Comment section: You shoulda coulda woulda... Blah blah blah. Good grief, all these overly critical idiots. Thanks for putting the time into this test. I found it interesting.
I consistently find with my chronograph statistically significant lower variation in muzzle velocity when using bench rest primers for bolt action rifles up here in Alaska.
The change in velocity can affect fine tuning of that particular load, I would evaluate velocity SD with 2 different powders(1 single based, 1double based).This could be done using a simple 30-30, 460SW, 44mag. Only maths of a good chronograph can tell the truth. Shooting groups has to do with accuracy, accuracy comes from repeatability, this is what a primer can affect. Nice video anyway as you have put speed data. 👍🏻
Great comparison I’ve been looking for some comparisons like this for primers. specifically 308. what powder did you ever go with? I recently Reloaded 168 grain VLD 46 grains varget and federal 200 primers was getting averages of 2724 in 20” ar10. And 2716 in 22” Remington 700
Interesting spread between the primers, I haven’t tried my reloads yet I’ve been loading a shit load of 30.30, with three different primers and three different powders. Primers,br-2, rem210, and Winchester regular large rifle. The powders are 8208 xbr, leverevolution, and H335, bullets-flatnose sr, round nose Hornady, and the 160gr ftx. All loaded at midrange charge. I am new to the reload game, and I am hooked 🤷🏽♂️👍🏽💪🏽
@@RichardBeauchampTV from a bench rest no, but they all go bang and hit steel target 🎯. i’ve loaded over 300 rounds with all those different powders. i can’t really complain over the loads. shot them while standing. the recoil wasn’t bad at all. my next future loads will be 170gr bullets, when i find them. hard to find bullets right now.
@@alejandroflores-samaniego9320 I am having difficulties finding bullets too. I am looking for Barnes Original FP FB in 190 Grain for the Winchester 30-30. I want to load some bear defence and moose thumpers.
@@RichardBeauchampTV i didn’t know they made that heavy of a grain for the 30.30. that’s pretty cool. i am pretty sure loading a 170/160 grain hot might work well on brown bear. i’ll have to look at my loading books for that heavy bullet your looking for.
My FA Perfect Seat Hand Primer docs says the primer pocket of 308/7.62x51 is 0.2085 " which seems to be correct while the CCI no 34 primer measures on average s 0.211" . They are a very tight fit. Almost scary how much pressure it takes to seat them. I am waiting for a primer to take off on me but hope they dont.
@Copper Pill Reloading Did you start this test with the current best load workup for your specific rifle? If not, what did you expect to learn, without a standard, or control sample to compare too? Extremely new to reloading, and I am missing the thought process.
I believe his purpose was merely to show effects of different primer on identical loads, not necessarily which produced the best group. In that case, it really doesn't matter if it was his best or worse loading, just the differences in "that" load depending on primer used. Changing any component can invalidate any "best" load.
Hey CPR, Interesting video. I did one similar in 6.5 Creed here: ua-cam.com/video/ypI6D-i57uk/v-deo.html I am interested if you do some more work in this arena what you plan to do next. I have banged my head against the wall to think of a realistic test that takes into account the most factors and not shoot 1000 rounds to decide. What I found though too is that Magnum primes almost in all cases give me better velocity statistics, as always YMMV. Thanks for your efforts!
I’m definitely going to to do a few more videos in this series. 5 round groups is certainly the bare minimum when doing testing like this. It provides but a peek through the window at what your widespread results will. Of course there are many other variables that come into play, but I like to keep it simple as possible. I may do a magnum vs standard primer comparison in the future. I’ve always wondered myself and it’s a very common question online. Thank you for he feedback!
Just what I needed as I was looking for primers on a website and couldnt decide which is correct or best. Thanks so much.

Alejandro Flores-Samaniego, Are you able to share your results with these loads?

this test will not work unless you have a load that already shoots 1/2 in or less....waste of resources and time
Need to measure from o jive rather than COAL when seating bullets. Get way better consistency that way. Need to get the bullet comparator gauge.
When he fine tunes a load for that chamber, yeah, but he was using the published COAL to get apples to apples data.
And use RE15, 42grs
When you do a test like this use match grade bullets, FMJ bullets just don't do it, time for a retest.168 ELDMs

What's your primer seating depth ? Factory spec is 0.004" below flush my groups are better at 0.007" .. Some like 8 to 10 Thousandths deep..
