First time Savage Build, questions and progress

[Rocketvapor]

Here's what happened last Thursday.
I loaded up a primer weight to muzzle velocity test for my AR with heavy CCI primers and light primers.
But, not going to talk about that here :)

Flo shot 10 rounds with CCI450 primers and 10 rounds with WIN41 primers.
Shortly after we started we got a Sensor message on the shotmarker and rounds drifted right about 3/4 to 1moa.
Velocities were about 50 to 100 fps less than expected in spite of muzzle velocities normal to a little higher.
Everyone I've talked to said one sensor shouldn't cause that.

Here's 10 shot groups from my AR on two different days, extreme heavy and light primers.
My intent was Velocity Vs Primer weight. Odd# was light primers one day and reversed to odd# shots were heavy primers on the second day.



So on to Flo's results, shot 4 foulers then a ten shot group.
Her group shifted RIGHT and ShotMarker velocities were also lower.
Even with that she got a pretty good group with CCI Primers (all about 3.66grains).

Her Garmin data for the ten shots were:
Flo 3/21/24 Savage 22N
CCI 450 3.66gr 31.8gr SB6.5 85.5
10 shots
min 3002.3
avg 3018.2
max 3033.1
ES 30.9
SD 11.2
3000fps at the muzzle usually gets about 2000fps @ 600.
Did I mention she REALLY likes the trigger @ 7oz :)
We go back this Thursday to practice some more.

Here's the progress on her firing pin (STILL HAVEN'T made it to town for the 1/4X28 set screw )

Info gathered mostly from old posts by Fred and Dave.

Pin protrusion is about 0.035-0.036", compared to new pin @ 0.058".
Drilled into the bottom of the cocking piece about 1.5 to 2 threads to shorten pin length about 0.045" (increase fall).

Used the Colt Commander flat wound spring Dave found. Force was a little low so I used 2 races from a Chinese 10mmX5mmX4mm thrust bearing, got 10 for about $8. Had to ream out the 5mm ID with a carbide spiral bit to fit over pin shaft. 11X5mmX4.5mm (5mm reamed to 6MM) would probably fit down at that end of the pin.
Could use one each 10mm and 11mm, or two 11mm for a small range in mass and spring force.

Used new BAS and a 10mm carbide micrometer tip and another 10X5mm race. One wrap of 0.002" Kapton tape trimmed to carbide tip. Tip ended up recessed about 0.030" after the addition of the 10X5mm race.

38cal case head bored for a 1/4" Ceramic ball, snapped in with vice adds about 0.127" to internal length or 0.097" including BAS recess (0.127" - 0.030"= 0.097).
Could eliminate race inside BAS for about 0.080" recess, 0.127"- 0.080" = 0.047" total inside increase.
No external shim.
Will continue to monitor performance but worked with 41 type primers.
This is NOT a Thrust Bearing "KIT". It is a Chinese thrust bearing (eBay), used for the races only.

Made a range trip to Saorsa Acres in Bogalusa.
600yds, windy as heck, then some 100yd shots.
Flo dialed back to her previous 100yd zero and shot at an 8" target ,push pin in center as a POA (bad idea ).
Shot the 4 sighters then 10 shots with CCI 450 primers, then changed target and shot 10 with WIN41.

Flo dialed back to her previous 100yd zero and shot at an 8" target

What power scope is she using ?? I would have her shoot at a much smaller
target center. Have her shoot at a white 1/2" dot. Adjust the scope over so all hits
stay off to the side of the aiming point. Are Yinz setting out any flags or wind streamers ??

Only brought 8 inch targets (for 600).
We usually use 1 inch dots on a white piece of typing paper.
This was just an ad-hock check of scope zero. She might need to come 1/8 MOA to the right.
This was a 40X Burris. Last 100yd zero was a couple hundred rounds ago, probably in Dec.
No flags around 100yds.
Flags down range were busy :)


Shot a couple different loads @ 600 (31.8gr, 31.7gr) then 31.65gr @ 100.

She really likes the trigger @ 7oz
5 second video.

We are in San Antonio, visiting daughter, grand daughter, and brand new Great Grand Son.
SAW the Texas Air Show, Cloudy Eclipse and will pop in for a quick visit with Lance and Naomi.
(After getting new tires put on the truck).

First trip to the range after our trip to Texas.
A 600yd match.
I shot a bunch of left overs and won't talk about my score
Took my time and loaded up 80 rounds for my little Savage and her 22 Nosler bolt gun :)
Sorted primers, Charged with SB6.5, 31.75gr (+/- 0.01gr), sorted bullets by weight.

She started off with a 196-8X, followed with a 196-6X. Not bad.
3rd relay I got her to pause and evaluate the group she had going after 2 sighters and 6 shots.

She adjusted UP 2 clicks (1/4 MOA) took a few more shots, adjusted UP 2 more clicks and shot her
BEST EVER 20 round group. 200-8

Total 592-22X, 98.7%
