Three shot group..............

[Richard]

Today was a warm 65* cloudy/misty day that had a fairly strong tail wind howling from behind our range house. Shot several experimental loads with some new powder and at varying amounts. While the results were decent, they were not as good as last week. I had a duplex that I have been slowly downgrading the velocity. Initially it was 10/60.........N-110/N-120 in the 3,000 fps range. Last week I shot 10/55 and it dropped into the 2900's. This week I shot 10/50 and was into the mid 2800 range. A four shot group went .819" with the fifth one out? Any way, I decided to try it at 300 yards and switched to the 195 gr. Barnes which I had machined the bevel off. This bullet is now at 190 gr. As can be seen from the photo, three shots spanned 1.271". Why not five??? ;D..........Bill said: "you better save this three shot group for your forum " Since the wind was starting to get up a bit, I decided to leave it at three.

Richard, UN--------- BE----------LIEV---------ABLE ;D What a load and great shooting. Gotta be one for the record books. What do those 190 gr Barnes sell for? , Rusty

Very impressive Rich!
Especially with the wind factor.
Looks like you found a sweet spot at 2800 range.
Is that screamin? ;D

Well done, Richard.

Deadon, They are 195 gr barnes with the base machined off which makes them 190 gr.

very nice!

Really impressive Richard.... Really impressive!

[rexxer]

Only three shots Richard,hmmmm, I would of quit too! Next week I'm expecting five. Really nice shooting!

[Richard]

Thanks guys, appreciate the comments. Maybe I should just shoot three shot groups? It seems to generate more comments than when I shoot five?
I might mention that Herman blew one sabot today with the 17/56---N-110/N-130 duplex at 3000+ fps using the 200 gr. SST. I am in the process of making up some .400" veggie wads to insert into the sabot (like used to be done with the washers in the .50?) under these bullets with the bevel on the base. Hopefully this will fill the void and keep the bullet from pushing thru. I believe they need this support on the edges because thats where the most strength is. I am using a 10 mm shell casing to cut the center out of my .45 wads. This could be a fix for the SST's and the older Barnes.

Richard, impressive as usual. What are you using between the powder and sabot?

[edge]

I assume the first group @100 was with a SST or XTP with BH sabot.

Interesting that the groups look almost rotated 90 degrees!
Less than 1 caliber dispersion horizontally with the top group...and @300, and then less than 1 caliber vertically in the second!

It seems that the different bullets like the speed range but perhaps not this exact load. I think that I smell 1 grain adjustments for next week ;D

edge.

PS as an afterthought, did you chrono these loads and if so was there a marked difference between the two different bullets?

[deadeye]

excellent!//300yd groups reveal 3x the info.

[shooter]

Richard,three is plenty great shootin

Richard. very impressive and informative as usual.

Edge............Here are the chrono results for group #4 at 100 yds.
200 XTP
1. 2842 2. 2837 #. 2836. 4. 2850 5. 2830 Av.= 2839 ES = 19

300 yd. group:
1. 2844 2. 2854 3. 2853 Av. = 2844 ES = 28

When you look at the vertical dispersion on the 100 yd. group, it is entirely possible to get that group at 300. The distance in between shots 1 & 4 is about 1/2" which would translate to 1.5" at 300.
Here again, I did not really compare apples with apples. I should have had a larger test sample at 300 yards. Also, I should have shot the 100 yard group with the Barnes also I just find it more economical to shoot the XTP's for general load/accuracy development. In this case, I only loaded ten shot total and was curious about the Barnes at 300? It is more aerodynamically constructed than the XTP, even though I have the nose somewhat pointed up..................AND, it is nothing more than a "plain ole' " pistol bullet. We are really stretching what we expect from these MADE FOR SHORT RANGE bullets at the RPM and VELOCITY they are being shot at. If we could only get Sierra or Hornady or one of the other companies to produce a flat base Match King bullet. Then we might see some better groups. Right now, I believe you need a little luck to get really good groups consistently. You almost have to expect some flyers
SW..........no wads of any type under the sabot.
