swagger Posted June 13, 2015 Report Share Posted June 13, 2015 Hi Guys, Has anyone tried any of the above powders in a 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. The rifle is built on a short action with a 24" barrel, hence the 168gr over 180gr. Thanks in advance, Joe Link to comment Share on other sites More sharing options...
dannywayoflife Posted June 13, 2015 Report Share Posted June 13, 2015 Would think that's too fast a powder for the 284. Link to comment Share on other sites More sharing options...
swagger Posted June 13, 2015 Author Report Share Posted June 13, 2015 I thought N140 probably to fast for sure but recently read an article on loading .284 and it basically said that N150 works great for 120gr upto 150gr. And that N160 was a close second. the author tried 49 different powders across 4-5 rifles to come to this conclusion. Just wondered if anyone here had had tried any of them as i have N140 on hand and can easily get hold of the other 2 with out worry about supply issues.

dannywayoflife Posted June 14, 2015 Report Share Posted June 14, 2015 Ive never owned or loaded for a 284 but would think there's better powders than N140. Do you have quick load? Link to comment Share on other sites More sharing options...

Nocrimp Posted June 16, 2015 Report Share Posted June 16, 2015 I use the 180 grain Berger hybrid with Elcho 17 (RS 60) or to keep under the High Muzzle Energy limit, then it's N150. If you're going to try 168gn bullets, I would expect that you'll quickly find an N150 load that will be very accurate with manageable recoil. As ever, work up slowly looking for signs of pressure.

swagger Posted June 16, 2015 Author Report Share Posted June 16, 2015 Thanks nocrimp. Doesn't seem that many people are using viht in their .284's! I could just go down the h4350 or h4831 route but would hate to develop a sweet load only to be able to source the powder and have to start from scratch. Incidentally the link a couple of post back is to the article that got me thinking of going down the viht route. Joe Link to comment Share on other sites More sharing options...
Nocrimp Posted June 17, 2015 Report Share Posted June 17, 2015 I reckon N150 will serve you well. If you need extra velocity you'll need to opt for a double base powder but your barrel life will obviously reduce significantly. Seating depth will make a big differenct to pressure so use quickload to indicate starting loads and work up from there. Let me klnow how you get on... I am a big fan of the 284Win.

swagger Posted June 17, 2015 Author Report Share Posted June 17, 2015 Well ive finally managed to sort some 140gr bergers. hopefully ill get round to picking up some powder at the weekend. Im gonna start out with N150. i havent been able to find much info really. i hoping to get to around the 2800fps mark with the 140's ill post up as i make progress, anyone feel free to chime in with any knowledge!! thanks again, Joe Link to comment Share on other sites More sharing options...

I would of thought the 180 bergers to be well under hme, I know 300wm is hme but thats burning alot more powder, I would like the hme explained in figures to where and what the limit is if possible, regards swaro Link to comment Share on other sites More sharing options...

Nocrimp Posted June 30, 2015 Report Share Posted June 30, 2015 Look here: http://www.westatholl.org.uk/WebPageStuff/HME/HME.html You'll see that the HME limit for a 180 grain bullet is 2882 feet per second In my 284 win, using RL / Elcho 17 powder, I can easily go over this HME limit.

swagger Posted July 12, 2015 Author Report Share Posted July 12, 2015 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. Also found this: 284 Winchester Bullet BC Powder Start FPS MAXIMUM FPS 100 HP Hornady .279 N-140 43.9 2900 51.1 3300 120 V Max Hornady .365 N-140 37.7 2500 48.1 3000 139 SST Hornady .486 N-140 37.1 2400 45.3 2800 154 SST Hornady .530 N-140 34.6 2200 43.0 2600 162 SST Hornady .550 N-160 39.6 2200 48.3 2600 175 SP Hornady .462 N-160 38.3 2100 47.1 2500 284 Winchester Bullet BC Powder Start FPS MAXIMUM FPS 100 HP Sierra .209 N-140 47.5 3000 53.5 3400 120 SPT Sierra .328 N-140 45.9 2800 49.1 3000 130 HPBT Sierra .395 N-140 43.7 2700 47.3 2900 140 SBT Sierra .416 N-140 41.0 2500 46.7 2800 150 SBT Sierra .483 N-140 39.8 2400 44.5 2700 160 SBT Sierra .455 N-160 43.9 2300 53.4 2800 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. Joe Link to comment Share on other sites More sharing options...
