I got out for the second range trip today.
Put another 200 rnds down range,no isues.

I got a few sub MOA groups and a lot just over.

I discard any thing over MOA.

Here's a few pics of the Targets,if anybody is interested.
First target is TMK 69 g loaded over CFE 223,
As you can see, one group was Sub MOA.

The rest are all shot with 53 g Vmax and CFE223.
Not sure of the powder weight,as they were made a couple of years ago:)

I threw in a couple of 10 rnd groups as well.


And before anybody gets their panties in a bunch :)

The random handloads were developed for an XCR, using the exact same Hornady Vmax 53 g bullets, CFE and FL sized brass.
All 5 rnd groups, shot at 100 yards.IMG_0681.jpgIMG_0694.jpgIMG_0682.jpgIMG_0689.jpgIMG_0693.jpgIMG_0691.jpg

Just curious, how do you not know the powder charge? Don't you keep a log book of your loads or do you just pick a random charge between min and max and build 50 of them and expect sub moa because they're handloads? Not keeping good records would make it pretty hard to duplicate if you had tested them and you got 1/2 moa groups, but if you're just not the type to share powder charges I understand that as well.

That's some pretty good shooting but you aren't being very realistic expecting every group to be sub moa unless you're shooting off a sled and there is absolutely zero wind. There are too many variables that can throw a shot. This is one of the reasons I've started doing load development over the chronograph as well, if a 5 shot string has a very low ES and looks good on paper I'll retest that load and see if it can do the same repeatedly. If the muzzle velocity jumps all over the place but the target still looks good I figure it must have been a fluke group (but I'll test it again anyway since the target seldom lies). If the ES is very low but the target looks bad I'll retest that load as well to make sure it wasn't just me that pulled a couple.

I'd be pretty happy with those groups if the ammo is old handloads that weren't developed for this rifle.

This article is where I got the idea to incorporate the chronograph into my load development. I'm chasing a low ES and have no concern with the actual velocity until I find an accuracy node, then I look at the books to see if I have enough room to try to keep going faster to the next node or if I should be happy where I'm at and just refine that load.
This is the method I used with my MH and I quickly found a load that is hovering around 1 moa, I'm currently using Hornady SST projectiles since my first goal was to develop a good hunting load, I'll try some better projectiles this summer and try to see what the rifle is really capable of.
It's a three part series so be sure to read all three articles if you like what you're reading.
They also have a bunch of other good articles if you have some free time to bounce around their site.

I had an XCR-L,couple years back.
I developed a MOA group for it and loaded 1000 rnds for it .
But as things change, the MV was introduced and I sold the XCR. ( I've learned my lesson on doing that:))
Back then I was only interested in finding good loads.
So no logbook.
I could pull one,as they're all the same. 53 Vmax and CFE.


As for the new development,I'm just looking for the best groups.
Which I've found for both bullet types.
I'm going to load around those groups next.


I don't expect all groups to be sub MOA, but do expect the good ones to be consistent.
I'm not the best shooter, so I expect the occasional outer.

Then I'm going to do 5 ,5 rnd groups on the same target.

I'm now taking it a bit more serious and recording my data:)

I've searched for the range buddy app, but it's not there.

Are you apple or android? It's android but if you're an apple guy I would guess they have something similar.

I know exactly what you're saying about selling rifles after you find a good load. I've had four 223 NR barrels for my ACR, three HK SL8's and a few others (just in the 223 semi auto category) that I've found great loads for then had to start over.

Apple,they have Two, I guess I'll just pick one?

Ahhh, there's your problem :p

As an example here is what it looks like when you use the app, you can mark your pic, have it score the hits and, export the marked pic.
It's all manual entry. You set the scale, enter the bullet dia, mark the POA (the black X), mark the holes (adjust the screen zoom so the circle just covers the hole), then enter all the info in the white box and put it wherever you want on the target. It's really easy and takes all the guesswork out of it.

I'm waiting for a stripped receiver set.
I'll build my own,CFW ,chambered in 6.5 :)

But then you'll have the little Grendel not the wonder Creedmoor :p
Are you going to sell the MV and buy the MV-s set or keep this one and also buy those?
I think I need both, I'm planning to wait for the MV-s sets to be released and build a Grendel, 300BLK, and 223 upper for a single lower. I've already got a NR length 300BLK barrel to use :)
I'll have to look more closely at the Grendel muzzle velocities but I was quite surprised that the CM doesn't have higher MV's with so much case capacity behind it. It's not like it's slow but I was expecting a couple hundred more FPS.

I note that you are using your micrometer to measure outside to outside to obtain group size.

This will indicate larger groups that what you are actually achieving.

Measure center to center or outside to inside.

Yes, I prefer center to center but it's a lot harder to be accurate like that which is why I've switched over to using a phone app to do it for me.

yes I've been measuring outside to outside,then subtracting the bullet diameter.( .224)

I'll probably sell the MV and Votex gen 11(at a loss ) lol
I'm planning on a .223 and 6.5 Grendel uppers.

Both with CFW barrels.

Because of our wildlife regs, I'll be able to take both ,in the bush,almost all year.

What do you mean almost? Where do you live?
In Alberta I can carry any rifle I want any time of the year but I can't hunt big game with the 223. I can however still shoot coyotes with it 12 months a year.
I'm not sure if I'll keep my ACR after I build my MV-s rifle, performance and side by side comparisons will help me decide. Not much different than when I had my HK SL8-4 with Hera Arms lower, my Swiss Arms, ACR, and AR180B-2 all at the time. The ACR and AR180 remain and the rest were sold.

NL ,10 months for coyote and spring and fall bear hunt, for the 6.5 :)

June and July is total no go. It's for the berry pickers :)

Lol, you have some weird laws out there. Can the berry pickers carry a 12ga for bear defense? Or is that only on bear defense Thursdays? Or was it bear defense Wednesdays? I can never keep it straight which day it is :p
6.5G for bears? seems a little on the light side for my comfort level, I'd be carrying a 45-70 :d

We use the women for bear defence,they're tough as nails:)

6.5 should be capable,for anything on this island:)
