Fgm215m... Just the cool thing to use. ??

[Aimsmall55]

I was at my gun builders shop yesterday getting my .300 throated a bit more. He did it and told me to prime him 4 cases. I did and all of a sudden he was like wtf!! Don't give me that shit man!! I was like what in the hell are you talking about? He said that the 215's were shit and that it was a fad. Then he pulled out some wlrm's. he said "these are the best primers out there for the .300 win Mag. When I asked why he simply stated that during ignition , lock time is crucial and the fgm215m sucked and in his 40 years of building and shooting world championships he knew a little bit. Well I was rolling on the floor laughing so hard I really didn't give it much thought. What do you guys think. I'm not trying to stir up a hornets nest here so if you want to cuss me
Or him take it somewhere else. Just curious if what he says holds any value with vet reloaders

The methods used to express opinions in this endeavor can be very caustic. I don't understand why but the name calling of someone else's choice is repeated over and over by enthusiasts, gunsmiths and 'professionals'.

IMHO and IME Your gunsmith, while presenting it poorly has a couple of things correct.

1. There is a difference.
2. There is documentation on the net about what the difference is.
3. I exploit the difference in how I load.
4. IMHO and IME Magnum primers are not "needed" in most magnum cases.
5. For hunting loads I use magnum primers in magnums but for precision/tactical I use regular primers.
6. IME there is 20fps between the GM210M and the GM215M for the same powder charge.
7. IME there is a larger ES for the GM215M no matter the powder charge.
8. I have put magnum primers in non-magnum calibers with reasonable results. If I were using a 30-06/308/Mauser derived caliber in sub 25degrees hunting, I'd probably use a magnum primer. Not necessary but just me.

To better share what I would do, please tell us for what purpose you use your rifle. Hunting, Precision/Tactical...

It's a .300 win mag with a 30" broughton and 2" shrewd brake with a trued 700 action Jewell trigger topped with badger ordnance base and rings and a NF Nxs 5.5x22mildot. I plan on shooting the 215 and 230 hybrids for recreation and occasional long range deer hunts. Basically, I got the rifle built for elr and throated for the big boys. I plan on running Retumbo or H1000. If I have to imr7828ssc. That's all up to the rifle. As far as the mans judgement, he set 4 or 5 world records in ftr and won a lot of world championships. I won't say his name but he was known as the "Ragin Cajun "

I try and use 215Ms in my 338LM, but I've also used WLRM primers and regular 215s, with good results.

Some primers have longer/hotter sparks than others. Some have harder cups than others. Some have better quality control than others and yield more consistent sparks from primer to primer, across a carton.

As long as they're working, who's to say which is better?

One can do a lengthy experiment and document the results, coming to an empirical conclusion, but life's too short, for me at least.

Agreed.

I use 215m's as well in my 338.... I did research online and it seemed like most people had bet results with their 338 loads with the 215m's do that's what I chose. I haven't compared it to others , but my 338 already gives me insanely low ES numbers , so it would be a waste of time trying others.

I ran out of 215`s a few years ago shooting a 7mm RUM,,I loaded 50 rounds with WW primers and had 4 hang fires in the first 10 rounds and pulled the bullets and started over with 215`s and have not had any problems since.

if you are loading much over 75-80 grs of powder and will be in cold weather for long periods of time I would highly recommend the Fed 215 primers..

Well I got cci's , 215m and wlrms. I'll probably stick with the 215s. Thanks for the input

I Use Federal #215 primers. I havent even tried the match version yet. I always hear that federal primers are the best thing to use. Im getting 33fps deviation out of my 300wm with h1000. 33fps seems good to me. Maybe its not. I use Winchester primers too just not in my 300. When I run out of winchester, Im switching everything over to Federal.

in my 223 CCI 400 is all I use,,but it is easier ti light 25 grs of powder than 90

I have some of the Federal primers of which you speak. I don't use them for a whole nother reason. In my experience once you use a Fed primer in a case no other primer will fit as tight. If you are gonna use them exclusively this is no problem at all.

The time has come in which due to shortages we can almost judge a load by the sound it makes, "bang" means you have a successful load.
I have never had a Federal primer fail to go bang. Federal primers causing a slower lock time? Not unless you are using the wrong primer not matched to the amount of powder you need to light, extreme cold, etc.
I call bunk on this. Some people end up emotionally invested in brand X over brand Y. It can be simply silly.

I don't hold any world records, but I can truthfully claim to be an FT/R master, having missed HM last season by .04%

Once I have a load that shoots, I've never been able to shoot the difference between primers...and I've tried.

I read a study regarding primers where they did accuracy testing and took high speed pictures of primers getting touched off. There were obvious visual differences with some being really bright, sparky and blow-torchy. Others kinda went poof.

The claim was that gentler primers were more accurate.

Kinda like how high octane gasoline burns slower than low octane, and won't detonate in high compression, or high combustion pressure engines.

Anyway, I've read and heard it enough times that I believe a discernible difference exists, but I haven't seen any rock solid proof of it - only anecdotes.

I certainly believe it does not matter to a tactical marksman.

ETA: There have been NUMEROUS reports over the last year of Winnie primers failing, leaking combustion gas, and gas-etching boltfaces. I am avoiding them.

Agreed on the silly part. I didn't mean to piss anybody off if my initial post came across as rude. Which, it probably did. I thought his way of expressing his dislike was hilarious but the more I thought about it the more I wondered. Thanks for the input fellows
