[QUOTE="highdrum, post: 2872013, member: 13732"] I've owned 2x 22 creeds, one 8tw, other 7tw. The 8tw a 22", the 7tw an 18", load development has been very simple with both. 22cm with it's add case capacity offers a few more powder options, H1000 can be used with the 88+ gr bullets, 7.5tw stabilizes pretty much everything. It's important to get a 219 bore barrel VS a 218 in my opinion, as the 22cm is overbore and will develop fire cracking in first 400 rounds. Once this starts, slight jacket damage occurs as it goes down the barrel, and gets worse as throat condition deteriorates. A tighter bore combined with jacket damage, causes jacket failure in flight. 219 bore will help prolong the time before this becomes a problem. Also, buy you're brass first, load some rounds, check the loaded neck diameter. A lot of smiths have reamers with 257 necks. In my experience with my first barrel, this was too tight and I had to neck turn brass, using necked down lapua 6cm.
