    speer 90g tnt and ar comp load testing

    going to start testing this combo today and see how it does

    speers data calls for 28.8 as low end and 30.3 as max so this shouldnt take long to come up with something , knowing my rifle im going to start at like 29.2/4

    There's just no way that s 29.4g and my rifle hates compressed loads . I'll fill one more case n see what it does but looks like I'll be sticking with ppv

      Couple quick measurements I took show powder is in the neck but from top of the case down I have .200 of an inch so I loaded 3 rds at 2.235 oal this leaves base of the bullet .020 thou above the powder. Book calls for oal of 2.190 which is what I've always loaded to

              no drop tube , put i did put my finger over the case mouth and tapped it on the bench a few times sunk the powder a lil bit max lenght for mag is 2.265

              its just my goto varmint hunting bullet , i normally load these over 32.5g of ppv at 2.195 oal for extremely accurate results at a mv of 3050fps , just figured id try some with ARC since i have some
