Guys i bought some 300 grain speer sp and 300 gr hornady hp-xtp bullets. My manual calls for 21.5-23.5 gr H110 with CCI magnum primers.

All I have on me are Winchester Large pistom primers (that are marked for standard and magnum.) Will it be ok to use the WLP with this data?

Also the Hornady data calls for 17.9-21.7 grains of Win296. I have heard that 296 and H110 are basically the same powder.

Will I be ok using the Win296 data for the H110 with the xtp?

One last thing. Does anyone have experience with these loads? I will be shooting them out of a New model Blackhawk 4 5/8 barrel.

Thanks

The WLP works with both powders. H110 data is on the Hodgdon website, different bullet. http://data.hodgdon.com/main_menu.asp

W296 and H110 are exactly the same powders and that has been verified by Hodgdon. Look at the Hodgdon Load Data Site (http://data.hodgdon.com/cartridge_load.asp) and you will see the same exact data for both. (where both are listed)

You can easily substitute a Win LPP for a CCI LPM primer. Unlike components in shotshell load data, components for handgun data aren't as critical. The Winchester Large Pistol primers will work just fine.

The Hodgdon data is different than both you posted but similar. I would start on the lower end and work up but don't go too low because W296/H110 doesn't react well to being downloaded more than 3% below the Max charge. The Hodgdon charge range is 21.8gr to 22.2gr. (always verify data you see on the Internet for yourself, never trust anyone because mistakes can and will happen)
