I have a TC 45 ACP octagon barrel and was wondering if anybody else has any experince with one. I have been thinking of tring a 235 gr SWC (its an old lyman mould 452423) with around 6.5 gr of unique. According to Sierra with their 240 gr bullet Max load is 6.7. I am wondering if the barrel could produce a vel of around 1000 + fps.
