I've contacted Swift numerous times regarding load data for their 150g polymer tip boat tail Spitzer - specific to 7mm-08 Remington. For whatever reason they're not responding aftera few weeks wait. I frequently use IMR4064, Varget, RL-15, and RL-17. Can anyone please provide advice on this? Just can't justify buying their manual only to find my rifle doesn't like the bullets. This is the first and only Swift bullets I have purchased. Thank you.

I shot those Swifts in my 7 mag, same load as 150g Nosler ballistic tips.
Thank you. My question would be - the Nosler chart shows a fair number of 98-100% filling of the case capacity. That said, given Nosler Accubonds are 0.077" shorter than the Scirocco II's did you see any pressure issues? I'm already compressing with Noslers.
I load Rx15 with 140 grain accubonds with good results..light load of 41.5grs...I also load up to 47 grains of IMR4350 with good results...I would start around 39.5 of the Rx15 and work up....
Kinda late to this post but I have the Swift loading manual. Here is their load data for the 150 grain Scirocco in the 7mm-08 with a 24 inch barrel:
H414 41.4-44.5 grains 2726 fps
H-4350 43.7-47.0 grains 2764 fps
Varget 37.2-40.0 grains 2670 fps
RL15 37.2-40.0 grains 2695 fps (not a typo same charge weight as Varget)
RL19 44.2-47.5 grains 2680 fps
IMR 4064 37.2-40.0 grains 2698 fps
IMR 4350 42.8-46.0 grains 2728 fps
IMR 4895 36.7-39.5 grains 2696 fps
H414 41.4-44.5 grains 2726 fps
H-4350 43.7-47.0 grains 2764 fps
Varget 37.2-40.0 grains 2670 fps
RL15 37.2-40.0 grains 2695 fps (not a typo same charge weight as Varget)
RL19 44.2-47.5 grains 2680 fps
IMR 4064 37.2-40.0 grains 2698 fps

IMR 4895 36.7-39.5 grains 2696 fps

I would run R#17 first, H4350 second
Any suggestions or experience for starting and max grains - R17? Have tried H4350 already - decent groupings but man they're compressed.

Did you try using a long drop tube with the H4350? If I am getting good speed with accuracy on a short range hunting rifle, I don't care about the compression.
I shot a lot of Win 760 with the 140g, accurate and fast.

Another member on this site suggested to me a load that really worked well with a 154g Hornady, 44g of R#16 in Lake City brass, Rem 700 24" sporter...deer and hog load, not target load.
If you are getting good accuracy with the H4350, why not just run with it?

Agreed, I intend on running with it (H4350). But with current powder availability (or lack thereof) I'd like to have a backup load with another powder, hence R17 load data need. No, haven't tried a drop tube- but bet on it that I will. Thanks again!

10" Drop tube. Dabble the powder out of the powder pan into the top edge of the powder funnel, it will swirl on it's way down compacting tighter.
Since you have the H4350, Stick with it.
