.284 Winchester Handloads?

[samuel_284Win]

I have a .284 Winchester that my grandfather gifted me which he built years ago. My grandfather was a machinist, tool and die maker. Used to run an old-school lathe and very gifted with precision. He has since passed so I want to honor his memory and keep using the rifle. The rifle is built off a Mauser action and has a 24-inch barrel. Unsure on barrel twist rate. The chamber is quite long, given that standard .284 COAL is 2.8 inch while a COAL that touches the lands is 3.17 inch. Finding .284 Win factory ammo is essentially impossible. I have plenty of once-fired brass.

Curious if anyone here on HT has experience with a .284 Win and would be interested in hearing how you are reloading for your 284 Win. Wanting to know bullet, bullet weight, powder, powder charge, seating depth, etc...

I have no advice but the cartridge intrigues me. Good luck on your search.

I built a .284 a few years ago. It rapidly became my favorite hunting rifle. The 2 best powders I've found are VV N150 and RL15. Varget isn't bad. N150 is spectacular with bullets in the 140gn range and RL15 for 150gn pills. You'll hear people talk about IMR4350, but I've never gotten better than mediocre results from that. If I had to choose just one powder for mine, it would certainly be N150. That said, I shot an elk and a deer last fall with a 150gn Accubond pushed by RL15. Very accurate and moving about 2900fps.

.284 Win is an awesome cartridge. You're going to love it.

I run the 140gr Accubond using H4350 seated .060 of the lands. My velocity is around 2930fps with 53gr of powder. PLEASE work up for your rifle. My rifle shoots 1/2MOA all day. Works magic on SC Whitetail deer!

26" Barrel with 1:9twist

I run the Remmington 9 1/2 Magnum primer, not needed but I run it in about everything.

No advice to give but man that's awesome. I haven't thought a lot about doing a .284

What your barrel length? SA or LA, are you running a spec chamber or custom? Thanks.

Probably a lot of overlap, but be careful using 280 Remington recipes for 284 Winchester.

I missed the Winchester part, thanks

The 284 likes H4831sc, about 54 grains, about any 180gr class bullets, if the twist rate is fast enough (1-9 or faster). Have shot thousands of rounds of this for F class and hunting and it was, up until the last two years, the go to round for F class 1000 yard shooting. Seat your bullets to the length your chamber shoots them best, but somewhere around .020" jump is a good starting point to figure this out. CCI BR2 have always been my go to primers for the 284. Take a tight patch, mark your cleaning rod near the handle and one at the muzzle, push it down the barrel until the mark near the handle makes one full revolution and then mark it again at the muzzle. remove the rod, measure the distance between the two marks by the muzzle and that is your twist rate.

I think @Frequently Banned Troll or one of his buddies has a pretty good 162 gr load.

 

[Frequently Banned Troll]

This is what I got - Hornady brass and 162 amax.. 53.7 grains of H4350. Gives 2950 in that barrel with a really mild load. Jumping about 15 thousandths

Mine is a 23" carbon fiber wrapped barrel on a short action Savage 110 Ultralite receiver. The chamber is standard SAAMI specs.
