Wait!!!! You shot someone else's reloads and lived to type about it? Impossible.
May a trade on here a year or so. Finally got around to shooting the gun with his reloads and it seems to be a good recipe. Only difference for me is I don't have but around 150 of his brand primer(cci 250). What I do have though is around 6-7k win mag primers and about 1k federal 215M. Would I notice any noticeable difference in yalls opinion??
There must be a standard threshold for ignition, maybe Winchester will show the greatest variations, both will work well.
Primers are no different than gun powders. They all have a different burn rate. You can Google primer burn rate chart. What caliber are you shooting? I use Fed 210M's for my 7 mag with 180gr eldm. The 210's tighten up the group over the Fed 215's.May a trade on here a year or so. Finally got around to shooting the gun with his reloads and it seems to be a good recipe.

Yea I googled it, maybe not precisely what you said but it still showed different results on each article I read. I'm not sure anyone knows honestly lol.Primers are no different than gun powders. They all have a different burn rate. You can Google primer burn rate chart.
Yea I'd love to be able to do that, but I left my labradar in Ohio and I'm currently in Louisiana. I'm just going to wait until I get all my stuff together and then give it a go.Try backing down a couple grains and use what you have. Check velocity. spread, and POI.
I do not have any way to do that. Any time I am trying a new configuration, I pay particular attention to how the bolt feels when I go to lift it after firing and then when I remove the brass I check the primer and case for any signs of excessive pressure. The only time I have had a substantial problem with pressure with any loads in these two guns was when I was attempting to bring solid copper bullets up to the speeds I was getting with HPBT jacketed lead bullets. Which BTW, did not work well. I still like the solid copper bullets but they do result in more pressure. I still have not fully figured out why, but I know I am way off topic now.How do you compute the cylinder pressure?
I'm only asking about pressure changes. From Hogdon's load data sight. And typically they use a given primer with a given powder, like Ramshot powder uses Winchester primers, Winchester powder uses Federal primers in rifle loads. How fast powder is ignited will change how it performs. Not just velocity, but accuracy too. I lack the experience most of you have, so I read and ask questions. I recently emailed a bullet manufacturer on their load data as they didn't identify the primer used in their loads. Crickets....The only time I've ever seen a significant change caused by primers was when I tried CCI BR primers instead of magnum primers in my FTR rifle. The magnums worked much better. It went from a sub moa rifle to a 36"-48" rifle at 1000 yards. It was severely worse.

I've found with testing using short barreled contenders that the 215 and wlrm were similar with fire delivered and soot, but the 250 was very sooty and slightly milder compared to the 215 and wlrm. As far as the o.p., I'd probably use the wlrm and not look back, but the load may need to be tweaked a bit... likely not. As long as a primer is properly sensitized any proper strike should be fine.I would consider a possibility that different primers will either be better for you, or worse.
It probably won't be the same.
I suspect the abstract in this comes down to striking -that is optimum, or not, for any particular primer.
If so then striking could be optimized for a chosen primer.
Just a theory
