Signs of accuracy confirmed

[Wreck-n-Crew]

Its been a while since i posted on my rifle build and today i confirmed my final load. My previous post found here https://www.thehighroad.org/index.php?threads/signs-of-accuracy-new-shilen-barrel.887540/

As it turns out my build is very accurate. More accurate than i am on most days. The surprising part is the bullets which happen to be Barnes Matchburner 140 gr and to be honest and i went with Hornady brass rather than my tried and true Peterson mostly because of the shortage. I guess what matters most is results.

So far i have seen nothing but accuracy. I feel i am blessed to have the components i do have and to be honest i did not expect this much accuracy from a barnes bullet but its definitely proven itself worthy.

What has not proven itself worthy is me and a bipod. I just shoot so much better with bags or bag rest combo.


Enough chitchat how about some results? Well today i managed a .254” group with a load i have tested 2 prior times and on my worst day it was .44” @100yds. With an SD 5 and ES of 11 over 15 rounds i think i can lock it in and plan my trip to ThunderValley for some 1,000 yard plinking.

very nice shooting!

i'm guessing you have your SD and ES numbers backwards though

Yes i did. Lol. Ill correct that.

How are you shooting, prone or bench?
I like a bipod and rear bag on the ground, I prefer bags front and back on the bench.

i will be shooting prone when i Go to the 1,000 yard range. Testing done on bench.

The bipod i do have is nothing to write home about. Though it might work okay on the ground it definitely is not ideal on a wood bench with nothing to load against. Not to mention rubber feet and nothing to load up against.

I think i prefer a rest with a bag on a bench because its adjustable. But two bags get my best results.

at some going i am going to need a good bipod.

as for this trip i wont be using it.

I found that the match burners worked great for me with Hornady Brass. I haven't seen H4350 since forever, so I used AA2700 just because it's what I had. It worked great. Glad you found something that works for you.

Please report back after your 1000 yard weekend, good shooting to you and thanks for posting.

the gun is probably bouncing on that wood. put a t-shirt between the bipod legs and the table to allow the feet to slide.

luck,

It would. Its not ideal for wood for sure and i don't think its really suited for grass either. Its something you pop on an ar15 for plinking maybe . My bags are my go to on this one.

 

[murf]

a couple smooth pieces of plastic will work better in the grass.

bags are a good choice for quarter minute groups.

Correction on the group size. It was closer to .293”.

I must have made an error when using my calculator. I mean looking at the group you can see that there was at least a bullet width between the top right and bottom left.

Looks good. What stock is that?

 

[WrongHanded]

Wow! That's awesome.

The only way I can get groups that small is by poking the holes in the target with a #2 pencil. If you guys ever see me posting sub MOA groups, forget I said that.

I have found the 6.5 CM to be very easy to load for. I had a bunch of factory Hornady 140 ELD-M so when I shot those up I just used that brass. I had read that a 140 grain bullet over 41.5 grains of H4350 loaded at 2.800 COAL is a "gold standard" so I tried that with 140 ELD-M bullets and it shot sub half MOA with good ES/SD (dont remember exactly what it was). When I ran out of 140 ELD-M and they became hard to find I bought a box of the 140 SMK and tried the same thing. Again sub half MOA with good ES/SD, just a bit lower BC than the ELD-M.

Good shoot BTW.

I don't even remember where i got it to be honest. No name on it.

You walked right into the load! I have never been that lucky!

Nope I'm 66 and my accuracy sucks.
