Hmm...I've been in a Sirocco (usual spelling)...the hot desert wind that blows off the Sahara (pressure gradient wind)...
but anyhoo...I'v had several contact me saying they can't get accuracy from the Scirroco 2 bullets?!
They are supposed to be a superior design, and shooters were dismayed after paying premium prices for them ,not to get good accuracy?!
Anyone have either good or bad experience with them? It would be interesting to see what results are found. I've had nothing but bad reports. Comments, please.
Thanks,
Tom

Well, since you asked. I used to shoot the original Scirocco in the 180 grain guise our of my .300 Win Mag with the average of all the groups fired with that particular load being .886"

When the new improved version hit the shelves I was elated. I bought a box and went to work. I tried the old tried and true formula...shotgun pattern. I worked it through IMR 4831, IMR 7828, H1000 and even RL22. H1000 teased me for a while, but not consistent. The only thing consistent about those bullets was the shotgun pattern groups.

I thought my gun had gone haywire...until I tried the 180 grain Accubond over RL22. Didn't take long to prove nothing was wrong with the gun.

I went through four powders and a full box (100) of the Scirocco II's in a gun that has shot everything else I have ever put through it reasonably well. They were the exception.

Long story short. I have spent my last money on Scirocco II's.

And on the 8th day God made the Accubonds

300winnie: Thanks for reply. What rifle did you try them in? I've had friends email me about the non-performing Scirocco II bullets..its very dissapointing to spend good money on a ballyhooed product, then have it dissapoint, for sure!
Reminds me of one of my instructors who was teaching ship design course...and he pointed out that when you used the testing tank on models...for development, and get design results...once you scale up to make the full size deal..it doesn't necessarily follow through as it did in the testing tank. So, the hazy point being made...even though Swift designed what they may think an improvement as far as their bullet technology/engineering goes...it just may not work well in practice!
I, also had very good results with the Nosler Accubonds & like them a lot. Thanks again, for your valued input.
Aloha,
Tom

re. bullets...at one time I called an expert bullet maker (Mike Brady) of Northfork Bullets, (I use his bullets & they work great for me, any of them, in any caliber & rifle, nonpareil!)
Anyway...I was wondering about bullet types in my original Newton rifle's rifling, which is shallow,
2 groove (basically like oval bore rifling)..and Mike suggested to use the lightest jacket, softest core bullets...because with the shallow type rifling, you want the rifling to engrave the bullets best...and those type would be best. In fact, a fellow once wrote, he had the same problem with accuracy due to the shallow rifling & actually loaded .303 bullets (.311") in the .308 barrel (same case, just oversize .311" bullets) and got good accuracy in his .30 Newton. Whereas standard .308" bullets wouldn't give good accuracy...
Where is this learned discourse leading...?
Well, it may be the Scirocco II bullets are just too firm or hard core to engrave well in high powered magnums...whereupon accuracy suffers or isn;t there. A softer bullet may take the rifling better. This is all just guessing...as I haven't done any tests of my own, but a suspicion of what's gone wrong with them.
Best Regards,
Tom

"Shot gun pattern" sound very familiar!!

Me too, have tried out the 130grs SC 2's in my 6,5x55 Mauser with very bad results. I thought that I might use them on my reindeer-hunt this season ,but had to give it up.
Had to buy a box of Lapua Mega, they worked well.
I will try them in my 6,5-06 too, and see if the just need more speed?!

Hi Arild: Now that Marc Jamison is going to make new .256 Newton Brass, you can have your 6.5-06 converted to .256 Newton (I know, I know, they are almost the same)...except a .256 Newton is classy, whereas a 6.5-06 is just...a 6.5-06!
Your friend,
Tom

White Bison,

The rifle I tried the Scirocco II's in was my stock Browning Stainless Stalker topped with a Bushnell Elite 4200 2.5x10x50mm.

white bison:

I have loaded the 90 grsin Scirocco in .243Win, 150 grain scirocco in .308Win, and 180 grain scirocco in .300Win Mag. All shoot .7 or better at 100 yards. By far it and the Nosler Accubond are the best two bonded bullets on the market.

Longshot

Tom, something tells me that you are fond of the Newtons! Am I right?

Tom,
I tried the 130grainers in my .270 Win, over H 4831 and VV N 165, played with increments and jumps, best results were 2,5 to 3 MOA against the TSX with @ 0.60 MOA. If you do not shoot farther out than 125 yards, the bullet will be all right.
Nice day,
Jan.

I use the Remington factory ammo and have had good luck with them. Rifle is a 300RUM and groups are sub inch at 100 yards shooting off a bunched up blanket(need to pony up for a rest).

I shot an antelope with the set-up at 175 yards and definitly did the job. I know it was over kill but my Buddy said bring the scoped gun.

Anyone have good load ideas for the 300RUM?

I get .67 MOA with the Scirroco 2 out of my 270WSM. I am using R-19 with fed mag primers. As I recall I am around the mid 60's with the powder charge. Notes not in front of me.

Sooo, some good, some bad...kinda makes me think the bullet (Scirocco 2) are a bit fussy then.
For..."Earl", I use R19 in my 7mm WSM & it gives the best velocity with accuracy for me...but I don't use the Siroccos, but Noslers.
Best Regards,
Tom

Bill Hobert, CEO of Swift Bullet Company, told me the following:

Sciroccos have their own nitche, and may not shoot well the same way another makers bullet shoots in your gun. He recomended backing them off the rifling .035-.100. He also reccomended starting with considerably lighter loads than intended to shoot and work up as presure allows.

Bill explained the difference in the Scirocco I vs Scirocco IIs as being changes in the the metalurgy, discovered in the process of making the smaller caliber Sciroccos and now implemented in all Sciroccos.

I have talked to Bill at the Shot Shows over the years and on the phone a couple of times. He and I may not agree about everything but I know he is making a first class hunting bullet. What he says makes pretty good sence and I find the Scirocco to be the best hunting bullet on the market personally. It does what it is advertised to do. Shoot pretty good and stay together.

This advice is in line with factory ammo, which have tolerances in freerun and PW, not usual in handloads. These commercials sometimes shoot remarkably well however and for some reason I do not fully understand, don't need any finetuning as we like in handloads.
The only other factory who advices a gap of 0.030 to 0.070" is Barnes, to my knowledge.
Nice day,
J.

My son just shot a moose at 120 yards with a 150 gr. sirroco out of a 7mm. The bullet performed well. It did not hit any big bones but mushroomed perfectly. After it was clean it weighed 143gr.
