Why are rem Scirocco bonded bullets so hard to get to group, is it a poorly designed bullet? Is this more often true with the factory loaded stuff, or to reloaders. Personally I don't reload, and after trying the bullets thought they shot fine, seems most people say "It's a great bullet if you can get it to fly" I guess I'm wondering if there is some sort of inconsistency with the bullet and I fluked out! Wondering what you guys who know your bullets have to say...thanks...

I shoot a Rem. 7mm RUM SS LS and the factory Rem. 140 Partitions were 3" groupers. I handloaded the 150gr Sciroccos at moderatly high speed and they shot 1" groups the first time out. It's not quite all luck but you know how complainers may be posting messages more often than satisfied shooters. Who knows. There's plenty of posters here who do like Sciroccos. I will buy all 7mm 150gr Sciroccos from anyone not happy with them.

I'm new to reloading rifle cartridges,but have asked many questions and the answers I've been told have been very helpful. But to answer your question I will give you an answer that has been given to me by many reloaders and bullet manufactures. To start factory ammunition is loaded to function in every type of firearm chambered for a specific caliber, So in otherwords different types of factory loadings work better or worse in different guns. So if you shoot factory ammo the smart thing to do is buy different brands and loadings and figure out which ammo works best for your gun. Asfar as reloaded ammunition the same rule aplies but you can adjust your loading to your rifle and make the ammunition work in your gun, for example you can adjust the powder charge and bullet seating depth untill you find whats called "the sweet spot" you will know when you hit it your ammuniton starts grouping very nicely, but it can take awhile and many loadings before you find it. So if your gun doesn't shoot factory loadings of the Rem Scirocco AKA swift Scirocco very well then the only alternative is get into reloading which creates the option of being able to adjust your cartridge to work best in your gun.

I am sure its a great constructed bullet. One problme is its thick soft copper jacket. You couldn't load a 180gr scirroco to the same load as a matchking. They build pressure fast. When I tried, I used very slow powder in my 300RUM like H1000, and RL25. Factory also shot 3" groups worst case. But I believe the faster powder would help. I bet a man shooting 180gr with IMR4350 might have luck. I am starting to see success not only with Scirrocos and RUM, but solid shank bullets and win mags, and rem mags and 30-06's by using less of the slow buners.

You might lose some velocity, but with any of the magnums, you have velocity to spare.
