Home Forums Hunting & Shooting Ask The Gunwriters 284 win

Reason I asked was that I have two older Tikka's that both have quite long throats.
I load both out to close to the leade and they still function fine thru the clips.
In both of them to get up to published max velocities I have to go at least 3 more grains of powder with zero pressure signs.

I really like my 284 in a Savage 99 as well. With 150 Partitions it will do about anything I want out to 300 yards and print 4" groups or better. I match 7-08 ballistics at lower pressures in deference to the rear lock up. Nothing wrong with that! Cool factor is there. Flat in the scabbard. What's not to like.

I also have two 6.5 Rem Mags and a 350 Rem Mag in 60's original carbines. The 1960 era short magnums...So far ahead of their time that they were criticized to oblivion. Some people still don't get em.

Many gun writers of the 60's never did get either the .284 or the 6.5 and .350 Remingtons. They kept insisting all would be much better rounds if made on longer actions, where the bullets could be seated "out where they should be."

The .284 and 6.5 were both designed to provide .270 Winchester ballistics in a short action. They did this, so there was no reason for them to be built on a long action. Same deal with the .350 Remington, a short-action .35 Whelen.

Anyone who has a Model 70 Short action 284 win would tell you that you have plenty of room (3.100") to take full advantage of the cartridge's capabilities. I agreee with SU35 on the 200fps, and Hodgdon agrees also (well almost). With 139 gr bullets, 2906 fps is the fastest 7-08 velocity listed on their site (H4350). The 284 win lists 3079 fps for the same bullet, and like SU35, I easily reach 3100-3120 fps with RL-17, using 140 gr TTSX and a longer COL. The Hodgdon numbers for the 284 win use COLs as long as 2.970" in their loads, and they are all within SAAMI limits for pressure. You should obviously not use these same loads unless you are able to seat your bullets to the listed lengths. I have two 7-08, Rem-700s and one 284 win Model 70. In a bolt action rifle, there is a definite step up IMO with a 284 win. But with today's bullets and powders, both are great guns and adequate for any hunting I will probably ever do. I prefer the 284 win slightly.

Welcome Bobby....sounds like you like the 7`s. So do I. Lots of good info here for you to digest, and lots of the talk boils down to what one will do that the other will not. Years ago I built a 7x57AI on a Mauser action, and my brother built a 284. When it came to killing deer sized game, we couldn`t see any difference in performance between the two. Just a matter of choice. I always wanted more snort from the 7`s tho, Maybe you will too? so I finally went to a 7 Wby. If I were to do it all over again, I would start with the 7 Mags. Your gonna handload for whatever you do, the big 7`s give you more options, for whatever you want to do, IMHO.

Another FClass shooter with RL17 and the new Berger Hybrid 180 bullets. I do think they are finding RL17 quite a bit faster, but not as accurate.



I also have 500 of the 180 Hybrids will be testing them this weekend in my 284 shehane. with RL - 17 . Will keep you up to date .
My report, lets start with 30" 1-9 Bartlein 1.250 7mm .277x .284 4 groove stolle panda f- class action
robertson stock , all bullets @ 20 thou in lands all primers large rifle KVB -7
cloudy 88 degrees 75% humid. hot and sticky. ( dallas )
54.7 2996,2988,2991 = 8 es .216 group ( all 3 shot groups)
55.0 3012,3014,2998 =16 es in the .400
55.3 3021,3015,3025 =10 es in the .400
55.6 3046,3047,3055 =9 es in the .400
55.9 3058,3051,3056 =7 es .202 ( best group) about max for 90 degrees
56.2 3073,3082,3058 = 24 es in the .400 last one looks funny action hard, primers bad
56.5 3094,3083,3100 =17 es in the .400 ( action hard to pull up primer bad )
Will start the bullet seating adjusting now with my 2 nods loads 54.7 , 55.9 and 5 shot groups

Excellent Butch,

I like this load.

55.9 3058,3051,3056 =7 es .202 ( best group) about max for 90 degrees

Figure 200 fps off for a 24" barrel

Look forward to your reports.

Still scrapping for dough but I did order some 284 brass.Thanks for all the input. Bobby
