DRT Terminal shock results on game

[z987k]

They pulled the listing for the 79s. Can't find them on the site period. Did you hear anything from them? Last I heard they said they'd have some in a few months about 1-2 months ago. I hope they didn't quit selling just the projectiles!

I asked and they said probably next week, but the 152gr 277 is probably done for due to low demand.

Has anyone shot game at the listed minimum impact velocity of 1800fps? Just wondering if this bullet needs a “safety factor” like mono bullets needing 2100-2000.

I have not had an impact at that low of velocity. This bullet is nothing like a mono. It acts more like a cup and core. It more or less is.

The 135g was highly destructive at 2k fps. Complete fragmentation. At 1800 maybe you get a longer neck length (as long as they upset consistently). Too small of a sample size to say for sure, but I certainly wouldn't hesitate at or a bit below 2k.

Appreciate the info, based on my 6.5cm load data it would be at 1800fps around 550yds. Makes for a good load for everything I need so long as the bullet does expand/upset at that velocity, and I shoot straight in that situation…

That is a big nasty looking boar!!

A big pig like that can be fairly tough to kill and pretty critical on shot placement. Good test media IMO.

What is the load you are using?

44.5 gr of staball 6.5 in a 6.5cm tikka 24”. Shoots a 1” 10 shot group. I ran out of bullets to estimate velocity(no crono), but based on the load data I should be just over 2800fps.

Lapua LRP with Remington 9 1/2 LRP.

COAL? I have seen folks running from 2.715 to 2.775. Curious where you landed.

My CBTO was 2.2475. Unsure about COAL but can let you know when I get more bullets

 

[philcox]

I can guess off that.

@Quercus what is your load for your 135? What cartridge?

Also, did you ever get the 79, and work up a load?

6.5cm, 42gr H4350 in Lapua SRP, boat-tail at the neck/shoulder. You could probably get more velocity or smaller groups out of it. I just use that load because it shoots adequately and happens to overlap with my 140gr ELD-M zero so I don't have to touch the scope for out of state hunts or practice.

Never got ahold of any 79gr. I think they might have discontinued them, as they're not on the website anymore.

79g DRT projectiles are back in stock. Along with the 6mm and 6.5 mm bullets fyi

Which primers did you go with? Std, Magnum, or BR?

Federal GM205M. Take that with a grain of salt though--I just used what I had on hand to load several hundred rounds a couple years ago. Didn't tinker with weights or components. You may do just as well with LRP and loading them hotter.
