Superpipe9 Posted April 13, 2015 Share Posted April 13, 2015 What's the better bullet weight for the CZ 75 sp-01 shadow Link to comment Share on other sites More sharing options...
2MoreChains Posted April 13, 2015 Share Posted April 13, 2015 Some people have had problems with 147's hitting the rifling before the slide is fully in battery. It depends on the shape of the bullet. If it has a tall shoulder you may need to get your barrel throated. Or you can try and find a 147 bullet shape that fits your current barrel. Best advice is to buy some of each and give it a try. General rule of thumb, heavier bullet with fast burning powder results in a 'softer' recoil. Light bullets have more of a snappier recoil. Link to comment Share on other sites More sharing options...
Superpipe9 Posted April 13, 2015 Author Share Posted April 13, 2015 I am shooting 135 bayou bullets currently with titegroup making 135PF but am thinking of switching to 147's to see if the recoil is softer Link to comment Share on other sites More sharing options...

Bouboy02 Posted April 13, 2015 Share Posted April 13, 2015 I am using 147gr coated sns bullets with n320 at 1.138 oal. Real accurate and soft shooting in my shadow. Link to comment Share on other sites More sharing options...
cnote Posted April 13, 2015 Share Posted April 13, 2015 I am using 147gr coated sns bullets with n320 at 1.138 oal. Real accurate and soft shooting in my shadow. Drop and spin works fine at that OAL withe the Sns ? Link to comment Share on other sites More sharing options...
joeg Posted April 13, 2015 Share Posted April 13, 2015 i use 147gr with my TS. Love the round with this pistol but a friend of mine uses 124gr. They say is more accurate. I can shoot 1inch group with 147 as well as 124 so other than the recoil, both rounds are very accurate. Link to comment Share on other sites More sharing options...
corny Posted April 13, 2015 Share Posted April 13, 2015 I sent my SP01 barrel to: Beven Grams Grams Engineering 2435 Norse Ave. Costa Mesa, CA 92627 phone: 949-548-3745 fax: 949-548-8122 website: www.GramsEngineering.com email: teamge@gramsengineering.com He cut the throat and I can shoot whatever I want out of my CZ. Had it back in 7 days. Link to comment Share on other sites More sharing options...

inertia Posted April 14, 2015 Share Posted April 14, 2015 Keep in mind that some or many of the 147 shapes I have tried were at least as forgiving or more so than the 135s. I shot 135s for a full season and switched to 147 this year and they are actually easier to work with for length. I used BBI and Bayou 135 and tried some SNS. Now using BBI, Bayou, SNS, and a lot of extreme 147 with no issues. Link to comment Share on other sites More sharing options...
Nimitz Posted April 14, 2015 Share Posted April 14, 2015 (edited) SP01 Shadow; 147 Extreme RN loaded to 1.15 OAL, 25,000+ rds downrange without issue Edited April 14, 2015 by Nimitz Link to comment Share on other sites More sharing options...
accu9 Posted April 14, 2015 Share Posted April 14, 2015 I also found 147's to be far easier to load than 135's in respect to OAL. 147's are softer shooting-less powder to make power factor = less total ejecta = less recoil. Link to comment Share on other sites More sharing options...
Midas Posted April 15, 2015 Share Posted April 15, 2015 So I just back my Sp01 Shadow from Dave at CGW . I can load Zero 147 to about 1.150. I use 3.5 of N320 for a Power Factor of 134 Shoots pretty well. Also worked well in my p09 Jan Link to comment Share on other sites More sharing options...
valerko Posted April 15, 2015 Share Posted April 15, 2015 I shoot my own 135g Molly coated mostly as well as 147 extreme bullets. Almost no difference in recoil Link to comment Share on other sites More sharing options...
Superpipe9 Posted April 15, 2015 Author Share Posted April 15, 2015 I have always shot 135's and love them but am curious how much softer do the 147's feel. I also use titegroup so that doesn't help the recoil any Link to comment Share on other sites More sharing options...
valerko Posted April 16, 2015 Share Posted April 16, 2015 147 from extreme boolits and my 135 , don't really feel different. Link to comment Share on other sites More sharing options...
accu9 Posted April 16, 2015 Share Posted April 16, 2015 Recoil is subjective. Ask 5 people about a particular load shot through the same pistol on the same day and you will get 6 different answers-so to say. Let's take subjectivity out of the equation and get down to physics...more gunpowder = more recoil. That's all there is to it. At identical power factor, heavier bullets will ALWAYS have less recoil in a non-compensated pistol as they require less powder to achieve said PF.

Supranatural Posted April 16, 2015 Share Posted April 16, 2015 I use 147's in my tac sport and it feels like I'm shooting a 22. I'm a noob so I have to ask..it seems counter intuitive that a heavier bullet would have less recoil. I would think that a heavier bullet, requiring more force to get moving (faster burning powder as someone posted about in this thread), would create more ft lb of energy that would translate to more felt recoil...

It would if you were trying to get it going the same speed. The difference is you just have to get it going fast enough to make PF thats where the difference lies.

2MoreChains Posted April 17, 2015 Share Posted April 17, 2015 125 gr bullets need to be moving 1,000 fps to equal 125 PF. 147's only need 850 fps to equal 125 PF Link to comment Share on other sites More sharing options...
Gcarr Posted April 25, 2015 Share Posted April 25, 2015 I have shot a lot of 147 and switched back to 124... I really don't feel that much of a difference... 147 make gun feel a little slower to me. To me switching back and fourth is to much trouble with having to change the sights... Think I am just going stay with the 124.... Link to comment Share on other sites More sharing options...

Gcarr Posted April 25, 2015 Share Posted April 25, 2015 Very true on changing the recoil spring it does make a major difference.... Definitely need to tune the gun to the load your shooting. Link to comment Share on other sites More sharing options...
