Twinpot Posted February 22, 2019 Report Share Posted February 22, 2019 First and foremost hello to all. I shoot and reload 223 and 243. I use IMR 4350 to reload the 243 and have achieved fantastic results, shooting 1 ragged hole at 100yds using 34g 4350 - sierra 85g spitzer sp - Fiochi primer - COL 2.622 - 3070fps I am now down to my last few throws of powder and cannot seem to source a fresh tub anywhere. I am hoping I can call on those more experienced that could suggest an alternate powder. The 85g spitzer works very well for me, so I would like to keep using the same pill. I use Vit N133 for my pet loads with the 223 and have plenty of it, so I don’t need a powder to load both calibres i.e Vit N140. I believe that the IMR is a slow burning, single extruded powder ( I could be wrong) and would be pleased to learn of a similar powder without having to purchase lots of different brands to find one to suit. Many thanks in advance Link to comment Share on other sites More sharing options...
One on top of two Posted February 22, 2019 Report Share Posted February 22, 2019 reload Swiss RS52 will work superb in both calibres you want Link to comment Share on other sites More sharing options...
drum Posted February 22, 2019 Report Share Posted February 22, 2019 Ive had good success with lovex so70 which used to be known as aa4350 i believe,in 243,might be a little bulkier than imr 4350 though. Link to comment Share on other sites More sharing options...
No i deer Posted February 22, 2019 Report Share Posted February 22, 2019 IMR4350 is a match with RS62 On my burn rate chart Link to comment Share on other sites More sharing options...
One on top of two Posted February 22, 2019 Report Share Posted February 22, 2019 RS 62 in a 243 is NOT the best , I have tested the crap out of it , if you going to use Reload Swiss powders for the .243 then RS 52 is the way to go . you could use RS 60 but it will kill your barrel . Take a look at the chart for Swiss powders and your see RS52 or RS 60 http://www.propellants.co.uk/powder-chart.html Link to comment Share on other sites More sharing options...

I am also using SO70 being marketed here as "Shooter's World SW 4350" It is a little slower than IMR 4350 but my groups from the 6.5 Creedmoor have been outstanding. I buy it by the 8 pound keg.~Andrew Link to comment Share on other sites More sharing options...

Malxwal Posted February 23, 2019 Report Share Posted February 23, 2019 Viht N160 is a favourite round these parts, usually circa 42-43gr under an 87gr Vmax. Link to comment Share on other sites More sharing options...
