I have a Post-64 Model 70 Super Express push feed .375 H&H with a rear hole spacing at .860" on the bridge. I know .330" is normal for post-64 magnums. Any ideas to this? Did they ever come from the factory this way? What is the normal ejection port opening as well?

Serial #G197XXXX if that helps determine anything

Thanks
