Not that I'm aware of. 220 doesn't leave a whole lotta room for powder if you stick to saami max oal.

You could always swage down a 41 cal :)

I haven't checked for a while, but Double Tap once did sell the 230 gr WFNGC  bullet in component form that, I believe, weighed closer to 220 gr.

snscasting .com has coated and uncoated 220gr. in quantity and sample packs

I think some of the loaders used these Rim Rocks in the past.  I bought 1000 of them and they lead both the Glock and KKM barrels badly.  They are .401 and probably need to be .402.  They also tumble on me creating very large groups at 25yds.  I bought some tumble lube to see if it would fix the problem and have not taken the time to load them up yet.  Its a good looking bullet that I think has a 15 bin that should be good to go.  I think they also make a harder bullet as well.

I swaged down some .410 215's, up to 1,140 with #9. Might hit 1,200.

Your best bet for a consistent supply is to start casting.  This has other advantages beyond controlling supply.  You also control final diameter and alloy, allowing much better control over internal and terminal performance.

Accurate offers several 220 grain molds.  The 40-220P look interesting to me and looks like it might be a good option where case capacity is a concern.  It's length is the same as the Hornady 200 grain XTP.

That is interesting. I can get the 200 XTP moving @ 1250. I wonder if I can get the 220 going at about the same speed. Would be a great hog round.

Underwood pushes a 220 hard cast to 1200 fps.  I would consider that a hard ceiling.  Our pull-down suggests this load was 8.0 grains of Hodgdon Longshot (thanks Shadow). I would reduce 15% to 6.8 grains and work up.

Keep in mind a properly fit lead bullet seals the bore better than a jacketed bullet.  Better seal = more pressure = more velocity.  This is generally offset in reloading data by the fact that a hard cast lead bullet will be shorter than a dimensionally identical jacketed bullet.  Loaded to the same COAL, that means more initial free volume and a lower initial pressure from the same powder charge.

Well said SQLBullet, even the pull-down from DT loads 6.2grains under a 200 grain cast for 40S&W.  See link for study.

I would work it up very slowly.

I still have a box of old Redline 220 cast boolits that were sized to .401. Anyone ever use these?

The Redlines leaded bad in my 610. Accuracy was so-so. When I shot them in my S&W 1006 using a fitted Bar-Sto tube, I started getting feeding problems after the first mag or so. But at the time, I wrote it off as likely being due to COAL issues and my own inexperience with loading the cast stuff for use in an autoloader, not to mention it was a tight-chambered Bar-Sto. The B-S tube ran fine with factory 10mm ammo and my jacketed-bullets reloads.

I'd like to try SNS's coated 220gn, but are those sized to .401 or .402?

Anybody loaded these coated 220s? What results at the range?

The coating will add to a better sealing dia and prevent lead contact with the bore... Some are having good results using the shake-n-bake method of powder poly paint applications.

I size my cast bullets to 0.4015", this fits inside without shaving or squeezing down.

Shadow: do you think it would be worth "white gassing" my remaining Redline 220s to get rid of the red mold lube, and then dry powder coating them, as you mentioned, to eliminate leading problems?

I know I can't do anything about the sizing (.401), but they're sitting here in a box unused, looking like a waste of $$$ at this point. If I didn't already have them, I'd go ahead and buy 1K of SNS's 220gn coated bullets.

Yes, you could clean them of lube first, then maybe rinse with acetone, but the price of the cleaners are likely more that getting some new already powder coated bullets.  LOL  Some have used the acetone or MEK as a wet transfer of the powdered paint method trying to eliminate excess.  The pul measured amounts for the amount of bullets and shake till they get good and sticky then spread out on wire to dry separately, then bake to cure.

It would be good project and you'd have powder left to do others.

I think you're right.

Thinking thru it a bit more, ... when the cost of the cleaning agents, along with the  time and hassle involved, are factored in, it adds more steps to the process. It might just be simpler to buy the costed SNS 220-grainers, and get right to loading.

You can boil them in water. The wax will float to the surface after it melts off.

Shadow, where did you get a .4105 sizing die? All I am seeing from Lyman, RCBS and Lee are .401. Keep seeing the suggestion of sizing to .402 if shooting in a Glock OEM barrel.

BillinOregon, my die is not 0.4105"   My die is for the STAR sizer and it was ordered at 0.4015".  It is working well  for my guns even the Glocks factory BBL.

Hey guys, checking in again with a 220gn HC question ...

Looking for some expert suggestions using AA-7 powder, as that's what I'm heavily stocked up on.

Last week I received a 500-rd box of SNS's powder-costed HC boolits.

Looking at my old loads notes from back when I was experimenting with some crappy way-too-soft Redline 220s, I worked up from 8.5 to 9.2 of AA-7, but the leading in my G20's LWD (stock-length) tube started causing chambering issues, in addition to being a PITA to clean up, so I basically put those boolits away, and went back to playing with 180gn jacketed loads.

Now I've got my G40 to play with, using the stock barrel with these SNS coated 220 pills. I'm looking to develop a nice, hot woods-busting load. This would be using new Starline brass and CCI 350 mag primers.

Anyone developed a "Heavy & Hard" 220gn load with AA-7? Thanks!   8)

I've loaded SNS' 220s w/ #9, and the best velocity (G20.4 w/ AF 5.2") I could achieve before hitting my stopping point was 1,050. I did get another 50fps out of 800X, and am still working with N350.

My own data suggests that #7 is best relegated to 180s and lighter (absolutely shines with 165s), and that 220s are a bit too big for the 10's case - better #s can be achieved with a 200 WFN.

If you end up testing #7 & 220s please post your results!
