SWIFT SCIROCCO 100 YD TEST

I just shot a set of test loads using Varget, Winchester brass and primers and the 150 and 165 grain Swift Sciroccos. Using a highly accurized Rem. M-700 and a Nightforce 5.5-15 scope I managed sub 1/2 minute groups with each bullet. 42 grains of Varget shot 0.457" for five @ 100 yards with the 165's, 44 grains Varget/165's shot 0.470" and 43 grains Varget and the 150 Scirocco shot two groups that went into 0.440" - 0.454". O.L. was 2.81 for both bullets. I did not use my chronograph will do that another day. I did get pressure signs at 45 grains with each bullet.

Thought someone might find this interesting. I weighed 200 of the 150 grain Sciroccos and the extreme variation between the heaviest and the lightest was exactly 1.0 grain. This is the best consistency that I have had with Sciroccos since they came out.

Excellent results with this bullet that I consider to be a good compromise between the stoutest bullets and those with more rapid expansion like the BT's and Matchkings. It has a very good BC in its .284 counterpart.

Len,
Shot again today - have now got four sub 1/2 miute groups with the 165's and 44/Varget. Best group so far went 0.490" for five shots at 100 yds with four shots just under 0.3".

Needless to say this is going to be my caribou load in a couple of weeks. Will chronograph it and let you know how they are moving. O.L. is 2.81" for this rifle.

Re: SWIFT SCIROCCO 100 YD TEST

Ian--please tell us your results if you take a "bou". On a post a while back a guy used a 180 out of a 300 wby on a deer at very close range. He was shocked because he didn't get a pass through. It seems the bullet held together just great but because of the high impact speed it got a really huge mushroom and it was enough to stop it just under the hide on the other side. I would think it will be an excellent choice out of your gun for a bou!

Re: SWIFT SCIROCCO 100 YD TEST

I have been fortunate to do quite a lot of testing of the Scirocco (including a batch of wild hogs in the initial tests in Texas) and the bullet has consistently exceeded the objective of 70% weight retention, more like 80% as a matter of fact.

I hope to further the testing on caribou next week near an Eskimo community called Puvirnituk in northeastern Quebec.

That deer kill was shot with a .300 Weatherby at about 50 yds - amazing performance.

Another bullet that is very interesting is the new 168 grain Barnes match-grade hunting bullet - solid copper, nice high BC. We are getting good long range accuracy and hope to shoot something with it also.

Re: SWIFT SCIROCCO 100 YD TEST

For anyone interested here are the drops for the 165 gr. Scirocco pushed by 44 gr. Varget in Win. cases, Win. primer. Shot from a 22 inch barreled rifle, not sure of the velocity yet.

165 Grain Scirocco Load Ballistics

Distance Drop In Inches Drop MOA
100 yds 0 0
200 yds -3.75" 1.75 MOA
300 yds -15.0" 5.0 MOA
400 yds -35.0" 8.75 MOA
500 yds -58.0" 11.5 MOA
600 yds -91.5" 15.25 MOA
700 yds -133.0" 19.0 MOA

Accuracy remains excellent with sub MOA groups out to 700 yds, some 3-shot groups exceeded 0.5 MOA.

Re: SWIFT SCIROCCO 100 YD TEST

Ian,

Thanks for posting the data.

I have chosen the 165 Scirocco for my deer/hog/black bear bullet in my 30-06. This 30-06 was built by John Ricks, and is my "lightweight" rifle at just under 9 lbs with the mounted scope. It has a 26" Pac-Nor 3-groove barrel in #4 contour, a Lone Wolf stock (pillar bedded), and a Leupold 3.5x10x40 AO scope in Burris signature mounts on cross-slot style bases (I can't remember who made the bases--Leupold I think). The chamber is a touch on the tight side, but all brands of brass will chamber in it. The throat is cut parallel. I had John throat it for the 165 Scirocco, which is a fairly long bullet.

I should get it back from him next week. I hope the 165 Scirocco shoots in this gun--I have no reason to believe it won't.

Blaine
