Hello Ripp,

not exactly what you asked, but I shoot a conversion-barrel set in 10mm Auto for a LAR Grizzly.

I use 200grs Hornady FP-FMJ, Remington 180grs SPFN and Winchester 180grs HP with Kemira N110 or Blue Dot with reliable function and (for my skill) good precision.
In the beginning the pistol had some feeding problems until I reduced the OAL from 32,0mm/1.260"
to 31,7mm/ 1.248".

Another recommended powder in the 10mm Auto is the Accurate Arms AA No. 7.

best regards
Rolf
