tpcdvc Posted April 29, 2005 Share Posted April 29, 2005 I'm wondering if there is an advantage gained by using small rifle primers instead of using the regular small pistol primers for 40 major. Advantages in recoil maybe? Thanks! Tim Link to comment Share on other sites More sharing options...
D.Hayden Posted April 29, 2005 Share Posted April 29, 2005 Search the reloading topics.. for me very little difference, but if you reload both rifle and pistol, you only need to buy one size primer, and you won't mix them up.. pistol primers in rifle (I've read) is bad...

Advantages in recoil maybe? Thanks! Tim <{POST_SNAPBACK}> from my experience..no change in recoil or velocity..the small rifle primer is harder and won't flow or flatten as bad with high pressure rounds.. on the converse side if your round is not high pressure enough..the primer doesn't seal as well and your get gas release around the primer and will get a gas erosion ring on your breechface.. what primers are you using now..and what do they look like..

Alan Meek Posted April 29, 2005 Share Posted April 29, 2005 I've always used Small Pistol Primers in my .40 loads Link to comment Share on other sites More sharing options...

tpcdvc Posted April 29, 2005 Author Share Posted April 29, 2005 I'm using SPP now. I load both a major load and a minor load in 40. I'm getting a new Bedell limited gun that for which I will have to work a load up. So, that is why I was thinking about switching. I imagine I will stick with the SPP since I will still load both major and minor and there doesn't seem to be an advantage and there might be a disadvantage for the SRP in my minor load. If I shot open I might go a different way. Thanks, Tim Link to comment Share on other sites More sharing options...
eerw Posted April 29, 2005 Share Posted April 29, 2005 I ended up pretty much using what I had...as I predominantly shoot open (SRP) or production (SPP). with .40 loads I have had no real problem with using either.. I do use Winchester for the small rifle and Winchester or Federal for the small pistol. Link to comment Share on other sites More sharing options...
sargenv Posted April 29, 2005 Share Posted April 29, 2005 I've actually started using Win SP for 9mm minor, 40 major, and 38 super major without any problems. If I switch over to Minor (ICORE) 40's I change primers to the Federal 100's since I have a lighter hammer spring. If I shoot 10 mm minor or major, I use the Federal Large Pistol primers. Currently my 38 super major load is 8.25 of SR4756 with a 130 gr rn Armscor bullet. I'm making major easily with this combination and no primer cratering or flattening. Initially I used Win SR's in the Super, but tried the SP's and haven't looked back. If I work up a load, I generally start with the Rifle primers and then swap out to the pistol primers after I've found my load. Seems to work for me. My Major load for 40's is a 180 gr RNFP Plated West coast (now something else) with 4.7 gr of tightgroup and 1.750" length. Vince Link to comment Share on other sites More sharing options...
MikeFoley Posted April 29, 2005 Share Posted April 29, 2005 I use WSR for .40 and get a little more velocity and a lot more consistent ES and SD. Link to comment Share on other sites More sharing options...
texasag93 Posted May 1, 2005 Share Posted May 1, 2005 SRP for all my 40 loads. As stated about, it is just easier to buy only SRP for all my 40 and 223 reloading. TXAG Link to comment Share on other sites More sharing options...
BismarckC Posted May 1, 2005 Share Posted May 1, 2005 When I started shooting several people were using Federal SRP. It worked for them and it works for me. Link to comment Share on other sites More sharing options...
Hey QuicksDraw! Posted May 1, 2005 Share Posted May 1, 2005 Winchester SRP as suggested by Brian for my fourty. Federals are too soft for me and I have blown a stack in my 650. Link to comment Share on other sites More sharing options...
Azone41 Posted May 1, 2005 Share Posted May 1, 2005 Using rifle primers in a .40 is not going to give you a true sign of pressure because it's made for higher pressure loads. .40 is so easy to make major that I don't see a reason to reinvent the wheel.

gobabygo Posted May 2, 2005 Share Posted May 2, 2005 I just switched to Win small rifle primers because they cost the same as pistol and I'll be loading major 9mm soon. I just chrono'd some of the same loads using WSR and WSP primers and the difference was extremely small. Like 10 fps though based on the SD the difference was statistically insignificant. The only benefit that I see is that I'll only have to stock one primer for these two calibers. Link to comment Share on other sites More sharing options...
Bear23 Posted May 2, 2005 Share Posted May 2, 2005 Federal pistol primers are all i use. I shoot revolver quite a bit and need something to accomodate both revos and my limited guns. I would see not reason to use rifle primers unless you are going 9mm/38 super in open. Link to comment Share on other sites More sharing options...
Jayson@IGF Posted May 3, 2005 Share Posted May 3, 2005 No need to use small rifle primers, but if you were to run out of small pistol and needed to you could use them. Link to comment Share on other sites More sharing options...
