Home Forums Reloading Big Game Rifles 7mm STW loads with 150 Scirocco II?

Anyone shooting this combo?

Rifle is a Winchester 70 classic stainless with a 26 inch tube.

I have almost all popular powders on hand.

I have used H1000 and 7828SSC in my Mashburn with some limited load work with the 150 Swift. Pretty easy 3200-3250 load in my rifle. Wished I had better data for you, but I'd bet 7828, H1000, RL26, etc would all do great things.

Try H-1000.

I bought a Model 70 STW to build a 375 H&H on for a song since some one had put a muzzle brake on it. In a case of "shouldn't shoot the doner!" I threw some loads together with old Remington brass and 150 TTSX's. Sighted it in and then worked up three grains or so and the next three three shot groups were all under an inch without me trying very hard. Probably should have dropped everything and headed to the nearest casino!

Also, you might check over at long range hunting dot com...the 7STW is still pretty popular over there.

I had an original Sendero in STW that shot pretty good, then rebarreled it with a 28" Lilja.

Both guns shot Retumbo about the best, with the Lilja running 3425 with the 150 Sciroccos.

Ended up selling it for something else shiny......

Thanks gents.

I have an ample supply of RL25, H1000, 7828 and Retumbo.

If it helps I run Norma mrp under that bullet in my mashburn. Goes 3180 from a 24 inch barrel.

I have had my best luck in this caliber with Retumbo also regardless of bullet used.
