Guard your stash of Amax's, Projectiles and Reloader 17.........

All gone @Ginga

iirc its 2000 rounds for a dpt

yep, wear and tear is not warranty.

284s were its at. Mine was outdoing 7mm mag performance with 26 inch barrel and the amax. For a point and shoot load the 120 ttsx goes real well too.

Finally got to the range this arvo.

18 inch tube with hardy can.

Main load for getting out there is 162 Hornady Match projectile. Went with these as A-Max are hard to source. Started with ADI minimum load of 50 grains 2209 for 2500 out of the 18 inch tube. Worked up to 54 grain for 2700 which is pretty good for the barrel length. No pressure at all but at 55 there was a slight ejector mark on the case.

At 2700 a 3 shot group were all touching. Haven't measured it but it would be 15 mm or less. Ran the numbers through the computer and validated the drop to 390 yard. Too easy with the CDS.

Gun wasn't fussy at all - Hornday e tips almost touching, reduced load for the boys with 120 ballistic tips were touching at a hundy.

Great job Abe, works like a dream.

Now to find some donks to give it a real trial run.

Cheers

Did shot the Hornady Match as well on my 7mm Mag right after I shot he Amax's, pretty much the same POI and velocities.
Knowing they have different BC's just for a fun targeting shoot I will maybe keep sourcing the Match projectiles and the Amax's for serious game.
I will do some load for my 7-08 with the match pill and see what I can get.
Good stuff, all the best!

Bump from the dead I know, but. What's the case capacity difference between say a tikka 7mm08 with a throat long enough to have the 162amax base seated at the neck junction vs a 284 like @GWH has (base seated at neck junction)??

Edit: I guess it's similar to factory? so 56 for the 08 and 66 284

@Timmy

Sorry finally got round to having a look at this for you.

As per QL, see the usable case capacity as marked in red. This is with the bullets seated in both cases as you described above.

I have had several 284's and 30-284's over the last 40 years or so.
The early ones were on Remington 600's but those actions are really too short to work properly with the 284 case and feeding was problematic.
The last 30-284 was on a rechambered 308 T3 with long mag & bolt stop, excellent gun, accurate plus feed and function were perfect.
At the moment I have a 18" T3 in 308, a new 30-284 Win reamer and a new set of dies.
I want to use Winchester brass rather than neck up 6.5 x 284 Norma or Lapua brass as the Winchester brass measures slightly smaller in the base than the Scandi cases and my reamer was made specifically for 284 Winchester brass.
Anyone with spare 284 brass PM me and I'll likely buy it
Cheers

I'm looking at a T3x in 7mm08 reamed out to 284 or 6.5x55 for long range work (definitely sub 1000 yards, more like 600-750m max), Has anyone thats reamed a Tikka to 284 got some feedback on whether they would do it again?
I've used the 162 Amax on a few reds and it absolutely sacked them so I feel confident with that pill (was launched from a 7mmRM)

I love my T3 284. 17" barrel pushing 162 amax very accurately at 2740 fps. Holds 1000 ft-lbs to 850 yards. I run a DPT magnum can, its quiet and easy to shoot well, and only same overall length as a 21 inch barrel. Its the one im reaching for in the safe all the time now.

Dropping my T3 and new 7-08 barrel with Dave Ward today for barrel swap and reaming to .284.

Will be a few weeks before I bed it and get into load development, but will let you know how it turns out.
