AZ PewPewPew Meet aka @Mike330R shooting diary

12” Grendel barrel dimpling finished. Should get upper and hand guard today

 

dang it - i need to get out and dial in my 300blk - i have next week off, maybe if the weather cooperates.............

its also my daughters birthday week - but i should be able to get out and back before she gets out of bed.

 

Got it together. Wanted to direct thread the can but both Omegas have stuck parts. One has a 556 end cap stuck and the other has the ASR quick release mount stuck. Doh!

This will do for now.

 

Was able to do some load development with the Larue 6.5 Grendel.
Can't say I shot very well. The very top target was factory Hornady AG ammo which I have shot much better in the past.

I used IMR 8208 from 27.5gr to 28.4gr using both Hornady 123 ELDMs and Sierra 123 HPBT's.
The higher loads do show more pronounced ejector swipes.
I loaded 6 of each load and shot 2, 3 round groups with each.
Over all it appears the sierra's did better but it's hard to say if I wasn't doing my part perfectly.

I'm open to any thoughts or suggestions.

Pic's:

 

Looks like both like to be around 2500 fps but the vertical is not good. What primers you using?

 

Winchester.
Hard to say the vertical groups weren't me.

Plus the ejector marks on the 2500 fps rounds were more noticeable, should I be concerned?

 

If you have some CCI BR or Remington primers try them. They have a little thicker cup and are usually better with AR based guns.
Yes, the ejector marks are not ideal and I would not go any higher of a charge.

 

Thanks.
How would thicker cups help?

 

I just like them with the AR based guns, less chance of a slam fire and they seem to better handle higher pressure.

 

Hudson Mfg is going out of business so their H9 pistols are actually reasonably priced now...

 

I’m cheap, use a harbor freight moving blanket / pad

 

WTB: a cheapish .300 win mag bolt gun

 

Ha, was thinking a Ruger American or a 783 in the walnut stock

 

You should probably mention the trigger and bolt close

 

Just loaded up more grendel rounds all the same grains of powder.
Will compare Hornady and Sierra bullets again this weekend.

 

Does she shoot as good as she looks?

 

Will bring a drool rag
I'm headed out to one of my spots this weekend, need some long range play. Damn job takes up to much time.

 

Glad you are doing better! If you need to get out and shoot or grab a beer let me know.

 

Wow crazy. Glad your head didn't explode

 

Amen!
Been working with the Grendel's.
Figured out the load for the 18" and tried to sight in the 12" last weekend. Targets at 500 were blurry

Took the scope out of the mount and it appears the rings crushed the scope.
Was torqued to Larue spec's of 30 inch pounds which I have used with all Larue mounts.
Friend said his vortex scope called for 18 inch pounds.
Sent in the scope and hoping they replace it. It's a Vortex Diamondback 1-8. Damn cheap scopes!

Prob headed back out this weekend with the 18" Grendel and a few revolvers.
