I recently built a AR 300 ACC with a 16 inch barrel and a pistol length Gas system. I have casted and shot the LEE 312-160 and RCBS 7.62mm-130-SPL. All water dropped WW powder coated and sized to .309. I have been gas checking them as well (more accurate). All have shot very well although I have not chrony'd them iam guessing they are in the 1900 FPS with 18gr of CFE Blk. I have used H110 and IMR 4227 as well (I don't remember the charge weights off the top of my head)
However I would like my son (9 yrs old) to use this rifle for a up coming hog hunt. He is a little recoil sensitive due to a Stepfather putting him behind "to Much gun to early" so I am looking for any load recommendations to start working with , and /or your experiences with cast 300 acc in hunting situations.
I have also played with the idea of a subsonic cast hunting load for this as well and I have a LEE 2-CAVITY BULLET MOLD * TL309-230-5R on the way it should be here Friday.
Any thoughts will be greatly appreciated (especially by a 9yr old who really wants to get a pig)
Thanks Guys
