Service Desk Posted September 23, 2019 Share Posted September 23, 2019 I am looking for some Bianchi loads for 115gn JHP and 125gn JHP - caliber is 38 Super, Open gun. Link to comment Share on other sites More sharing options...
Alan550 Posted September 23, 2019 Share Posted September 23, 2019 Most are running 4.6-4.7gr WST with those bullet weights. Keep the ammo out of the sun 'cause it's inversely sensitive to heat. Link to comment Share on other sites More sharing options...
Service Desk Posted September 23, 2019 Author Share Posted September 23, 2019 Thanks Alan550....I will load some up and see how they perform. Link to comment Share on other sites More sharing options...
Action Pistolero Posted September 24, 2019 Share Posted September 24, 2019 OAL with a Zero 115 is 1.220". This eliminates the temp sensitivity. Crimp is .477 to .478. Use NO MORE than 4.8 grains. I cannot stress this enough!! This load is right at the edge of the pressure curve. Link to comment Share on other sites More sharing options...
Service Desk Posted September 24, 2019 Author Share Posted September 24, 2019 Thanks Kevin...I loaded some 115gn HAPs at 1.220" and 4.5gns ...will give them a try tomorrow. Link to comment Share on other sites More sharing options...
gm iprod Posted September 27, 2019 Share Posted September 27, 2019 I have been doing some research on the new ADI powders APS350 and APS 450. APS 350 is essentially old AS30, which in essence is Hodgdon Clays, works OK with 125gr (3.7gr), not so with 115gr. Looks like APS450 is not an exact swap for AP50 (Intl Clays). Accuracy is OK, just not as good as I get with Titegroup, 231 or WST, at this stage. WST at 4.8gr is maxed out in my guns. I found it to be a little too fast burning for the way my gun works. Much prefer Titegroup, which is essentially WSL, for my guns. APS450 being a tad slower burning works Ok with 115gr at around 4.7gr (1150fps) with Zero's at 1.225" OAL. Good enough for practice if you are short of US made powders. Link to comment Share on other sites More sharing options...
Service Desk Posted September 28, 2019 Author Share Posted September 28, 2019 (edited) Winchester have stopped importation of powders for an indefinite period of time....so supplies of the favourites, WST and 231 are drying up fast in Australia. I have just broken into my WST stockpile and found that 4.6 grains with a 115gr HAP shoots pretty nicely and feels real soft compared to 231 or VV320. I still have AS30N, ClayDot, AP50N and AP70N for practice... Edited September 28, 2019 by Service Desk Spelling. Link to comment Share on other sites More sharing options...
pskys2 Posted September 29, 2019 Share Posted September 29, 2019 Be very careful with WST it is Inverse Temperature Sensitive, it loses velocity as the ambient temperatures rise. I noticed it in the 90's with 45 acp and just this year a buddy went sub-120 PF with it at the 2019 MW ICORE Regional using 38 special, he had chrono'd it at 50-60 degrees and it was in the upper 90's to 100 at the match. He went from 800+ f/s to barely 700 f/s. Which was similar to what I had found. It may be popular so just be aware of it. Link to comment Share on other sites More sharing options...
gm iprod Posted September 30, 2019 Share Posted September 30, 2019 (edited) Winchester Australia, (Olin Corp) will soon be just a warehouse for imported items. Bringing Powders in from USA is now murderously expensive. A 20Ft container packed tot he rafters has about 11Tonne of powder and costs about $35K US to get from Hodgdon to NZ. Probably same to get to AUS, so anyone there had better find a way of using ADI. Not sure about any other brands, but anything out of the EU is likely to be an easier bet for the short term.

stardust tommy Posted October 11, 2019 Share Posted October 11, 2019 maybe this is a solution https://www.smallcaliberpropellants.com/en/our-products this is the manufacturer of most ramshot powders (Belgium, Europe) Link to comment Share on other sites More sharing options...
gm iprod Posted October 12, 2019 Share Posted October 12, 2019 Had a guy just get binned at our Nationals using WST, chronoed 124 2 weeks ago, not running 118. He is not a happy camper. Saturday was generally much warmer than 2 weeks ago. Not even left in Sun, but there you go. Link to comment Share on other sites More sharing options...
Action Pistolero Posted October 12, 2019 Share Posted October 12, 2019 I noticed you stayed away from the 470 club this time. What was the bullet, OAL and crimp on the rounds? 124pf is a little too close for me. Link to comment Share on other sites More sharing options...
Service Desk Posted October 13, 2019 Author Share Posted October 13, 2019 4.6 gns of WST at 1.220" runs around 1120 fps with a 115 gr HAP in my gun and shoots OK...I might try some on a hot day for comparison. Link to comment Share on other sites More sharing options...
Action Pistolero Posted October 15, 2019 Share Posted October 15, 2019 My load runs the same. A hand loaded round always shoots lower than a gun fed round. I've found that the shorter OAL helps the temp sensitivity a considerable amount. Link to comment Share on other sites More sharing options...
