jpg

I had 3/4"-1" groups at 100 earlier on during development, at 3350, but pressured bad. 3275-ish found another node and got groups just like the pic, but (still) one in three shots gave too-sticky bolt lift* Settled for 3200 and just this-mornin' shot 8 rounds (allowing barrel to cool obviously between every 3) all into roughly 2.5" at 400 while verifying drops* Best consecutive shots of my life!! haha.. I am VERY anxious for season to open up in a couple'a weeks!!!

In my opinion, Barnes did a damn good job on those LRX bullets.. it just takes some patience & effort on a "reloaders-part" to dial them in. And possibly a tad faster twist then what is recommended* I'm just a touch below 2000' here at home, and shoot temps anywhere from 30below (celcius) right up to 80F at times.. hunting season however, when I need that thing to perform BEST, is the reason I went with an 8twist over 9.. and I'm glad I did

Hope this'll help answer some "un-knowns" for ya guys having trouble with the LRX's
