[QUOTE="swampratt, post: 4222399, member: 15054"] Well the fat barrel rifle will get the barrel twisted in about .018"-.020" more. After shooting it a few times and measuring some cases the shoulder Ogive is getting pushed out that much after firing it. Cases are growing too long too fast. I built another and it is a skinny barrel .223 Axis again. It began life as a 22" long barrel and I cut it to 18" last night. I set it up to have slight drag with a full length resized case. Just a little extra pressure to close the bolt handle. Results for that little experiment was a case that was fired measures .001" longer at the Shoulder Ogive than a full length sized case. Brass should last longer. Resizing that low growth vs high growth case you can definitely tell. Kind of like AR vs bolt gun brass when resizing. We will see if accuracy suffers. [/QUOTE]
