It is not the powder. It is the bullet. Most 1-12twist barrels will not shoot the polymer tip 40gr bullets worth a crap. You need a faster twist. If you want to shoot a 40gr bullet shoot a 40gr berger BTHP. They shoot great out of the 1-12 twist barrels!
Thats's right, it's not the weight but the length of the bullet. My remmy xr-100 .204 will shoot 32s, 40s and 45 grain bullets no problem but my kimber is picky and prefers the shorter length of the 32s and 45 gr. soft points.
