[QUOTE="MontanaRifleman, post: 843342, member: 11717"] The short bearing surfaces of the hybrids apparently increase velocity/pressure ratios. Broz reported about a 50 fps gain in velocity with the 215's over the 210's in his 300 WM. In my RUM, I was getting 3130 with 93 gr of retumbo pushing 210's in a 26" tube. Using RL33 in a 27" nitrided tube, pushing the 230 hybrids which have a shorter bearing surface, I think there's a very good chance I'll exceed the 3130 I was getting with the 210's. [/QUOTE]
