Match vs Regular Primers?

[Jaxdialation]

The communication medium isn't really under discussion. And individual responsibilities for determining the voracity of claims are the same regardless of what is communicated and how.

I'd be interested to know if Federal has ever indicated that there is anything better about Match primers. I don't think they've done this.....they just mark them Match and let us interpret. If they actually said "these are better because ......" I'd be inclined to give the matter a second thought.

Germán Salazar's article was on my mind as well, but could remember the name.

The internet is the preferred medium to flow the available information whether we like it or not, like we are all doing here at the moment and it's entirely up to the individuals to sort the validity of the information for what it is worth; what an individual does with it is their responsibility.

I agree but you noted "internet expert" when none of them made on the link I provided made such as claim.

Anyways, here's one C&P from CCI's site (CCI Ammunition - Primer Details) ...

In benchrest competition, there's no such thing as a group that's "too small." Everything has to be tuned to the highest degree to produce match-winning results. That's why we make CCI Benchrest primers. Only our most experienced skilled personnel put the priming mix in the cups, so you get the same flame, shot after shot. We also use specially selected cups and anvils for added consistency. An independent researcher identified the use of CCI Benchrest primers as one of two factors that were the most significant contributors to tiny groups. We can't add much to that!

Can't be that much difference from Federal's claim. gun)

Savage 26" heavy barrel .223

Here are some loads with Varget and JLK 65 grain VLD's and different primers.

The powder charge of 27.5 grains usually produced velocities in the low 3200s in this 26" heavy barrel Savage .223. The primers used are as follows: Federal 205 and 205 M, Remington 7 1/2 Bench Rests, CCI BR 4 and 450 magnum and Winchester WSR. All groups used five shots at 100 yards.

Federal's 205 made three groups. They measured .519" @ 3220 fps, .962" @ 3224 and 1.216" @ 3210". The 1.216" group had a couple of fliers. They averaged .899" @ 3218 fps.

The 205 M from Federal is a match primer. There are records for four groups. They show groups of .709" @ 3224 fps, .726" @ 3224 fps, .644" @ 3224 fps, .757" @ 3227 fps. Their four group average was .709" @ 3225 fps. This primer produced the most consistent velocities that I have seen in any firearm.
Consistent velocities did not translate into the best accuracy, though.

The four Remington 7 1/2 Bench Rest primer's groups measured .744" @ 3211 fps, .682" @ 3211 fps, .676" @ 3224 fps and .682" 3223 fps and averaged .696" @ 3217 fps.

Winchester's WSR primers worked as follows: .582" @ 3220 fps, .399" @ 3249 fps, .830" @ 3219 fps and .812" @ 3219 fps. The average for WSR is .656" @ 3227 fps. All of the WSR primers were pierced by the firing pin.

The next primer is the CCI 450 magnum. It produced .684" @ 3200 fps, .546" @ 3207 fps, .711" @ 3234 fps, .544" @ 3219 fps, .806" @ 3191 fps and .525" @ 3218 fps. The average for the magnum primer was .636" @ 3211 fps.

The last one tried was another bench rest primer. It is the BR 4. We saved the best for last. The groups measured .492" @ 3245 fps, .477" @ 3250 fps, .441" @ 3245 fps, .452" @ 3232 and .460" @ 3229 fps. Its phenomenal five groups average is .464" @ 3240 fps. It also produced the highest velocities.

With the same rifle using the same powder firing the same bullets groups with the "best" primer are half the size of the worst groups.

When I tried the 52 grain JLK's I tried only two primers: the Remington match and the standard CCI. After eight groups of five shots with each primer the standard primer's groups were about 3/16" smaller on the average than the match primers.

Its my understanding that the various grades are based on testing similar to .22 ammo. If a lot comes off a machine and tests in to a higher consistency it gets assigned the more expensive "match" packaging.

You guys are all wrong. There is a difference. About $20.
