[QUOTE="MontanaRifleman, post: 859127, member: 11717"] There is a member getting close to 3250 in a 32" non-nitrided barrel with RL33 and the 230's. RL33 is the big kicker here. It's a very slow powder and my 27" barrel may not take advantage of it as well as a 32" barrel. Time will tell as soon as I get it back together from nitriding. 33 is going to be too slow for the 177's, so that is why the discrepancy in my "predicted" velocities. At slower velocities, the Berger will retain more of its mass. How much I don't know. But I do know it will arrive at the target with close to 30% more mass than the 177's. As far as bullet integrity goes, the GS bullet will have an advantage in momentum but the mass shed by the Berger will also do some damage. [/QUOTE]
