Gentlemen,
Interested in load data using the Barnes 145 LRX in a 280 Ackley. Anyone worked with powders and primer combinations that has shot well willing to share a recipe or two would be greatly appreciated.

Thanks
Dave

57gn of Rel 17 will get you 3040fps in a 22" barrel using a WLR primer on a 54 degree day.

63.5 RL22

CCI 200 or BR4

One hole groups at 100 yds.

Aussie,
Thank you. I have not tried any RE17. Worked off and on today with IMR4831. Got it to settle down and group. Tomorrow morning I'll set up the truth machine (Oehler 35).
I'll put an few together using RE17 tonight and try them tomorrow too.

Ken,
Thank you. Have not tried any RE22 either. 63.5 grains will make a pretty Big Bang. Have you shot it across a chronograph?

Wonder if anyone is using N165. It works awful good with a 140 TTSX.

Dave

The weeks madmoney was spent on 8 lbs of Varget. Next time.

I tried some rl-17 last weekend at got to 59.0 grains with a 140 Accubond. This was near max in my 22" tube and yielded right at 3,200...accuracy was about 1.5 moa at 300 meters. I'm tweaking primers and oal and shooting tomorrow.

64 gr was pretty accurate but 63 was too and offered a little wiggle room for hot days.

Haven't chrono'd; that's coming in next couple of weeks.

N165 was the best powder in my 280AI.

Greg,
Thanks for the heads up on the 140 Accubonds. I have messed with this thing and stumbled on to some interesting data.
I settled on 57.0 grains of IMR4831 using the Barnes 145 LRX's.
I took 40 rounds over to Allegheny Mountain here in Pendleton County, WV and shot plates a week ago last Friday and Saturday.
This load is 3000fps though an Oehler 35 and is 1/2 MOA. Worked great on plates from 250 to 540 yards from field shooting positions shooting level to 20 degrees up and down hill at 8, 10, and 12" wide plates off of my Eberlestock, on a Harris Bipod, and using shooting sticks.
The 145LRX has only two grooves cut in it and even though it has a boat tail that is .250" long it has enough bearing surface that much faster than that in my rifle and it pressures up with IMR 4831. I can shoot a 140 Berger VLD Hunter out of this rifle and use 60 grains of IMR 4831 at 3150fps. Lighter and less bearing surface and it doesn't show any pressure.
Headed to Mongolia in September for Altai and Gobi Ibex so I have settled on a load and am now focusing on putting together some precision ammunition and more practice. I have some 140 Accubonds and will try RE17 as well as N165 and some RE22 although it and N165 are close after hunting this fall.
My go to load in my 6.5/284 with 127LRX's is 50 grains of RE17 at 3050 fps. Thanks for posting your load and thanks to everyone else who posted.
Ordered a pair of Leica Geovid HD-B's last week. Hope to see them Tuesday and get to shake them down next week. They should make dial up a little quicker...
