B.Reid Posted June 24, 2008 Share Posted June 24, 2008 I don't know about the rest of you but I've had a problem locating WSR primers which is what I use in my Limited, Open and AR setups. Therefore I'm gonna have to consider another brand. Federal, CCI, etc. I would like to know what some of you are now using and how they compare to the Winchesters. Thanks.

Jaxshooter Posted June 24, 2008 Share Posted June 24, 2008 I have used Federal and did not notice any difference in 40 or 9mm major. Link to comment Share on other sites More sharing options...

shooting for M Posted June 24, 2008 Share Posted June 24, 2008 Wolff, but I had to change to a 17lb hammer spring in my STI, but the old one wouldn't work w/any SRP. BTW, changing to Wolff primers has lowered the standard deviation on a few friends loads. Jason Link to comment Share on other sites More sharing options...
jasmap Posted June 25, 2008 Share Posted June 25, 2008 I used the WOLF small pistol and I loved them. I had no problems and they kept the deviation tight. Link to comment Share on other sites More sharing options...
davidwiz Posted June 25, 2008 Share Posted June 25, 2008 I've been using Federal Small Rifle primers for .40, Super, and .223 and never had a problem with them (since '95). The Federal primers are considered the easiest to ignite (I believe the CCI are among the hardest). Link to comment Share on other sites More sharing options...

As mentioned above, I have noticed a reduction is deviation for some loads. Wolf SRP's are had to find now, too, unfortunately. I think Widener's is the last place to still have some of these primers in stock. Link to comment Share on other sites More sharing options...

Glk21C Posted June 26, 2008 Share Posted June 26, 2008 I couldn't get WSR primers so I tried CCI SRP in my open gun. I noticed absolutely no difference in velocity and all went "bang" as I hoped they would Link to comment Share on other sites More sharing options...
dajarrel Posted June 26, 2008 Share Posted June 26, 2008 Just recently bought some WSP because the WSR aren't available. I don't expect to be able to tell any difference between them. jmho dj Link to comment Share on other sites More sharing options...
Thomas Moore Posted June 26, 2008 Share Posted June 26, 2008 I don't expect to be able to tell any difference between them. in an open gun or compressed load you may see up to 50f/s slower. Link to comment Share on other sites More sharing options...
larry cazes Posted June 26, 2008 Share Posted June 26, 2008 I use Winchester SP and SR interchangeably and see no statistically significant difference in velocity. All of the variation I have seen is in line with what would be expected lot to lot. Link to comment Share on other sites More sharing options...
shooterbenedetto Posted June 26, 2008 Share Posted June 26, 2008 I switched to CCI and so far they are all going bang! CCI is $3.00 more per 5000pcs. over winchester from powder valley. Link to comment Share on other sites More sharing options...
Thomas Moore Posted June 26, 2008 Share Posted June 26, 2008 i just got back from the local gun shop during my lunch hour and picked up a hundred each of cci and federal small rifle primers. i will have them tested over the weekend to see if they produce not only the same velocity but they need to be accurate as well.

SLM Posted June 26, 2008 Share Posted June 26, 2008 I just bought 10,000 WSR primers a week ago from my local shop. Are they really that hard to find? RE:Wolf... A friend of mine called them to see what they would recommend for our game. They stated that the small rifle magnum would be the best if you want a slightly harder cup as there is no difference between the cups on SP and SR regular primers.

Thomas Moore Posted June 26, 2008 Share Posted June 26, 2008 there is no difference between the cups on SP and SR regular primers. what about the amount of explosives? Rifle primers are supposed to be hotter giving you 50-100 feet more per second. Link to comment Share on other sites More sharing options...

Rifle primers are supposed to be hotter giving you 50-100 feet more per second. Don't know who told you that. According to Winchester tech support there is no difference at all in the amount of explosive between rifle and pistol primers. The cup is harder on the rifle primer to prevent slam fires on military rifles that are prone to it. Thats it. There will always be lot ot lot variations, though.

al503 Posted June 26, 2008 Share Posted June 26, 2008 I've tested wsp, wsr, wspm primers. I don't have the numbers in front of me but the rifle was about 1-2 pf hotter than the pistol in minor loads and the magnum primers were about 3-4 pf higher than the pistol. The magnum primers were about 3-4 pf higher than rifle primers in major loads using very slow (sp2, 3n38, n105) powders. BTW, you can make major in 9mm in a shorty with poppleholes using n105, 125 gr bullets, and magnum primers. They were a b*tch to load without slinging powder all over the place and it honestly didn't feel as good as 3n38 or sp2 at the same pf. Link to comment Share on other sites More sharing options...

I don't have the numbers in front of me but the rifle was about 1-2 pf hotter than the pistol in minor loads Considering how much measurement error there is in consumer chronos and the additional lot to lot variation of the primers, this is not a significant difference.

Thomas Moore Posted June 29, 2008 Share Posted June 29, 2008 (edited) So I went to the range today to do some testing and I was surprised to find the results weren't what I had expected. I tested the exact same loads with four different primers. Load data 9mm 1.155 OAL 7.9gr 3n37 124gr jhp Montana Gold Primers used in this experiment. Winchester Small Rifle Winchester Small Pistol Federal Small Rifle CCI Small Rifle All three rifle primers were between 166 and 167 power factor. I shot three round average three times for each primer for a total of nine rounds. The small pistol primers came out to 165 to 166 power factor, not really a big difference. Then I decided to perform a group test and that is where I didn't think the small pistol primers would be better than all the rifle primers. Take a look at the attached pic. The top row is WSR, the second row is WSP, the third row is FED SR and the fourth row is CCI SR. I think I may be using small pistol because it's giving me the best group. All shots were fired from and block of wood and a sand bag, perhaps a ransom rest would have done better. The distance was 20 yards and five shot groups except for the bottom row middle group where I bumped fired and shot just above the "A" Edited June 29, 2008 by Thomas Moore Link to comment Share on other sites More sharing options...
