8mm Remington Magnum 200 AB Loads

[7mmhunter]

I am about to start working up loads for 200 AB. I know every rifle is different, but looking for recommendations for a powder and charge to start. Load development is not fun with this gun, so if I can save my shoulder a little punishment.

Thank you in advance.

 

[MrBruce]

I can't speak to the 8mm Rem Mag but my Savage 325 WSM really likes the Nosler 200 AB with 64.7 gr of RL-17 and CCI 250. 2910 fps, ES 7, SD 4 with a .457 3-shot group at 100 yds. No fluke, as this was repeated on two different trips to the range.

Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 65000 psi, or 448 MPa
or a maximum loading ratio or filling of 110 %
These calculations refer to your specified settings in QuickLOAD 'Cartridge Dimensions' window.
C A U T I O N : any load listed can result in a powder charge that falls below minimum suggested
loads or exceeds maximum suggested loads as presented in current handloading manuals. Understand
that all of the listed powders can be unsuitable for the given combination of cartridge, bullet
and gun. Actual load order can vary, depending upon lot-to-lot powder and component variations.

I would give a look into Nosler's manual. See what they list as the most accurate powder, COAL, primer and start from there. Seems like 7828 and RL22 are really good in the big 8. Good luck with your bench work. Very cool cartridge.

Thanks for the replies. I am going to start with 7828. My 7mm mag like 7828 so will start there.

Prior to re barreling my 8mm to a 338 Jarrett I had very good luck with 81.5 gr. H4831;
