Hi Guys...I own a non ported Marlin 1895M .450 Rifle. It's a shooter with factory ammo & re-loads using the Hornady 350 gr FP bullet and IMR 4198 powder. I just purchased some Laser Cast 405 gr FP bullets, .459 diameter. I'm looking for some load data on these bullets using IMR 4198 and / or H4198 powder. I have contacted Laser Cast for .450 Data and they directed me to another site as they have none for the .450 Marlin. I tried www.reloadersnest.com and found some Data for the 400 gr Barnes FN bullet. I'm not comfortable using this data and would prefer information for the actual bullet. Any help from you guys would be appreciated. I'm new to this Forum and look forward to it. Thanks...... <img src="/ubbthreads/images/graemlins/wink.gif" alt="" />
