sb7979 Posted January 20, 2003 Share Posted January 20, 2003 Just wondering what others are using for powder in a compensated 45? I have a Nowlin 3 port comp on a Springfield Hi Cap model and am trying to figure out the best loads to make it as effective as possible. I tried some 152 grain SWCs today with 8.0 grains of Power Pistol and they chronographed around 1100fps, which would make major, but they were light enough that they didn't cycle the gun reliably. Does this seem right? Does anyone have any recommendations for powder, or loads for a comped 45? Thanks Scott Link to comment Share on other sites More sharing options...
reddot Posted January 20, 2003 Share Posted January 20, 2003 SB79, I shot a bunch of stuff with an old .45 with a single port Clark comp. I always liked to pick the slowest stuff that would fill the case 80% or better and still burn clean. The last combination I used was 8.8 gr N340 with a 155 swc. That was for the "old major" maybe 7.5 to 8.0 would make new major. I used a12 or 13 lb spring with that. If you can't get it to cycle, you might try a lighter recoil spring. Let me know if you have any questions that I might help with. RD Link to comment Share on other sites More sharing options...
DougCarden Posted January 20, 2003 Share Posted January 20, 2003 Use a slower powder with the lead bullets, try unique. It works, but there might be a better powder. Remember to use a healthy crimp on the 152s. Doug Link to comment Share on other sites More sharing options...
TBF Posted January 20, 2003 Share Posted January 20, 2003 No experience with comps but hodgdons longshot has plenty of gas left over at the muzzle, it is relatively clean at max loads, never tried it for pf loads. Its listed as between aa#5 and aa#7 in burn rate. I am in the process of working on pf170 loads currently, but have not tested longshot yet. It works excellently in MAX loads for pins w/200 & 230 plated bullets. Travis F. Link to comment Share on other sites More sharing options...
sb7979 Posted January 20, 2003 Author Share Posted January 20, 2003 Thanks for the info guys. And just for the record, Power Pistol is slower burning that Unique. Scott Link to comment Share on other sites More sharing options...
IPSC CHIK1 Posted January 21, 2003 Share Posted January 21, 2003 back in the mists of time before the earth cooled, when i ran a comped 45 i used AA5, sorry, forgot the load, with 155swc. with your current load i suggest a lighter recoil spring Link to comment Share on other sites More sharing options...
Carlos Posted January 21, 2003 Share Posted January 21, 2003 Reddot and IPSChic are on the money; in an old Caspian single stack w/ comp. I tried N340 loads and it "worked" to the extent a comp will work on a .45. You could also try N350 or even N105 to get the comp working - and light bullets are the ticket. You can find an ad for lightweight Zinc bullets in the back of Shotgun News or try the Westcost 155 grn non-lead sintered plated bullets if the National Bullet 155SWCs are not to your liking.
