Generally speaking the less mass in front of the base of the bullet when it leaves the barrel gives you better accuracy. Truncated cones generally shoot more accurately at distance than round nose due to less mass in front of the base. JHP bullets have all the mass at the rear of the bullet and that helps it stabilize better before it leaves the barrel. When I was loading 50 yard ammo for Bianchi Shooters we tried all the bullets. Our best accuracy was from 115jhp at around 1150-1180 with a medium speed powder. You could get more accurate loads with slower powder but it did not work well with the time limits at Bianchi due to recoil. I worked up a practice load in 9mm using a 122 coated lead TC sized .357 and titegoup. 3inches or less with mixed rollsized brass all day long at 50 yaards. The cool part was my match load of Zero 115jhp VV340 FED match primer shot to the same POA POI with the only adjustment was two clicks windage at 50 yards, to account for the coated oversize bullet. If you need any accuracy JHP is usually the best, followed by coated lead ( I like .002 over bore size) then Jacketed round nose. The thin jacketed bullets and plated bullets usually don't shoot well at long distance.

I would put the mags back to factory, Oil the crap out of the gun, and shoot it. Get a baseline. If the gun runs on factory mags then you know it is the grams set up. Only change one variable at a time does work pretty well. Good luck!

I have been told that they update the site early in the morning with what they have and then when it is gone it is gone. I have not checked because I gave up LOL.

To Dave-T. Correct. There is some gas but not enough to work the comp the way an major caliber open gun does.

I use the 2040 size from greenproducts.com. They grind corn cobs up for all applications. When I was loading professionally I loaded a lot of JHP and used the 2040 size. This would not pack up in the hollowpoints and makes life grand. The last thing you want is a piece falling out of the cavity and jamming up your gun on the line. Been there, done that. It sucks.

I recently tried to use the moon saver on some moons I was given in a deal. If one finger of the moon is bent you can salvage it. If the moon clip is twisted in any fashion it will not go back to usable condition. I spent over an hour working on them and threw them all away. These were for starline 38 special/short colt. Life is too damn short. Just buy some more moons and smile instead of being upset when they fail you at the match....... DougC

These guns have been built for over 40 plus years. It is not a big deal. The common set up (which I have) is a 5 inch slide 1911 in 9x19 with a bushing barrel with a 2-3 port comp and slide lightened. I originally used a CMORE seredipity two side mount and switched to a single side CMORE mount. Forget about making the comp work. Common loads are 100PF. My load was 3.8 gr W231 with a 115 bullet. Good luck with your project! DougC

If the gun is has a Nitride finish I would recommend you polish the chamber. I have seen people that have had chambering/extracting issues improve after polishing the chamber...... Good luck!

Hey Steven, My pleasure. Both my parents and my son rocks a walker so I know my way around them. Happy to squad with you anytime! Shout out to Dean as well. I miss my Iowa homies! Revo shooters are the best. Steven, if you haven't had it done yet, I would have a smith run a reamer in all your chambers. The factory chambers are tight and extraction works much better after they are given a little attention. There are probably a dozen topics about it buried around here somewhere. Good luck to those shooting the Western States Revo match tomorrow! 290 rounds in one day!

Biggest issues loading 160s is that if you don't seat the bullet straight it will bulge and then it won't gauge or chamber. You have to take more time and make sure the bullet is straight when seating. The only way I salvaged them was to run them through a LFCD and then they would chamber. They are super soft though for sure! DougC

Maps, you might get a quicker reply from Stuart or other staff by emailing them at info@czcustom.com if you have not. Their phone number is (480) 969-1311. I know they have been pretty busy this time of the year.......

Smith refused to repair my 625 (center pin hole on recoil shield got hogged out). They wanted to sell me a new frame. I told them not to touch it and I had them send the gun to a Smith. He welded the hole and recut it. Tada. Back to 100%. Smiths like Joe at Mojo will get my work as long as he wants to work. Smith is not like it used to be..... DougC

I would also think about belling the case a bit more so your bullet can center up easier. I would try adjusting that and see if it helps. DougC

That bullet style is one of the most accurate Bullets in 9mm (non hollow point). I get mine from twoalphaBullets.com sized .357 and load away.

Good stuff guys! Got it last night. Took less than five minutes. Thanks again Stuart!

I recently purchased a czc ghost hammer for my SP01 firing pin safety model. After installing it I can only push the thumb safety up at half cock and not at full cock. I, after losing the little @$#& parts a couple times, put the factory hammer back in. No problem. I reinstalled the new hammer again. Same issue. Yes, I emailed CZCustom. I assumed I bought the wrong hammer for this firing pin safety cz-75 model. Thanks for any info. Doug

Thanks Stuart!

Hammer and sear not changed, and just SPO1. Not the Shadow

I have a SPO1 with a CZ Custom target rear fixed sight. Has anyone done the math and know what size front sight is needed for 115\124 and 147 Bullets at 25 yds for POA/POI. The 6 o’clock hold on the sights won’t cut it when every other gun I have can be regulated to that. after a bunch of research I decided I didn’t want to go the adjustable route. I have taken preliminary measurements from targets shot at 25 yds and “think” I have the right front sight heights. I would like to confirm with others before I buy more front sights. it appears I need a .225 height for 147. .215 for 115\124. Can anyone confirm? Thanks for any assistance.

First off I wanna thank everybody for putting the knowledge on this sub forum. I bought an SP01 and went through it and did all the mods and it is quite simply amazing. I have the 11 pound hammer spring in the gun, trued up the hammer hooks on the hammer. I am just over 6lb DA and around 3 1/2 SA. I still have a small hitch at the break of SA when I am shooting groups with it. My question is if I should work on the sear and what is suggested. Thanks in advance

John at Two Alpha Bullets can hook you up. I have been using his 122tc Bullets sized .357 for Bianchi 50yard loads for years. 2-3 inches @ 50 yards and same Poa/Poi as my match jhp load except 2 clicks windage at 50. I have the smaller Bullets sized .357 and get better accuracy.

I would not use a 9mm fcd with a .358 bullet. The die will stage down the bullet and accuracy will suffer. A standard crimp die turned down will work if you don’t have a 357 fcd DougC

You could just have your chamber reamed so you can load longer. You should be fine but better to be safe.

In the Revo you need a real big crimp so your last couple bullets in the cylinder don’t jump. A roll crimp is best but you can do about the same thing with a taper crimp too.

In conventional pistol bullets the jacket hollowpoint is considered most accurate. If you look at a cross-section of the bullet the heaviest part of the bullet is in the rear and that is the last part that is stabilized as it leaves the barrel. Other bullet styles lend them selves to be in accurate. A 122 truncated cone bullet is very accurate due to a very short pointed bullet front and the rear of the bullet is constructed like a hollow point with all the weight at the back . There were tests back in the twenties that showed the 120ish grain bullet had great accuracy in 9mm with tc style bullet. Quick and dirty take aways are that bigger diameter bullets are more accurate due to engaging the rifling better. When I worked up 95 grain loads in 9mm for steel challenge I had sub 1inch groups at 35 yds with 95 jhps. I had 4inch groups, if you call them groups, with 95 grain fmj. This demonstrates what a difference having the weight at the rear of the bullet to stabilize it will do for accuracy. Good Luck, DougC
