Thread: An accuracy challenge

Can run up to 2900fps with the 130gr class and RL16 in a 24" Trueflite. Backing them off to about 2750- 2800 tomorrow to test a lower node with 2208. Had a brain fart this morning and used my 123gr load data for the 130gr so the 2208 groups above were way too hot at 2880fps
These Hybrid Bergers are suposed to be less jump sensitive so should find a load pretty quickly tomorrow.


I dragged the 6mm dasher out last weekend for the first time in ages and gave it a run at 1000yds too..

Well that took longer than I hoped.. got a couple of usable loads. The Berger Hybrid Tactical bullets seemed to want to be on the lands or the groups were plagued with flyers.

Finished up with this one and a 4fps ES with 3 duplicate readings of 2818fps.



The Sierra match kings were much easier to tune and run at 2880fps with a higher BC than the Bergers so will probably sway that way once the Bergers are used up.





This has not been a fussy barrel but it definitely seems to favour the 130gr over the 140gr

Well this doesn't meet the original poster's requirements - but most of the post in this discussion don't.

Had to go to the range to retest a scope's zero.
Had some old rounds (loaded 2016 & 2017) for another rifle, same calibre different rifle.
155 gr Lapua Scenars in Lapua Palma cases.

At 100 yards 10 shots in a 1 inch square. Close enough.

Here are 10 - 5 shot groups, stacked on top of each other at 100m...50 rounds through my .223ai whilst forming brass.


I was forming brass and wasn’t shooting for accuracy, but it still confirms that the barrel has some potential and doesn’t shift zero as it warms up.
Of course there had to be that 1 bullet that wouldn’t conform!

Here are a couple of 3 shot groups from my 338 Lapua Improved at 200m, this barrel shot pretty well!





And here’s another 3 shot group from the same 338, cold bore on a 36” x 36” plate at 2003m just to prove that the last 3 shot groups weren’t a fluke.



Ultimately accuracy is subjective and whether a rifle is accurate enough is something only the owner of that rifle can decide on.

I fully appreciate the time, money and understanding that went into those 3 shot groups. Nicely done.

@Matt2308 not bad shooting to break the world record. only for the yanks to change the rules.

Yeh that was unfortunate.
But all good, I broke my personal record and now I just have to do it again officially.

And now, many years later all I do is shoot at paper or steel targets..

Here are a couple of my best ever milsurp groups so far. Both at 100m with military open sights. First is a 4 shot group with a k31 swiss rifle (7.5x55) I was trying an accurising process on the swiss rifles website where you torque the action screws to “tune” your rifle. Turns out it works extremely well! Its most definitely a 3 shot group, the 4th shot either went exactly through the other 3 holes or completely off the target entirely (seems unlikely).

Second is a longbranch No. 4 .303 with the best handload combination I could find on the day. The piece of bark is 1”. Possibly a shade over 1 MOA but I was still pretty amazed none the less.

The half circle shape is great for open sight shooting consistency. Doubt I could manage it with any other target type
