I have heard tell that some folks use small pistol primers in the Hornet to achieve better accuracy. I don't believe I have ever tried this. I have a variety of both small rifle and small pistol primers including Fed, Win and CCI as well as BR4s. I'm looking to try and get good consistent sub MOA groups from my Rem (Zastava) Hornet.
I have achieved right around the MOA mark with 40 gn V-max and L'il Gun powder using CCI 400s and W-W brass. I would like to do a touch better if it's possible. To that end I trimmed and chamfered all my fired brass last night, (super PIA with hands the size of mine, and I had to modify my trimmer to get it to go that short) and am now down to the priming stage but would really like to know if there is any factual data to support one type of primer being more accurate than another.
Anybody out there that has proven or disproven this small pistol hypothesis? Or how about the BR4s?
 
Douglas, I was using pistol primers in my Brno Hornet, with Lil Gun powder. I forget the bullets, but 13 grains of Lil Gun was the standard full power load. I found about one in four primers would leak.
Changed to rifle primers and they didn't leak, but I could not detect any difference inaccuracy, between pistol or rifle primers.

Remington 6-1/2 primers were specifically designed for the 22Hornet, and they worked excellent in my rifle. I found better accuracy than with other rifle primers, and no leaking primers.

From the Remington site.

This 6-1/2 Small Rifle primer is primarily designed for use in the 22 Hornet.

I was concerned with this Bruce as I am maxed out and not using pussy loads. I was concerned with piercing and leaking with SP primers.

No hope of finding Rem 6 1/2s anywhere around here I'm afraid there SJ.............
 
I am getting sub moa (1/2") groups in my Browning A bolt using a load provided to me by Dean2 on this site. 2900 fps

Federal #100 small pistol primers, 40 gr Hornady Vmax, WW brass. No primer piecing. Also use Sierra 40 hp with same results.

This load is hard on gophers.
 
I just phoned the LGS on the off chance and you'll never guess what he said..........he has 3000 Rem 6 1/2s.........at the paltry sum of $70.00 /1000, anyway gonna buy 1000 and give them a try........Thanks for the tip there SJ !!!!!

Think I may try some small pistol (have Fed, Win and CCI I believe) as well and some BR4s, just to see where the bear REALLY sh!t in the buckbrush...............
 
All the references I have seen to Small Pistol primers have been in relation to cast bullet loads.

Apparently the SR primers are lively enough to unseat the bullet from the case prior to the powder being fully ignited, or some such theory. The less lively SP primers are supposed to be a solution.

I would think that it would depend almost entirely, on how hot-rodded the loads are too. Some guys shoulda bought a .223 instead of trying to load a Hornet into one, eh? :)

Why use pistol primers, when Remington sells a primer designed specifically for this application?
 
Not really hotroddin' there TJ, just loading to the upper end of the books as that's where my best accuracy seems to be.......


Hey there SJ, I just drove through Camrose a few days back.........just noticed that's where you hail from.

I moved here in June when I retired. I actually have about 1500 Rem 6-1/2 primers on hand, and I no longer own a 22Hornet. My best accuracy was with 12.5gr of Lil Gun behind the 40gr v-max.

I'm working with seating depth now, but I'm limited by my magazine............

I had to snip the very tips off of the 40gr v-max to use them in the magazine. I took off just enough to get them to fit, and it didn't seem to noticeably effect 200 yard groups or point of impact.
 
My most accurate load in the Hornet was 12.0 gr of Win 296 with a 40 gr Nosler Balistic Tip and a CCI 550 primer. OAL= 1.775", shooting just under one inch three-shot groups at 200 yards in my Brno ZKM 465.
The switch to small pistol primers was an experiment, as this rifle was having some difficulties producing really good accuracy. It seemed to tighten up noticably after switching to small pistol primers. That said, I did experience two pierced primers in a Browning Low Wall with this same load (none in the Brno).
Another variable that seemed to help was to seat the bullets so that they were "just barely" held by the case neck.
Magazine length was an issue, which I addressed by loading only for two rounds in the mag, one in the chamber.
 
I have tried both Small pistol and small rifle and as far as accuracy goes I see no real difference.
What I did find though is the small pistol primers the velocity was more consistent.
I have been using H110 and Lilgun at full listed charges in a Ruger 77/22 Hornet with Sierra 40 gr HP bullets.

I have mostly used the Remington 6-1/2 primers in my Anschutz. But it is a very fussy rifle and kinda drove me nuts trying to find loads it really liked. Some combinations were good, some so-so, some poor. Pistol primers, regular small rifle, different bullets and powders, No consistent pattern that i could tell. Then I tried a Win factory load with their 46 grain HP bullet. 3/4" 5 shot groups!! So now I'm trying to exactly duplicate that load, with all Winchester components. The powder is going to be the biggest challenge, since the Win factory probably don't use canister grade powder. W296 isn't quite right for this load, so I'm going to try AA1680 and Lil gun next.
One word of advice from my experience - the Lee collet size die is your friend with this cartridge. The thin brass, often generous chamber size, means you get better case life and accuracy with the collet sized cases.

I am using a Redding die set , Lil Gun, 6-1/2 primers, Remington brass, the 40gr v-max, and my Anschutz 1730 HB will put 5 shots into 1/2" at 100 yards.
