I've been working a slow project to develop a CA compliant deer load for my 308. With FC brass and 46 gr IMR 3031 (near max-no pressure signs in my gun - work up in yours) under a 130 gr ttsx, I'm getting 3060 fps out of 22" barrel. JBM calc says >2K FPS and >1.2K ftlbs at 400 yards. That's not shabby imo and should work fine if i do my part. I'll let you know this fall. Good luck.Very much new to shooting a .308 , this season I had to shoot whatever I could find , Norma 150 white tail and I want to get some better preformance and was researching monolithic
seems like I need to drop some weight to 130gr ttsx , I look and 99% of the monos require
+/- 2000fps to open them. the .308 seems very anemic past 300 meters , thus has me worried about energy transfer with 150-165 mono’s .
question is should I just stick to CC like partitions & accubond in .308 or do the barns & sako
preform @ those low FPS <300 meters ?
