Just dros'ed a glock 20sf

[Bobby B.]

So I just jailed a glock 20 sf 10mm; am looking forward to picking it up soon.
Any thoughts/real world use on the following?

-- Lone wolf 6" barrel -- Not for most usage, but I am looking forward to planning an Alaska backcountry trip in the future and this would be what I take. Anyone have any positive/negative experience with these?

-- Commonly available ammo? While I would like to learn to reload, and this would be great caliber for this, has anyone felt more comfortable with any brand over the other for factory stuff? Obviously don't need hot loads for range-type usage, but would like to start out with something common for this and perhaps some jhp.

Thanks in advance.

Underwood ammo would be one of the hottest load there are. They push velocity around 1400-1600, depending on grain/load. Pricy though at around .75 a round.

Armscor is available since you are SoCal (Turners) at around .55 after tax. I think at around 1150 manufacturer rated velocity. I have not seen any locally cheaper than that, so online would be the cheapest.

You can also shoot .40sw through (Glock style pistols only, 29/20) with no modification.
Let's not debate this topic here (the horse has gone missing). Let's just say many people do and works perfectly fine at their own risk.

I know velocity is not the best indication, but it's will kind of tell you how much a pop you will get.

Congrats on your 20! I've probably run through close to 1.5k reloads with the stock barrel and it has been running flawlessly. I also run .40sw through the same barrel with no issues. Look into Lone Wolf's, Barsto and Storm Lake conversion barrels if you plan to run other calibers as well.

For ammo choices, Underwood will probably be your best bet for full power loads from a availability and price standpoint. They have a great selection of ammo from their 135gr Nosler @1600 fps or their 220gr hardcast @1200 fps at relatively affordable prices. There are also various companies that sell lower powered reloads (180gr ~1100 fps) like LAX, Georgia Arms etc if thats more your thing.

Now the biggest savings comes from reloading the 10mm. $30-35 a box of full power gets old really fast even though that is cheap by market standards. My reloads are costing me about $10 per 50 and they will match, if not exceed, any factory load. Take up reloading as soon as possible, you won't regret it!

Get on Underwoods email list. They often have Free Shipping for orders of $200 or more. Great ammo.! Kevin's good people too.

Yeah, once you start reloading, you'll never look back.

Might as well sign up at Starline brass for 10MM availability emails. Buy 1000 emptys. Large pistol primers, longshot powder or AA #5, Nosler 135 Grain, 1600 FPS. Incredibably FUN to shoot. Not much recoil but man, you know it's fast.

Have fun!

Edit. I run !onewolf and KKM. Both are good. 6 inch. Glock barrels are .007 inch wider chambers than aftermarket.
So cases fired in Glock barrels will have to be resized full length when reloading to fit in your 6 inch.

This post just convinced me to go for a 10mm. Been thinking about adding a Glock 21sf to add to my .45 collection (that now consists of various 1911s and a Glock 30sf), and getting 10mm conversion for Glock 21sf gen 3 I now plan to pull trigger on. 10mm sounds like too much fun to pass up. I understand a lot more fun when developing your own loads but didn't realize the different options out there for factory ammo at somewhat reasonable prices. I'm sold.

was going to recommend Oceanbob's advise, but i see he's already posted.

You guys are great salesmen! I've got Glocks in 9mm, .40, and .45. I thought I was handled.

I also thought I didn't need to reload.

Alright, the shopping for 10mm's in 2015 starts now!

Maybe start reloading!

You'll be surprised how soft shooting it is with regular range/target ammo. I use double tap 200g when hunting and it has about double the kick

[Oceanbob]

Another advantage is a 10 MM Carbine conversion.

Thanks for the info, but it brings up another question for me.

As I don't know enough about reloading and resizing cases, since oceanbob mentioned the barrel tolerances and proper resizing, does that mean I have to look for specially resized ammo when using an aftermarket barrel if I purchase reloads, say at a range?

Not sure if I'm interpreting this correctly. Do you have to be more careful or specific when buying ammo to fire through the tighter aftermarket barrels?

The thought is to enjoy using both barrels and use commercially available ammo until I can learn the ropes on reloading. I've never used barrels other than factory ones.

[Oceanbob]

No, most reloads will have been resized full length anyway.

When you buy your carbide die set, add this

If you reload brass that's already been fired in a Glock barrel, that brass will have expanded .007 thousandths Fatter than the chamber in your LoneWolf 6 inch barrel. If you reload that piece of brass without resizing it full length, the reloaded round will go about halfway into your LoneWolf chamber and get stuck.

It's easy to remove. It will fit just fine in a Glock barrel...

Just remember to tumble the brass, resize full length before reloading. Easy-peasy.

I picked up my 20sf about a month ago and I love it. You have made a great choice.

The only problem I had with my G20 was that it would shoot waaaay high (4" at 10yds or so) ended up buying night sights for my G17 & swapped the old 17 sight onto the G20 & corrected the problem, now it shoots to POA. The rear sight that came from the factory on the G20 was too tall.

Everything Oceanbob said.

I run a Glockmeister 22lb ISMI spring on SS Guide Rod on my G20SF's (and my G21SF as well, for 45 Super).

http://www.glockmeister.com/Glockmeister-Stainless-Steel-Recoil-Spring-Assembly-for-G20_21-GLOCK-Models/productinfo/GMSSR20CS/

When I run very hot loads the lower front part of the slide can bang the receiver right in front of the front slide lug. This can cause mushrooming. The 22lb spring keeps the slide from banging under heavy recoil and yet it will cycle my lightest 40S&W loads just fine, so I just keep it in all the time.

Many guys have never seen this frame battering under even the heaviest of loads, so before you buy, shoot some hot UW and check your gun.

For the tall woods where real bear (not to be confused with CA Black Bears) or Moose might be a concern, a 200gr WFNGC traveling at 1200fps from your stock barrel, loads like Double Tap sells, will give you all the penetration you will need. The prospect of having to use one of those at handgun ranges is pretty terrifying though. I guess it is better than a stick.

If you end up buying Underwood, save the brass as it is Starline.

Now you need to decide if you're going with blue, green or red. I'm talking about reloading companies. The red comes in two shades. I'm partial to the one that makes this here.
