I have a bunch of Woodleigh 215 gr 303 coming but all I have used is 470 softs and solids and they perform perfectly at the 2150 ft/sec they were designed for.
As previosly stated, Woodleigh is very clear about their bullet desigations and for what purpose they were designed for. They usually suggest heavy bullets for caliber. Their catelogue indicates recommended impact velocities as well.
For instance, the 215 303 is 1800-2200 ft/sec. The 174 gr 303 is 1800-2400 ft/sec.
I think you will be happy with the results of those bullets if you use them within their envelope of use.
