...using:

43.4 grans RL-15
FC Brass trimmed to 2.008"
F210 Primer
175 smk seated to 2.810 (really 2.79" to 2.8135" OAL but same ogive setting on micrometer)

75 degrees F. Out of MY LAR-8 w/ 20" barrel, this load Matches 175 FGMM POI and is within 2 fps (actually hand load is 2 fps hotter; 10 round average each of FGMM and hand load). This is just my experience, not a recommendation, always start low and work up looking for pressure signs. I realize that I probably could have added this to any number of similar threads but I'm pumped to have jumped my first reloading hurdle. I finally understand what guys are saying when they say a good load development session puts them in a good mood all week.

I will add another clone load using LC brass once I get to it. Cheers,
Adam
 
Interested in hearing your LC load. I worked up thre versions of M118LR with Lake City Brass. One is with 44g of RE15 in regular LC brass and the other is 43.5g of Varget in LC Match brass and the last is 44.5 XBR8208 in regular LC brass. All shoot great but the RE15 load is the most accurate. I use CCI BR-2 primers, trim and seat to the same lengths as you. BTW I have a 20" BHW barrel on my Mega.
