Re: 300 Holland & Holland ...anybody played with this one ?
I'm not a user, but that old boy will keep up. You stuff a 208 A-Max or any of the 210 bullets on top of some of the new powders (H1000, Retumbo, RL25), you are going to get some nice results.
I just looked at the reloading manual. Compared to the 300RUM you are going to be about 50-100fps below the RUM with a 200grn bullet according to the manual. The RUM has more volume and the same length. The H&H has the same length, but has a severe taper. SOOOOO... I think with modern powder (RL25 being the accuracy powder and best velocity) you should be fine. I know that you should be able to outperform the manuals with good hand loading and depending on your set up and barrel length. I didn't check what they used for test barrels for both rifles. This info is from the Lyman 49th edition.
