Looking for a little help with loading for my new Grendel. I have questions. My rifle was built in my shop. Has 200 rounds thru it as of today. Specs-20 BA DMR SS barrel rifle length gas, toolcraft BCG, superlative arms adjustable gas block, aero lower, CMC trigger, standard carbine buffer. I just started reloading for it but have some experience with loading 223. I would love to take this rifle to 1000 yards some day. Will the 123g SMK get me there or or should I go 129-130g? It seems to like 27.6g AR Comp @ 2.260 with 123g SMK. Also I tested today 129g ABLR with 26.6/26.8/27.1g of AR Comp @ 2.260. Shot .880 at 100 yards with 27.1. That was my best group today. I had slight ejector swipes. It really is different reloading this cartridge with me only have 223 experience. I just cant tell if Im to hot with these. Primers dont really look terrible but I really dont want to end up breaking my bolt or worse. Can anyone suggest a bullet? And maybe give me some advice on reading these pressure signs better? Thank you all in advance. Also I live in NC and would love to meet up with an experienced reloader I can talk with. I dont know anyone else that reloads.
