Thread: .284

I have a 7mm08 that I had Grant at True-Flite ream to .284 and shorten to 16"s, shoot very well 162gn at 2750fps and 140gnABonds at 2900fps both loads are at max with RL17. Could find another powder to come close and primer selection was also important, the 162gn load preferred CCI primers less pressure the 140gnABs didn't make much difference. Grant also sold us a old 6.5x55 Tikka barrel he wanted to get rid of, reamed to 6.5x284 16" barrel, this is starting to be my favorite combo 140gn A-max at 2750fps 130gnABs at 2800fps. All my loads were from Greg Duleys writeup he did in NZHUNTER.
Shot it at 600yds a couple of weeks ago on steel managed 5 shot 4" group - rapped(haven't shot the .284 since load development as still waiting for shipment of the 162gnA-maxs). Shot my first deer with this combo last weekend.
I have a DPT suppressor fitted to both barrels, after about 200rnds the first baffle is starting to erode quite badly the others looking like new. A new baffle to replace is only $45 to me not a issue really when you have such a light compact and accurate rifle. My next step is to maybe flute the barrel and bolt.

What powder are you using in your 6.5-284 as I have a Tikka the same with 20" barrel I want to use 130 grn ABs

RL17 tried 6 other powders nothing close in the 16" barrel wouldn't shoot any of the solid copper bullets either.

Thanks any idea on Vol with 130grn

I thought those dpt have a lifetime warranty?? Surely if the baffles are stuffed after only 200 rounds it should be replaced for free under warranty. No way should you have to pay to replace manufacturers faults. That's what warranty is for.

If you buy an alloy moderator, and use a medium capacity plus centre fire cartridge, you'll start eroding the first baffle from the first shot..

It aint something that a manufacturer can change. Insert some steel, titanium and it'll last longer. If you want 195gr cans, you pay the penalty..

It should last 500 rounds, before replacement of the module..

As I'm sure has been pointed out before, the problem with modular suppressors is you can take them apart.

All suppressors with alloy internals suffer from erosion.

The shorter the barrel (bush pig), the bigger the case, the more the pressure, the greater the heat, the lighter the suppressor, the worse it is.

If you can't take it apart & see it happening you can't get stressed about it.

No manufacturer in his right mind would offer a lifetime guarantee when every tom, dick and harry fire a variety of projectiles, some at absolutely insane loads down a can. DPT offers replacement baffles at a reasonable price, doubt you'd need to replace anything other than the first one. Also, if you're going to be firing high volume, a light weight modular can is probably not the best option.

Quote from their ad in NZ Guns magazine: " DPT suppressors come with a lifetime warranty ".

That ad has been running for a year or more, so it is reasonable to assume that anyone who has purchased one of those suppressors has the right to expect a lifetime warranty to be honoured.

I have a t3 284 , had Abe ream out a t3 7mm08 fit a long action mag and bolt stop, shorten the barrel to 19" and fit a second hand, barely used Hardy 7mm gen 4 magnum can. Im shooting the 150 LR Accubonds at 2960 with a mild load of R17 hot load pressure was 3gr higher . Shoots well .4 most days.

Where are you sourcing your 150 LR Accubonds from? Hard to find....

Hi Jasec, I got tui_man2 to get them for me, he might have a few left, might pay to PM him.

A life time warranty is for machining and component quality not for abuse of the product, which I believe I'm doing with a 16" barrel and max loads probably 65000psi loads. The product is top quality lightweight, works bloody well and it's priced very well. My .223 DPT is like new inside and fired thousands of rounds. Come on get real.
