I have tried to run 200 gr SWC in my 21 and my 30s but have had issues. Most will cycle fine but every so often get a failure to go into battery and have to smack the slide to get things going. I do use a Dawson case gauge and they pass. Would assume my oal is off but can not find the sweet spot. These rounds work flawless in my 1911.
Have given up on Glocks and SWC and use FP or RN.
Maybe some smart guy will solve the issue and I can use them. I love SWC in competition as the "flying ashtrays" make the best holes.

They sure do make the best holes... :cool:

Only tip I can give is to do the "plunk" test to determine the best OAL for your gun... Take the barrel out and drop the cartridge in... It should "plunk" when it drops down the barrel (hence the name) and should spin freely... If not, go a little shorter...

I usually dump all the powder out before doing a plunk test... No sense wasting powder or primers for rounds that you won't shoot...

jb thank you sir, sound advise. I usually rely on my Dillon case gauges but the barrel is the final authority. Just ran 50 thru the barrel plunk test that passed the case gauge.
Will shoot on Saturday to see. Will update then.

Is your crimp tight enough ?

Although swc sabots are not known to creep, you may be having one or two being affected by recoil.

You could make a mold of the chamber using Cerro-safe and get an exact measurement of your chamber. A 1/2 lb block of the stuff is about $15 at Midway. And I saw another material in the Blue press a couple of months ago but I need to find the magazine again for the material.

That is waaay too much motivation for me. :cool: My 45's run perfect on any sort of RN or FP so for now will stick with them. Thank you for the input

That's mainly a precision rife or pistol shooting technique for reloaders. If you reload to SAMI specs then the 'plunk' test jb mentioned is just fine IMO.
But it is nice to know your chamber dimensions so you can better adjust your dies.

A friend and I used to have to do that years ago when we were loading 9x19mm for my BHP and his Glock 17, especially with heavy bullets, like the Hornady 140gr. .357 JHPs that some people were loading at the time.

The chamber in my Browning was much tighter than that in my friend's Glock.

I load the 200 grain SWC in both lead and plated bullets.

I load with 4.5 grains of Titegroup and haven't had any problems.

To be honest I've never measured OAL till you asked me.

My first father in law taught me to reload about thirty five years ago and he shared some tips and time savers with me. He took some rounds that he had been successful with and kept a few back to use as reference.

If I have to change the settings on my dies for any reason, I use my reference bullets to set my dies.

To do this, I put a reference round in the shell holder of the press and drop the handle. I then adjust the die to loosely fit the bullet and then fine tune from there. I load with a Dillon 650 so each caliber is on a tool head and it's easy to maintain the settings. If I have to change dies or settings for any reason, it's easy to do.

I only load a few different caliber and bullet types and keep one or two factory loaded rounds of each for reference.

The 200 grain SWC I mentioned earlier is a bullet I've shot in matches for years and have no problems with. Not very scientific, but it's always worked for me and I haven't blown anything up yet.

I'll add the customary legal liability disclaimer to use any and all load data and measurements at your own risk and reference published manufacturers information for accuracy. If you don't feel comfortable with any information provided, don't use it.

Bullet type affects OAL dimensions, I sometimes load a few and put them in the magazine and cycle them through the weapon,if they feed and eject ok then load away.

Yup, and car makers recommend only using their name brand oil and filters, and grocery stores recommend only buying their store name brands ...


Nothing new there.

And Glock does not recommend using lead bullets in their pistols.
Yeah, I think I read something about that back in 1988 when I bought my first Gen-1.
