The waiting game begin

These all remind me of the medical device assembly machines that I used to design. I guess that when I retired the functional part of my brain did too. That is why I want blued metal and wood. Forty five years of designing functional is enough.
 
I'm worried that the 56" objective of the Nightforce would be too big for Gruning mounting system so I borrowed my buddy Franks brand new scope and mounted it in my rifle. The scope fits perfectly and it looks good on rifle. So I called my buddy Frank to inform him that the scope got stuck on the rifle and it's not coming out.

No doubt, Frank accepted your representation. :lol: It does look good, however.

Components will be arriving next Thursday and I'm going to start load development immediately. I might just hijack the scope from Frank and buy him replacement when his rifle arrive. :wink:
 
Went to the range late this afternoon. I had one hour of day light left to shoot so no time to even set up the chrono. I loaded the 130 grain Berger VLD using IMR 4350 and Remington 7-1/2 Small Match primer. I can't find H4350 locally so I had to choose between Reloader 15 and the IMR 4350. I have both powder in my inventory. I choose the 4350 because it's a much slower powder than the 15.

I loaded 25 round, 5 each starting at 37, 37.5, 38, 38.5 and 39 grain. I seated the bullet .05" off the land. I wasted all 5 of the cartridge loaded with 37 just zeroing the rifle. I made a mistake on slapping the IOR from my 308 into the 6.5 without collimating the scope first. I should have known better. I already wasted 3 rounds when I realized that the scope was way -off.

I can see slight extractor marks on the fired case although barely noticeable. Extraction was fine however. I was ready to packed it in but out of curiosity, I decided to try the load with 37.5 grain powder of powder.

It's really getting dark and I could barely see the small red dot on the 6" Shoot and See target at 110 yards. I fired the first shot and I immediately noticed that the bullet landed about an inch low right at the target. I proceeded and fired two more shot but I can't see no other hole. I went to retrieved the target and saw that all three 130 grain Berger made one small ragged hole.

Here's the picture of the 3 shot group at 110 yards.

I will have to reduced this load by about a grain and start from there. I will also sort the brass by weight . This rifle is no fun.

That's like cheating. First group!! Quick send it back can't be that easy!

Nv, that what it feels like with Gruning Rifle :) You can load it with just about anything and it will plain shoot. I'm not surprised at the rifle accuracy at all. My Gruning 308 will do the same.

Here's the 3 shot at 110 yards with my 308.

My buddy Frank 300 Weatherby built by Gruning can do this all day long with Barnes 180 grain TTSX.

I need to find a stable load and stretched her leg a bit, and see how she perform at long distance. I only fired a total of 8 rounds. The brass showed slight extractor mark signifying pressure but my measurement of the fired case (web, case head and overall length) tells otherwise...still identical to the measurement of the unfired case, except the shoulder which have grown to .005" which is nothing. The weight of Lapua brass is very consistent too, ranging from 162.2 to 162.8 grain, none above or below the 162 grain mark. I have never seen brass this consistent. I attributed that to the quality of Lapua brass.

Thanks for all the comments gentlemen. :wink:

I dunno DF... Where'd the other two bullets go? :grin:

Congrats - things are looking good. Real good.
