Canuck63 Posted December 20, 2011 Share Posted December 20, 2011 Hi all, I've got a hundred million bucks question for you!I'm running outta 200grs LSWC and next weekend I'm going to get 10k of them from my supplier.My 1911s (a Les Baer Premier II Super Tac,a Les Baer Concept V and an ADC Custom with a KKM bull) deliver ridicolously tight groups with .451 bullets but I could just as easily have them in .452...would I get more accuracy (just for the sake of it and out of curiosity )with them or I may as well save my friend the hassle of going and get them in the warehouse? My fave load is a slight variation of the "Wilson Load" that will give me a 175 PF,i.e. a .451 200 grainer over 4,7grs of N310,CCI LP primers and a 1.245 COL.My guns' barrel are virtually new,hence no wear to speak of.

robertbank Posted December 20, 2011 Share Posted December 20, 2011 Lead boolits should be sized .452 for the .45acp cartridge. You want the boolit to be at least 1 thousandths over bore size to ensure a gas seal to prevent gas cutting and the resulting leading.

buckaroo45 Posted December 20, 2011 Share Posted December 20, 2011 If you get "ridiculous tight" groups in all 3 guns w/ .451 why would you even consider .452? Maybe the question is what do you consider a tight group? Link to comment Share on other sites More sharing options...
FLSlim Posted December 20, 2011 Share Posted December 20, 2011 For lead, usually .452, but slug your barrel to check its diameter. Link to comment Share on other sites More sharing options...
Canuck63 Posted December 21, 2011 Author Share Posted December 21, 2011 (edited) If you get "ridiculous tight" groups in all 3 guns w/ .451 why would you even consider .452? Maybe the question is what do you consider a tight group? Hi Buckaroo, your reply makes a lot of sense!I consider the average size of several groups shot aiming at a 4"x4" white square at 20yds from a rest(not a Ranson though!)....I can get 1/2" (1" being the widest) single ragged holes in the middle of the square and add to that that I'm a real bad shot!IMO plenty of accuracy for IPSC matches but you never have too much, have you?

Canuck63 Posted December 21, 2011 Author Share Posted December 21, 2011 I should add to that that I also used .452 slugs with no evident increase or decrease of accuracy.I had thought to get a few .450 bullets to see if I can decrease felt recoil with them,but,then again,I could easily run into unsufficient sealing and leading!

whistlepig Posted December 21, 2011 Share Posted December 21, 2011 If your load shoots like that and you don't see evidence of problems, this question has answered itself....... Link to comment Share on other sites More sharing options...
