Can't find any CCI Large Pistol Primers #300 for 45 Colt

[VMass]

I haven't been reloading very long, but have been using CCI Large Pistol Primers #300 for my 45 Colt reloads with reused brass, about 5.7gr. of Titegroup powder and a 250 gr. lead RNFP bullet. That load is working just fine for me. Unfortunately, I'm running out of primers and, I suspect like many of you, I can't find any CCI #300. Has anyone had any experience with Remington Large Pistol Primers #2-1/2 for their 45 Colt reloads? Thanks in advance for your feedback.

Although some here will disagree, large pistol primers are large pistol primers regardless of manufacturer. I use CCI, Wolf and Remington.

Any LPP will work… TiteGroup is not particularly picky about primers.

In these times many of us make do with what we have on hand. PS i like loading 45 colt too.

I like loading 45colt as well 285gr cast over 18 gr of 2400 with what ever primer is handy. Winchester currently.

Do you ever change or check loads before or after changing primers? In the old days I just went and got some of the primers I used, now is a different story with availability.

During these hard times ... the rule is load with whatever primers you can get your hands on .
Over the last 50 years I have used every brand of US made primers , even S&W's Alcan brand . I mostly used CCI's because they were available , but have used Winchester , Federal and Remington . Recently a sale got me some primers made by S & B (Sellier & Bellot) they don't seem to be USA made but ... all of these brands seem to work just fine . Not one primer has failed to go bang ... although I know bad primers happen ...it's not a big problem ...yet !
Get whatever brand you can get your hands on an keep on Keeping on !

Light target and mid-range loads I don't bother checking pressure but check accuracy .
Maximum or Near Maximum and +P loads I drop the charge back 05% and test for pressure and accuracy . When in doubt , err on the side of caution , drop back and work up slowly looking for signs of pressure .

Only if I was to jump to a magnum primer or I was near max. I do look at manuals and see if there is published data with that primer.

oooh yeah… Primers swapping is a reality now

Nope.

However, I have only been chasing tight groups in handguns.

Rifle guy will surely differ.

I am from the same camp.

I use what I have on hand. My powders are primarily HS-6, AA5 and 7. Most bullets are home cast in the 250-300gr range. Brass is Starline because that was what was available. Primers have been CCI, Win, Rem, Fed, S&B, and Fiocchi.

They have all performed well and have put meat in the freezer. If I were to use what I have the most of it would probably be Win, but like mentioned they all work. Just make sure of your loads, start reasonable, and enjoy.

Use what you can get your hands on. These days, that ain't much.

 

[sparkyv]

FWIW, I've used WIN LPP, CCI #300, and REM 2 1/2 primers interchangeably in my 44 Mag handgun loads, VMass. The difference is not noticeable in handguns especially since I mostly shoot offhand, but for accuracy rifle loads, I work up the load all over again.

Not normally... but it would depend on the load, and the primer. If I was running a max load of W296, for example, I might back it down a grain, introduce the different primer, and do a short workup on it. Likewise, if I had to swap from a standard primer to a Magnum primer, and I was near max... back off and work up. Part of that also has to do with the powders I normally work with... Unique and IMR4227, which don't seem to care what primer I use, and I don't normally load them to max, anyway.

In the OP's case... that is, TiteGroup in that big .45 Colt case, which I have loaded as well... I would swap it and move along. I load TiteGroup at max data in the 9mm, however, so if I was changing primers, I would probably drop down .2grn and work back up, as a safety precaution in the very small volume 9mm case.

I agree with those who say primer brands are interchangeable, unless you have a reduced power hammer spring. Many cowboy action competitors lighten their hammer springs, trying to make cocking faster. Sometimes they get the spring so weak it won't ignite the harder primers. Since your gun functions ok with CCI primers, you shouldn't have problems igniting Federal or Winchester primers, which are a bit easier to ignite, in my experience. I can't comment on other brands. If you can, get a sample of the new primer from a buddy, put it in an empty case and make sure it goes bang in your gun before buying thousands of them.

If you can't find the primers you want load the ones you can find. Like said above, a LPP is for the most part a LPP. Load um up...

Agree - I normally have used CCI but recently got a great deal on a brick of Federal LPP's so those will be next when I run out of the CCI's. I don't anticipate any difference.

I disagree

First Rem & Win only make 1 each. Covers all LP.

CCI & Federal make 2 LP each. . I cant see them being the same?

Ball powder in magnum pistols may do better with a magnum primer. Think W296 & H110.

I use magnum primers if warranted. That's not the question. Standard primers are standard primers. Magnum primers are magnum primers.

Interchange all day with pistol.......rifle for hunting I keep it exactly the same.Freezer filling is serious business for me.

I stand corrected.

My chart at link has the WLP listed as Large Pistol (LP). Being as i have always used the WLP with W296 & H110, thinking its more a magnum then standard primer.
