| I don't see much about reloading for the LAR-8. Am I in the right part of the forum? |
| I have found some very accurate factory loads ( Hornady) but I was looking for a starting point with do's and dont's as I have not reloaded for this type of autoloader before. It's been a while since I've done any reloading and there is a lot of new powders out there. |

I like varget or 4064 with either powder starting at around 41 grains behind a sierra 168 grain boat tail hollowpoint. case length at 2.800 winchester large rifle primer and a light crimp lee full length factory crimp dies are nice.
either powder will give you enough case fill to prevent double charging , work up slow in .5 grain increments . 46 grains should be max but you will find the sweet spot long before you get to that point . check your fired brass every round for pressure signs like ejector swipes and flat or punctured primers . I would suggest you use a beam type scale and weigh every charge until you find an accurate load then you can go with a powder dispenser and weigh every 10th load to verify charge weight. . I cant stress enough start low with your charge at least 10% then work up . jeff |

FWIW, AR-Comp is spec'd from -20 to +140F with only about 15fps variation. That's a big plus if you live in an area where temperatures vary a lot from summer to winter like here in MN.Also, it works with primers other than the CCI 200s. They just gave me the best 100 yard group without changing the charge weight in a head to head primer comparison. GM210M were almost as tight, with WLR and Rem 9 1/2 close behind.
Good Luck with whatever you wind up going with. Hoot |
