Sounds like they are stabilizing at those velocities as I believe that bullets become more stable the further out they go. Thanks for posting up the results

Re: 168 Barnes lrx in a 9.5 twist?

I love the LRX bullet. Hit this mule deer at 287 yards with a 175 gr LRX out of a Lazzeroni Patriot. The deer was down and dead before I could find it in my scope after pulling the trigger. Never moved. I believe my barrel is a 1:12 on that rifle but it is a .30 cal bullet. The .284's are longer and skinnier so I could see how you would need a tighter twist. I have a .284 Win that I am going to try the 168 gr LRX in. It is a 1:9 twist. That gun is dialed in for 180 Berger VLDs but with the impressive performance of the LRX I am going to work up a load with R17 and hopefully take it on a Colorado Elk hunt I have scheduled in October. I'll try to update you on my findings.

My guess on W3P .308 230 Grain Bullet: G1 .740-.755

Re: 168 Barnes lrx in a 9.5 twist?

Well, I finally got a good enough day to go out! Hit the range early (830) to avoid the inevitable wind at 10, and the heat! It was only about 80 at the range, and about 85 or so when I left. Anyway, here's the 168 LRX info
Sendero 7mm STW. New/prepped remington brass, 9 1/2M primers, retumbo. Loaded to mag length 3.650 overall
Started low because I couldn't find very much reliable info for retumbo in an STW..... first several rounds were sighting in the scope, as this combo is new to me. Rough sighted in 3 rounds!!!!!
76.5 grains-avg 2992.9 ES 23.5
77.0 grains-avg 2989 ES 14.5
77.5 grains-avg 3021.2 ES 11.4
WTF is up with the drop in velocity on the 77grain string? Consistency was okay, these three produced about 1 inch groups at 100yds. 77.5 grain string had first and third shots almost touching, and second one flew about 3/4 inch. Love the low ES, but I'm not counting on these results alot as the brass hasn't been fireformed yet. My next groupings will be 78, 78.5, 79, 79.5, 80, and 80.5. on my next days off if the wind will cooperate!
Reloadersnest shows an unverified load of 82 grains of Retumbo behind a 160 grain TSX at 3306fps. So I am kindof using that as the neighborhood of where I am hoping to be at. I'll keep an eye out for pressure signs at 80 and above.

Weather hasn't been good here to sight in the new scope/do load development (10-20 mph winds on my days off!!!) I have 20 rounds with this loaded up waiting for the weather to clear.

Its the other way around. The higher in elevation you go the less need for a faster twist you will have. Above 5000' a 1-9.25 will be fine. My Rem700 STW shoots 180 Bergers and 168 LRX just fine at 5600'. Both are sub MOA.

gunner69, how did your elk hunt go? I am also building a 284 win to shoot these bullets, it will be a lightweight deer/antelope and elk rifle.
