RS 62 vs RS60

[Doric]

I should have added - how much difference in barrel life would it be realistically? Has anyone tested it and come up with any real world results?

I used RS60 and burned out a Bergara barrel in no time. RS60 is a double base powder so let the buyer beware. RS62 is a lot more barrel friendly .

It’s ok, it’s been 4 years…I still use RS62 with good effect…

I’ve recently run up some loads with RS62 and still not quite at the velocities I was trying to hit (around 2850fps) for a 6.5CM with 24” barrel.

I’m loading 123gr fox copper, and 120gr and 140gr Sierra SP’s.

the 120’s and 140’s of can load up a little more as there is room however the fox 123gr I’m hearing some significant crunching and compressing the charge when seating. @malmick kindly ran the fox load through GRT and it’s showing I’m way up there in case fill as I’ll most likely need 43.5gr of RS62 to hit the 2850fps which is 100.1% case cap.

With the above in mind would I be better switching to RS60? Is RS60 the same as RS62 in that it’s between single and double base?? (I believe it’s like an I between in the case of RS62)

any input appreciated.

RS 60 has a slightly faster burn rate

Or, as far as I can tell, is actual fairy dust.

I appreciate that someone stalking for profit/professionally will be concerned about the cost of his tools, but how long does it take the average hobby stalker to shoot 1000 rounds, and is it really an issue for most ?
