284 win build w 195 berger

A handloader can go nutty with this stuff. I haven't tried it but it might be fun to try the 230 in a 30 BR. Problem is the load data. Uncharted waters to be sure.

That long 203 would look funny. I may just carry one around in my pocket to show the newbies at the range.

As for getting a reamer. I have used Pacific Tool and Gauge for all my reamers, so has my friend Dan. I have called Dave to discuss the details and have never been disappointed. We make up a dummy round and have some notes sent with it for them. We have 19 reamers between us.

As for the 284 reamer... Both Dan and I have our own 284 Win reamers. Mine is setup for a 3.050" mag box with 168 VLDs to be able to engage the lands. I have a ton of 284 Winchester brass so I opted to turn them as this brass is notorious for having irregular thickness necks. I ordered a .315 chamber neck. Dan's reamer is for a LA with 180 hybrids so he can also make contact with lands. He is using 6.5-284 lapua brass. This part of the puzzle is always interesting.

Plenty to read on the 284 subject. Hope you enjoy making this package perfect for you.
 
I had at one time 1000 new 284 cases, and sold them. Wish id kept them now!

For a 315 neck, what are you turning the neck thickness to?

284 win seems to be a great round for those concerned with maximizing barrel life...kind of a sweet spot for performance and barrel life.

If it were possible to create sabot rounds as accurate as regular bullets that would go a long way towards barrel life. Imagine for instance a medium 338 case driving a saboted 195 hybrid at 3100 fps. With the right sabot material, the throat erosion would be less, youd have less pressure and thus heat checking than you would get from a case like a 28 nosler you would normally need to get those velocities.

I suspect it would have accuracy issues though with non fin stabilized projectiles.
 
AZ so are your reamers different? I hear if you use 284 win brass you need a standard 284 reamer, but if you use 6.5-284 norma brass you need a reamer for 284 norma... the base of the norma brass is like .503 vs like .499-.500 284 win. have heard of people using 284 win brass in a 284 norma chamber and as a result the brass expands and primer pockets loosen up.

What is your take on this? I would rather use the lapua brass, so it seems I have to neck up 6.5-284.
I still searching for a 30-32 inch 1:8.0 twist 7mm barrel also.
Is it best to buy re sizing dies, re-size 6.5-285 brass in a 284 die, and then send in a few cases (with bullet) to have a reamer that is close to the size of you re-size die? your take..
 
I have the Pacific Tool and Gauge reamer prints in front of me. They are the 6mm-284 and the 284 win

Both prints show .501" for the base of the cartridge

------------------------------------------------------------------------------------------

I measured a few pieces of norma 6.5-284, Lapua 6.5-284 and 284 win at widest location:

The 284 win is .500" and the other two are .501"

I was able to place all three into my rifle's 284 win chamber with no effort.


Nosler's reloading guide shows .500" for the 6.5-284 Norma. Some prints I have found show .501" as the case head dimension.

Unfortunately Nosler doesn't show the same dimension on their print for the 284 win but every print I have found on line shows .500" .Only exception was Accurate shooter's site which shows 5.008" which is repeated on the norma 284 brass link below.

I think it was mentioned earlier....Norma now makes the 284 win case for Bullets.com.

Norma to Make 6mm Dasher and .284 Win Brass for Bullets.com « Daily Bulletin

Based on what was stated you might want to consider using the new norma brass. They say theyu are taking extra steps to ensure tight primer pockets and very uniform wall thicknesses. This is something the original 284 win suffers.

I would ask Bullets.com about the brass specs and also your reamer maker.
 
Guys--- thanks! for the helpful input, from what I was reading the BRASS is different, .500 for normal and lapua 6.5-284 brass, and .495 fpr 284 win, a chamber cut to 500-501 would be a good choice for me I think. The smith I was talking to does not have a reamer that is long enough, and he doesn't like to use throaters, so I have to have Pacifc tools make me a reamer. About how long does it take for them to complete the reamer and send one to you?

I'll have a 3-5 month wait to get my smith to do the work after I give him the parts. accurize the 700 action, ream install barrel and brake.

on barrels.. I am looking at a 7mm 8 twist 31 inch heavy varmint contour blank, and a 32 inch strait taper 1.25 x 1.25 inch. Smith thinks maybe the later could put some stress on receiver. tell me long barrels over 28 inches don't give much fps gain anyways. said it might be good idea to bed a couple inches of barrel past receiver if I chose that route.

what is your take on long strait 1.25 x 1.25 in barrels on 700 action?

Here are the European CIP spec sheets for .284 Win and 6.5-.284 Norma.
The diameter R1 is equal.

Thanks for sending that. I've tried to get into CIP site and I got little info on dates etc but not spec. There is little different in L1 MAXI/MINI and case head F and B. It was nice to see they had 6ppc as SAAMI and 6ppc USA as Sweden CIP.

You may want to read this and it may explain about actions/barrel weight

Record-Setting .284 Win F-Classer
 
Yes bushing die .309" I have separate Redding body and neck bushing dies for the 284 which also doubles as for the 6mm-284. I simply switch to a different bushing for the 6mm. I also use a Redding 284 win competition seating die for both cartridges. I didn't think it would work with the 6mm-284 but it does.

The 284 is used as a hunting rifle so I always use the body die to ensure there is no resistance when closing the bolt. It feeds and ejects smoothly and easily.
 
Again thanks AZ. also what die is best for necking up 6.5-284 to 284?What I mean the Redding bushing die only compresses the neck. Do you use a normal die that has a center mandrel? if so what is a good brand.
It appears the dies are going to run me over $300.

On the reamers to be made. do you have to have a print made up? or can you send brass with bullet seated in it and have em make it off of that?
 
I suppose you can neck up the 6.5-284 lapua brass. I would use a K and M tapered mandrel. I had used their products and like them.

Not sure you need to go to this effort. Did you open the link with the video?

The owner of Bullets.com had Norma make some 284 brass to his specifications. I would seriously consider using it instead. Give them a call.

Quite frankly if I were to require new 284 brass I would buy Bullets.com's norma brass.

Shop the Norma 284W-100 - .284 Winchester Brass Cases, 100 Count at Bullets.com

Repeat from earlier post:
