IMR 4064 for a 280 Rem?

[tecumseh]

Anyone ever try IMR 4064 in a 280 Rem? I've been working on a load for 160 bullet and my goto powders IMR 4831, IMR 4350 and H4831SC haven't worked out as well as I hoped they would and thought about giving 4064 a shot.

 

[Elkman]

Used it in an 06 with 150 gr bullets for a number of years. Worked fine and was accurate in that rifle.

 

[nvbroncrider]

I think the ticket for a 160 is 7828. If I remember right outta the #3 manual 60 will put you right around 3000. I believe Charlie has used this load to great success.

 

[Polaris]

Worth a try, Hornady lists data, but you probably won't be able to get top velocity with that combo. You might give H414 a try. 4350 is my go-to for all bullet weights in this caliber. With the heavier bullets, tweaking the seating depth has dramatically improved accuracy in some of my loads. What bullet are you working with? I tried everything to get the 160 PT to shoot and couldn't get under 1.5 moa in a rifle that will do considerably better.

 

[FOTIS]

It is ok but nothing to write home about. You're better of using slower powders.

 

[JD338]

54.0 grs IMR 4831 shot .400" for me in a 280 Rem M700 Classic.
I would give RL 19 and RL 22 a try.

IMR4064 wouldn't be my choice for heavy for calibre bullets in the 280 Rem. I can see that it might work well with 139/140 grain bullets, though slower powders will work better still.

 

[Oldtrader3]

I used 58.0 grains of IMR 7828 SSC with the 160 Partition, W-W cases, Fed 215 Match primer. Chrono'ed load at 3009 fps which is faster then the 140 gr load which I used for years. This load convinced me to switch to 160 grain bullets! I can not beat this load by much in the 7mm Rem Mag., even in the 7mm Rem Mag.

 

[tecumseh]

I'm trying some 160 gr Gamekings I've had for a while. I'll get some 7828 from a friend of mine and give that a try.

 

[Oldtrader3]

Work up to it, it is a maximum load.

 

[Mountain Goat]

The 280 is probably my all-time favorite cartridge. For me, IMR4831 was top choice for 140-150gr bullets. IMR7828ssc was fantastic with 160gr bullets, and many handloaders swear by RL22 in the 280. I strongly suggest you give 7828 and RL22 a try next.

Enjoy that 280, for I don't think you can find a better choice for a hunting cartridge when you consider factors like versatility, recoil, and effectiveness of the 7mm bullet, even at extended ranges. There are a lot of cartridges that will do this and more, but not many, if any, that will do it as well as the 280 Remington.

 

[tecumseh]

Work up to it, it is a maximum load.

I will do that! My Sierra manual has load data for 7828. I tried RL 22 last year and didn't get the results I was hoping for.

 

[RiverRider]

I used 4064 in .280 when shooting 100-grain Sierra HPs many years ago. I don't recall the charge weight and I did not have a chronograph in those days, but I remember believing the velocity should have been about 3500 fps. It was the first load I ever got to shoot sub-MOA in my .280 Mountain Rifle. It was fun to shoot jackrabbits with that one.

 

[FOTIS]

For lightweights like that then yes, 4064 will work.

 

[SJB358]

For lightweights like that then yes, 4064 will work.

I had a lot better luck with the 140 Partitions and 55.0 grains of IMR 4350 at about 2950 fps.

Did you .mean 54.0 grs IMR 4350?

[brianwyo]

Max load of IMR 4831 and 160gr Partition works very well for me. Antelope, Deer and Elk in Wyoming hate it. Brian

JD, I meant 55.0 grains of IMR 4350. Sorry for the typo.

 

[Horsethief]

47gn of Varget and Win large rifle primer with the 160gn Sierra Game King gave me a group a little under one inch from a 280 Rem with a new barrel. Chrony avg was 2750fps.
