The P-Series is built on the PROSTAFF line of scopes. The New P-223 will be a 3-9 BDC reticle. Built around the .223, 55gr. bullet and 3240 fps MV. There is also a fixed 3X in the P-223 Series as well.
We came out with the caliber Specific Turret's last year but really started getting them out in July. Some of the guy's I have chaated with who have them are very impressed. I still don't have a set but will soon. I just need to figure out which cal. 300 win or .257 wbymag.
You will be able to choose the ammo, mv ,BC of whatever cal. you decide on and then have that turret custom made to appropriate distances. One of the real nice thing's about them is that from order to delivery is usually 10 business day's, pretty fast.I think the price is in the $99 range too.
