Large Rifle Primer Evaluation using 308 Winchester

what do you consider the best one. i started reloading and cant find any but 9 1/2 in large.

My book calls for mag primers. I use mag or mil spec.

Would you recommend using the Winchester Large magnum rifle Primers and Varget with 178 ELDXs? Has anyone used these primers and had good groups?

I’m curious why you didn’t use CCI for FGMM.

I'm starting to reload and find your channel super awesome! Do you perhaps have any experience with Sellier and Bellot cases for reloading? Lapua cases are extremely expensive her in South Africa.

I would be really interested to see some study of primers versus altitude. With the lower levels of oxygen at which I live (7,200) I suspect that I should be using magnum primers where others use normal primers. I think my loads need the extra kick in the butt for full oxidation.

I managed to find a few hundred CCI 7.62 nato primers and I've heard they're a hotter then normal large rifle primer so that got me wondering if they could be used in place of magnum primers???

Hi! Question: If you find good combination of powder and primer. How much this "good finding" can be effected with change of bullet? or change of brass? would you say it is rather universal or if I find good combination when test are done with Hornady 155 gr. it can not be taken into Scenar L? of course I understand that amount of powder will change for different weight... but will good combination of powder and primer stay? thanks in advance for answering. This is really great channel.
regards

How long was the barrel?

I would not buy anything with a Remington name on it today. . .

Great

I wonder how the CCI primers would have stacked up.

I would like either a video or your comments on a situation where you have only one primer available to you. Then how do you select the right rifle powder based off the test results of the first powder you selected?

Good ol made in Australia Varget

Federal Gold Medal Match primers best primers ever for 308

Im using 168 grain hornady bthp
8208 imr and im wondering are 215m primers to hot. Assuming I stay at suggested 39 to 43 grain powder charges

Great video, as usual! ! I also have QuickLoad (QL) and something I'm seeing on a given load is that case volume will have an effect. I'm see a difference of + or - 1 gr/H2O on the Starline brass I'm using. Have you volume tested any of that Lapua, and if so, how did it look?

I'm curious what the small rifle primer test would end up being with Varget.

another well thought out informational video - thanks.

Because you had what you consider sub optimal results with CCI primers in the past is no reason not to include them in the head to head test here. Also, which primers did you use? I’ve achieved an SD of 4+ with Varget, Lapua brass, SMK 168gr projectiles and CCI benchrest primers in my MDT ESS Savage 308.

Why no CCI primers???? for small rifle, the Remington 7 1/2 is best in all I have ever tried, but in large rifle, either Federal 210M or CCI BR-2 or standard CCI primers rain supreme, and you do not have either of them. I have never had luck with any Winchester primers. WE had a gun shop that only dealt in match rifles, and the only primers he carried were Federal 210M's, CCI standard and BR-2, and Remington 7 1/2 primers.

Those S+B's sure look good. Your visual images and narration are very enjoyable to learn from. Thanks for taking the time. Have a good Sunday.

I am surprised that CCI primers were not included in the testing.

You really need to use small primer brass it vastly improved my 308

The most consistent I've found (but can't get anymore) are Tula primers, stupid hard cups though.
As far as the primer comparison, Mic McPherson did a huge test showing which primers were hotter, consistent, etc.

Thank you for looking at Winchester primers

When fire forming new brass my SDs are almost always terrible regardless of the brass brand or caliber. For that reason, I don't put a lot of stock in the initial velocity readings. However, on the second firing I know I'm going to get the headspace and neck tension I want.

Good video and information. I load my 7.62 x 39 . Tried some Tula using a couple different powder. And use some rem large primers and had much better grouping than Tula . So primers can make a big difference. Thanks for your videos

Who would have thought S&B primers would be that consistent.

Varget is a bit fast burning for 30-06, IMR & H4350 is a lot better suited. I used to use Varget, until I tried the better suited powders.
S&B primers look to be great!
Thanks!

The way things are now if you can get your hands on any primers you better grab them up. All the stuff going on has ammo and reloading supplies in short supply.

I'm #1, I'm #1, I'm #1... :-)
