I have some problems with my Remington 700 Police in 300 RUM caliber. Could someone suggest what would be the optimum load ..... what primers, brass length,bullet, C.O.L. and powder ....

I tried with Vihtavuori n560 (84gr), Lapua bullets 185 gr Scenar silver jacket and CCI magnum primers. Unfortunately I didnt get good result, so now Im in troubles a little bit.

Thanks for any suggestion.
 
Go big or go home: 210gr Bergers, 210gr Sierra or 208gr A-Max.

VV N560 and N570 should be in the correct range.

Police were next to me one day at the range with 300 RUM 700P with a brake. Load development in magnums will be rough without one. They were using 208gr A-Max with R25. They bragged about 1/10gr increment load development, then I saw their groups (fist-sized).

For magnums, I make 5 rounds from min to max in 1gr increments. When I find the best group, I'll go back to .3gr-.5gr increments around that load. From there I play with COL and primers. 215M and CCI 250 have been better performers than WLRM. I have some Rem 9.5M loaded up to compare, but haven't shot them.

I neck-size my magnum loads.
