Using SPP brass...

[ArrDave]

I have a lost brass match coming up and I have about 100 of these suckers ready to go. The consensus I seem to have read is that you us a Small Magnum Pistol Primer and go on about life. Do you goose your charge at all, or just let it ride? What's your experience?

I have just used a SPP and went about my way. I don't shoot matches though and don't have to worry about PF like you will though. Some of my friends that shoot matches use SPP and up the charge a 0.1 just to be sure but the last time I talked to them, they really didn't see a difference between LPP and SPP.

What PF is your ammo usually? if you have a buffer I would say let it ride. I haven't seen a different running N320 and standard SPP though. Can't say anything about how it affect other powders.

I'm using Titegroup right now, and yes there is a buffer. I'll just let it ride with a SPP rather than SMP.

I use SRPs in small primer .45 cases (Tula KVB 223) and did not notice any velocity change from LP cases with LP primers.

Same bullet, same load:

4 grs Clays

200 gr LSWC

1.250 OAL

I haven't seen a difference between magnum and non so I've never changed my charge.

I SPP for SS nats and they chrono'd the same as my regular LPP load

If I use standard CCI 500 primers I have to increase the charge between 0.1 and 0.2gr to equal the PF I get with the CCI 300. However, If i use the magnum CCI 550 primer, I get a higher PF than with the CCI 300 with the same powder charge. I usually don't sweat it, because I load to 172-175PF just to be sure.
