[QUOTE="BoatTail, post: 1257057, member: 74670"] I recommend you[B] not[/B] go with H1000. You will not get the velocities you will with Retumbo or RL33 and to do so will put your loads at too high a pressure. I built my first 28 Nosler shortly have Fred did his, before any published data was available. Nosler's Reloading Guide #8 now show the following max loads and velocities: H1000 79grs 3103 Retumbo 82grs 3166 RL33 88grs 3211 Using QuickLoad (a newly acquired tool) the max load is: H1000 80.5grs 3031 Before knowing this I did extensive testing in my first 28 Nosler with 175 gr ABLR's and obtained the data in the file below with a 25.5" Hart #3 barrel with a 1 in 9 twist: [B]NOTE[/B]: Everything past 79grs in this data is over pressure and should not be used. Standard reloading practices say that with a magnum cartridge, you have reach your maximum load when you have reached a case increase (measured where the belt would be with the 28 Nosler) of 0.0006 to 0.0007". I did not know that at the time and since I did not have a sticky bolt (new chamber) or see significantly flattened primers I kept going past 79 grains. I did see plunger marks and extractor marks starting at 80grs to the last but discounted that because I heard Nosler brass was soft. While I did see the best group with 83gs of H1000 it was way over pressure. Both Retumbo and RL33 provide better velocities with lower pressures and for me showed similar accuracy. I will share my Retumbo and RL33 load data tomorrow. Bruce [/QUOTE]
