What do you guys use? I know when reloading for cartridge firearms I played with them quite a bit and sometimes I think they made a pretty big difference. I only remember one conversation on primers and it was over using standard vs magnum. I use Fed Gold Metal magnum because it seemed to be the best for my long range gun. I certainly have more testing to do before I start switching primers but it’s something I am thinking about.

If you have some you are good, I use federal 215s but have used CCI and Winchester Magnums as well.

Whatever is available . I cant tell much difference with a large rifle primers . 209 primers big difference.

From the sound of Joel's post, it seems to me he was more concerned with LRMP's than standard LRP's and not so much the brand? I did some testing a while back and can't recall the exact results but since I am now using only LRMP's I must have concluded that they produced better or more consistent results. I may have to research my "loose leaf" spread sheet and see if I can find it! Like Bill, I use either Fed. 215's or CCI 250's.....Both magnum primers. Found the post: It appears that the standard large rifle primer shot as well but produce about 20 fps less velocity. hanksmessageboard.freeforums.net/thread/3216/magnum-standard-primers |

It was posted with inent of trying to figure if people are exploring different primers LR or LMR and different brands. It makes complete sense when one goes to some of the slower powers that magnum primers would be used. It’s just in cartridge reloading type and brand are almost always stated but in the SML world we seem to use what’s at hand. That kinda struck me as odd. For precision I’d always leaned towards gold medal or Benchrest when I had the chance. In some loads it did give me a measurable advantage others it was only confidence. In closing it just seems I had payed a lot of attention to primers in the past and now with SML they just don’t get much attention.

I certainly know you have shot way more SML than I have and the statement seems to hold true in minds of manny. That statement is exactly what I am having a tough time to get my head around. |

Joel you may have a very valid point . With 209s Whinchesters are much dirtier than Federals and federal 209 primers would give me a additional 30fps .
My statement honestly was ignorant . I really have not tested Whinchesters/Federals or others for that matter. It just so happens this week I switched from Whinchesters to Federals only because I was buying powder and saw they had Federals . They were not the gold Federals . I can not tell a difference in the groups I have shot so far Federals vs Whichester.
Tell you what . I'm gonna wring this .40 out . I'm gonna spend some time developing a load . After I get what I think is my most accurate load . I'll try to buy different brands and see if it makes a difference . Maybe it does ? I would sure think if it makes a difference for you bench rest guys it should for this game also ?
Gee thanks Joel something else for me to worry about ! ! !

Pretty much standard practice is the use of LMR primers, so far I have not seen anyone fine tune their load to the point of seeing if different brands affect accuracy, It will be interesting though. Until very recently LMR match primers have been pretty much non existent, they are still hard to find in my location, I feel fortunate just to have a good supply of Federal 215s. I do know that the federals require a lighter primer strike to ignite, that's the reason I use them.

Doug that wasn’t intent but your welcome. 😁
Just a newbie looking from a different angle.

I have only used regular primers. I didn’t have any magnums is when I got my muzzleloader and they worked fine so I have never changed. I have never shoot in very cold conditions so that could change my mind. I have used federals Winchester and CCI all with good success.

Magnum primers are recommended because we use large amounts of rifle powders. You need a lot of heat to ignite 78 grains of powder, now if your shooting a break action and or reduced loads of 55 to 65 grains of powder you can get by with standard rifle primers.
Brands of primers have never made a difference to me and I tell people to use what ever is available in their area as I don’t believe it makes much difference.

I’m new to this game so take this with a grain of salt. I shot a lot of .375 H&H back in the day and found that LRPs were more accurate than LRMPs, about .5 to .75 MOA. Principle is that LRPs ignite a smaller pct. of powder charge than LRMPs each shot which produces more uniformity from shot to shot. 6mm BR was developed with a small flash hole based on this principle.
My question is has anyone done extensive testing to see if this holds true with SML?

I currently shoot Federal 210 Match (non magnum) primers.
I have experimented with both magnum and non-magnum primers and have found the non-magnums to be more accurate out of my TC Encore 45 cal, HIS smokeless.
I am shooting light loads, 56 grains of 4198 with a Pittman 275 AccuMax
Good luck

This old guy only use 209, no modules YET for SML. However in my 6.5 CM I did find that the Federal 210 gave the best consistent accuracy. Tried mag of couple brands and the accuracy was better with the federal match primers. had to use the tape but measurably better by .25 to .4 moa depending, as usual notable out at 300+. JMHO and experience, others will differ. 10
