Nitro;

Did you use Hastings rifled shotgun barrels?

Are 12 bore or 20 bore rifled shotgun tube blanks available in USA now?

Best Regards;

Sorry for delay in replying been a little busy.
Yes these were Hastings barrel blanks.
E R Shaw and a few other companies have been making rifled shotgun barrels in the USA for a while.

See link above.

I am going out to the smith this weekend for final adjustment and shooting.

Damn impressive results.

Updated 11/17/11

More shooting pictures and a target added.
Still need to do accuracy testing.

Update 11/26/11

Well weather was 60 Deg. WOW.
I went to the range with the DR.
Shot 6 rounds at 25Yds from bench in led sled.
Lightfield 20ga 3" Magnum 7/8 oz Hybrid Exp.

25 yds.


50 yds.



Both targets overlaid.



Shot 100 yds also 3" x 1.5" 4 shot group.
Wind was blowing holes were not clean.
Maybe not stabilizing.

Update 12/03/11

Bill73 and I went to the range on Saturday.
Temp was low 40's and snow on the ground, 90% humidity.

Shot from the bench at 50 yds. and 100.
Elbows on the bench forearm hand suppoted by a sandbag.
6 shots at 50yds and 4 at 100.
50 yd was no better or worse than before.
2 1/2" by 1 3/4" group.

First 2 had verticle spread but no Horizontal.
Next 4 had little verticle but made up the 2 1/2" group size.
2 R were R and 2 L were L
I will attach the target later.

I shot a left over target at 25 yds.
Offhand and relatively quick shots.
This would be exactly as ahot in the field.
See target below.


Bill73 feel free to chime in your thoughts.

Cheers Nitro

Edit: This is the 50 yd target.



Looks like I need to try some more ammo types.



This is the 100yd target first 2 shots, I felt good about them, pulled the next 2.
Second shots had less verticle but lots of horizontal, off frame of the pic.
But I knew i pulled them bad.

Hello,

Here is a pic of the RMC brass stoked with Trailboss and SWC Slug (450 Grain) and RB (350 Grain)



The RB shot really well, super accurate, maybe 1.5 x 1.5 " group. 6 shots at 50 yds.
The leading needs to be worked on.
The velocity was 1540 R barrel and 1484 Left IIRC.
32 grains Trailboss.
I tore the target removing it almost one ragged hole at 50 yds.
Since I am not done, and will size the balls to reduce leading, I will have another update on this.

The slugs had really bad leading and very wide group, pressure was high.
Flat primer, and one primer leaked a little.

I also tried more factory ammo.
This is the Brenneke silver slug 20ga 3".
All targets 50 yds.



This was Federal Premium with Barnes Xpander.



This was Federal Fusion Sabot.



So far it shoots Lighfields, Brenneke and Buckhammers really well.
And ofcourse the round ball the best.

Well, I got some time to persue my 20 Bore DR loading.

I loaded some 350 gr balls over Blue Dot with 20S1 wads and 1/8� nitro cards in Multi-hulls (8)

Also did some Hammerheads over Blue Dot (just 2)

Did some of the BPI DGS slugs over 800X (8)

I did some more of the 350 gr RB over Trailboss, in RMC Brass, added lube in the case neck. (8)

Did some RB on a wad column over Blue Dot, RMC brass lots of lube in the neck (2)

The idea is shoot 2 over the chrony, out of the H&R SB1, check for issues if OK

Shoot 3 Rights and 3 Lefts out of the DR for accuracy and regulation.

The afternoons labour.



The wad column combinations.



Will post targets after shooting.
