Anyone with a .284 Win tried N140,

Hi Guys,

Not sure if many here use one! But,


Has anyone has tried N140, N150 or N160 in straight .284?

Its primarily to be used as a deer rifle utilising 140gr heads. But would also like to try some long range so im also wanting to shoot 168gr Berger vld's for the odd bit of long range target.

The rifle is built on a short action with a 24" barrel, hence the 168gr over 180gr.

Thanks in advance,
Joe
 
I have a Winchester 100 semi auto in .284 Win (in Germany) but the S&B scope I had bought and ordered to fit on Apel on swing off mounts was put on wrongly by the gunsmith and all the rounds are hitting totally off the target (he had no ammo available to test it after his work) now I have sourced some rounds for him so I hope to begin loading for it in late summer so I will watch this thread with interest.

I use VV N-160 in my 7x64 and .280 Remington to power the 160-gr Sierra SPBT and HPBT Gamekings with super accuracy. I have not tried N-150 in them. Based on the difference in case capacity, I bet starting at 50.0 grains and working up to 54.5 MAX would probably get you 2,625 to 2,800 FPS out of a 160-gr bullet, and backing off a grain will probably be close with the 168-gr with that 24-inch barrel. It will probably get you the most velocity with 140 gr and 150 gr, but VV N-150 is probably a better powder for the case volume and the shorter, stubbier case. Personally, I find that the 160-gr Sierras and Hornady 162-gr SST are as heavy as I want to go, and have super BCs, very flat and accurate.

I had saved this article off last year for comparison with my .280 Remington. It is one fellow, extensively testing a bunch of powders in his two .284 Winchester rifles, one a carbine, and one a longer barrel. He found VV N-150 to be the most accurate for him with 120, 140 and 150-gr bullets. I would start there, 140-gr and 150-gr, and with standard Sierra Gamekings, before spending any money on "premium" bullets. If you can get some RL-15 or RL-17, try that. My 7mms all like the Hornady 154-gr.

Loading the .284 Winchester for Accuracy
His experimental methods are very logical and thorough, as he dials one factor at a time, and very quickly stops with what will not work.

N-140 is not going to give good velocity... too fast, so the pressure spike will prevent loading enough powder in the case.

I use N160 in my 284. 162 amax lapua cases, 54grn N160 Fed primers. It will do 1/2 moa

I also shoot a 6.5-284 140 amax lapua cases 50grn n160 fed primmers. 1/2 moa

Ive tried reloader 17 but wasnt so good

H4831sc was good in 284
 
So, for those that are interested.


I went with N160. looking promising so far for those interested.


Currently at 52 grains of N160 with a Fed210 primer under Hornady 162gr Amax. OAL on this is 3.075 which is as long as i can go and still eject a live round, dont really want to longer as this is a hunting rifle primarily. anyway jump to lands is .102, best group ctc .214 (3 shot group, will go to 5 shot at some point)


Also doing some testing with 140gr Berger VLD hunting. Current load on this is 53gr N160 with an OAL of 3.035. Giving .130 jump to the lands! i ended up at this as i put them through the seating die with out adjust it after seating some Amax! Anyway, this printed a group of .124 CTC!! again only 3 shots though.



No signs of pressure on any of the cases.

Shots all taken at 100 yds, bipod up front with a sand sock at the back, off the bonnet of the 90. Scope is a Simmons 2.5-10x50 WTC.
Next step is to see how they do with 5 shot groups and then move the target further away.


I may also increase the charge weight to see when pressure signs start. i dont have a chrono so not 100% on velocities.

168 HPBT Sierra .488 N-160 44.3 2300 54.3 2800


This is from load data direct from Vihta vouri. It seems largely consistent with Sierra load data that i found.

Also this has proved insightful http://home.earthlink.net/~rfrailey/sitebuildercontent/sitebuilderfiles/284loaddata.pdf


Also i am neck turning to suit my rifle, so far i have not suffered from the dreaded doughnut that seems all to common with necked up Lapua 6.5 - 284 brass.




Hope this is helpful to those interested.

I have just had a .284 long action with a 28" Bartlien barrel built. It is going to serve long range (1000yd) driving Berger Hybrid and shorter range hunting for large deer/moose with 162/180's. I have yet to fire her, awaiting a range day, Brass prep is all but complete. Looking to start at 149 Gn of Vhit N560 (double base), working up to the node before pressure signs, so will probably achieve around 2850 I hope. Also going to use Reloader Swiss RS 60 as a sub for RL17. The best powder by all accounts is H4831SC, but as Britain doesn't get this anymore its out!
If anyone is interested I will PM results as I go, though this will be a slow process, as got the bit of work before I get "the round" A bit of fun to go yet!

i would advise against starting at 149 gn of vit n560.lol
 
With a 28-inch barrel, have you considered staying away from a hot double base powder like N560, and trying something like Reloader 19 and 22, IMR-7828ssc, and Hybrid 100V? Maybe even Magpro. Can you get those?
 
i use IMR4350 in my .284 with a 168gn sierra match king to shoot f class out to 1000yds.
other powders that will work well with the .284 case are h4831sc-n160- swissRS70.
