6.5 PRC 153.5 grn Berger for 1000yds and 1 mile.

kdrogers71775 · Nov 13, 2023

Been working with this load for a while.
Powder: VV N565
Charge:58 grains
Primer:CCI #34
Brass: Hornady (its all i have)

Rifle
Ruger hawkeye target in MDT chassis.
Optics: U.S. Optics FDN 25X

Current velocity is around 3050 fps.
Berger stability calculator says i should be stable.

However....at 1 mile?..... with 1:8" twist. Will my bullet spin enough RPM to hold true at 1760yds.
1000yds has been very consistent.

1/2" groups at 100yds consistently.

Thanks everyone.

You'll have to shoot it and see what kind of correction you need.

I shoot that bullet in my Creed at 2550 'ish and it's stable out that far with a 7.5 twist. I can't imagine it wouldn't be with yours at that speed.

Really wish Ruger would start using the 7.5" twist for the 6.5 PRC. Alot of people doing rebarrels with that rate.

From my understanding, gyroscopic stability will only increase down range, as fps decays faster than rpm, so that should be no issue.

At sea level, JBM ballistics does suggest you'll be pretty close to the super/sub sonic transition at 1760 yards, which could have some unwanted effects, though it appears you'll still be above mach 1 unless your shooting on a cold day.

Just for perspective, a 1 mph wind is good for 20" of drift at a mile...better get those wind calls right on...

Wow.
Shooting at a target a mile away is mind blowing.
Will be following this with interest.
Good luck.

20" drift is honestly not as bad as i expected. Some of the guys shooting.308 at 1000yd get almost that much. Wow

that's 20" per mph of wind. meaning that a wind change (pickup or let off) of 1 mph will move your impact 20"

Oh gosh. Thats HUGE

I've shot at a mile with 147 ELDM's.
Their BC is almost identical to the 153.5's. They're getting pretty sketchy at a mile. I'm not real impressed by them even at 1200 yards. My 30 cal 245 grain bullets have become my go to for those longer ranges.

BrentM · Dec 6, 2023

I've only played with them a little and wound up back at the 153 a tip. In fact right now
I've been running the 135 a tip for shots to a mile but mostly around 1500 and less. I've been very happy with the performance. You might consider the 147 and 153 hornady as options.

I run a berger 144 hybrid target in 6.5x284 the 147's gave to much SD which prints vertically . Retumbo and H1000. The berger 153 is to long and takes up to much room for the powder to push it fast enough
to take advantage of the higher BC , in that case Capacity The PRC is same way.
if i ever find RL 26 i will try the 153 again.
i'm at 5000 ft elevation so im super sonic to the mile ,so its a lil easier ,without worrying about stability issues through trans sonic .
i would like to push to 2000 yrds someday. But a mile is all the room i have on my range . Ihave a couple of 260 rem but they are set up for hunting and not really an extreme range tool.
i have never tried the Atips

kdrogers71775 · Dec 6, 2023

N565 has far exceeded RL26 in my 6.5PRC. They say N568 and N570 are possibly even better but i havent tried them yet. N565 gave me 150-200 fps more than RL26. N565 has brought my rifle to life. Finally

dug · Dec 6, 2023

What is your % case capacity with n565 ?
i dont really use that brand of powder
