Does anybody have any full power data for the 260grain partition HG bullets with H110 and WSR primers? Also can you list the velocity of the loads.

Thanks

The 5th Edition of the Nosler manual lists the top loads for this bullet as 1942 fps for 32.0 grs of H110 and 1983 fps for 33.5 grs of W296. This is for a 12 inch Encore test bbl, so subtract 200 fps for a normal cylinder gap and a 7.5 inch bbl. Drop the charges 6% and work up from there with WSR primers.

Be Aware not all 452 dia bullets are designed to handle the max velocity that can be obtained with the 454. As I understand it some of the bullet manufactures do not use a thick enought jacket. When I started handloading for my FA454 10 years ago the only bullets recomended by Freedom Arms for the velocitys listed in their data were FA260 and 300g, Barnes 300g and Hornaday 300g XTP. this was for the very top velocitys which per the FA data sheets for FA revolvers exceed 2000fps for the 260g and 1780 for the 300g. I would image that with something like a closed breech contender the velocitys would be even higher. whereas with a shorter barrel ruger larger cylinder gap etc, the velocitys should go down. Now days with many more gun manufactures chambering for the 454 maybe the bullet manufactures have followed suit and beefed up their bullets. I have gone to nothing but heavy cast bullets thus haven't followed whats being offered in the way of expanding jacketed bullets.

Hard cast lead bullets are the only way to go because:
1. With the same charge weight as for their Jacketed equivalent, your MV will increase 150+ fps.
2. Often you can go 1-2 grains (H110) higher than the equiv Jacketed charge weight before you hit MAX.
3. The smart ones will back off the charge weight to match the jacketed bullet MV. RECOIL DECREASES measurably!
4. Expansion is not necessary from a .45 bullet to anchor the game. Most of the cast bullets will penetrate thru it. You can adjust penetration by the design of the bullet, its weight, its MV.
5. But an obvious advantage to what some inexperienced hunters call "overpenetration" is that if a deer is hiding behind a tree, you can shoot thru the tree trunk to make that 1 shot kill on the deer...as long as the tree is less than 12.7" in diamenter.

Cheers
