d_striker Posted March 16, 2015 Share Posted March 16, 2015 Planning on picking up a Shadow Target. I just ordered a caliber conversion kit for the 650 and a couple thousand Xtreme 147's to try out. I plan on working up loads with e3 but was wondering what OAL works best with the Shadow. I've heard you can't load too long for them. Link to comment Share on other sites More sharing options...
Hi-Power Jack Posted March 16, 2015 Share Posted March 16, 2015 Plunk Test. Link to comment Share on other sites More sharing options...
Smitty79 Posted March 16, 2015 Share Posted March 16, 2015 You have to test. I load for my son and myself. 4 CZ 75 pattern, including 2 Shadows, between us. I've had bullets that I could load to SAAMI max and I've had bullets that I could barely make an inch. They are universally shorter than the other 9mms I load for. You have to check your barrel. I use the guidance here: http://www.czfirearms.us/index.php?topic=34225.0 Link to comment Share on other sites More sharing options...
inertia Posted March 16, 2015 Share Posted March 16, 2015 The xtreme 147 will be relatively forgiving in that gun compared to some other options. I go 1.13 but there is a little room left. Just do the test and back off a little. That bullet is not a problem for the CZs as some others are. Link to comment Share on other sites More sharing options...

sbo76 Posted March 16, 2015 Share Posted March 16, 2015 My shawdow liked 1.130 with rn bullets and 1.100 with jhp's. Link to comment Share on other sites More sharing options...
EngineerEli Posted March 16, 2015 Share Posted March 16, 2015 Do SP-01, or CZ owners for that matter, ever get their barrels reamed out to accept longer loaded ammo. Seems like it would make sense and could be done by a gunsmith pretty quickly. Heavy bullets with fast powders loaded to 1.10" and shorter makes me nervous...

CZ85Combat Posted March 16, 2015 Share Posted March 16, 2015 I have reamed all of mine + 0.050 Link to comment Share on other sites More sharing options...
BeerBaron Posted March 17, 2015 Share Posted March 17, 2015 My shadows all run just find up around 1.13 but shot tighter groups down around 1.090. This with 135gn rn frontiers cmj sized 356. So I guess I'm saying don't be afraid to test a few different lengths. Link to comment Share on other sites More sharing options...

Like you, I've found a little more accuracy going shorter in my Shadows.

Yes, some folks get the throat reamed to allow slightly longer OAL, but you can't go crazy, the next constraint you'll hit is the mag, how long overall length can be before bullet drags in the mag, so check that also.

thompsoncustom Posted March 17, 2015 Share Posted March 17, 2015 I run some 160gr bullets without a throat reamer but it's in the mail as we speak I would say your better off having it reamed or doing it yourself. Link to comment Share on other sites More sharing options...
razorfish Posted March 17, 2015 Share Posted March 17, 2015 Definitely interesting. What kind of accuracy improvement are we talking about? 1/2"? 1"? I didn't document the results of my testing but from memory I would guess my groups tightened up about 1/2". At the time I was shortening my loads and increasing my power factor to knock down steel (yeah, I know, one thing at a time). I ended up at 1.09 OAL and 133 PF. (Bayou 135gr bullet over 3.6 grains of VV N320 using a CCI SPP and mixed brass) I've always assumed the increased accuracy was due to the extra power of the round, but the shorter OAL may well of been a contributing factor (and possibly the only reason I saw better accuracy). If I had a range outside my back door I'd find out the answer. As it is I'm far too lazy break down the variables and find the answer In general, I hate reloading but love shooting... once I find a suitable load I'm done (until I run out of a particular component anyway). I'm currently working up a load for a 9mm Major open gun. I'm going on two months of procrastinating/testing. I wish guns came with the ideal load recipe printed on the barrel... That would save me a lot of aggravation Link to comment Share on other sites More sharing options...
rowdyb Posted March 17, 2015 Share Posted March 17, 2015 for round nose extremes in my cz i like 1.125 of an oal. for hp or others i go 1.110 Link to comment Share on other sites More sharing options...
hangin Posted March 22, 2015 Share Posted March 22, 2015 My loads with Xtreme bullets both shot in a SP01 and a 75B. Both work in factory 16 round mags, Mecgar 16 round mags, Mecgar 17 round mags, and SP01 18 round mags. Both pass the "plunk" test in both barrels. Neither have been reamed. 147 RN 1.145 oal federal 100 primer 3.2 GN Titegroup 130 PF 165 RN 1.150 oal Federal 100 primers 2.6 GN Titegroup 132 power factor Link to comment Share on other sites More sharing options...

Sorry if I was unclear I can get a little over 1.15 with the xtreme 147s in both of my shadows I just load little shorter to keep loads consistent in velocity across a few different bullets. This bullet in particular is much more forgiving of length than most of the others I use. Link to comment Share on other sites More sharing options...

I've heard you can't load too long for them. Unless you are willing to ream out your barrel, you will always be stuck with whatever you were dealt with. Personally, I like loading my bullets as long as my magazines can handle. My Chrono results and field testing have not shown any difference in velocity/accuracy with my previous loads. You can call up Manson Reamers and tell them what you are looking to do and they will send you the right reamer. I suggest getting the handle as well. Just remember to take it slow and only cut what you need. You can always take off more, you can't add any material back.

It's good to know that you and many others are able to use this bullet out to 1.15". Link to comment Share on other sites More sharing options...
accu9 Posted March 24, 2015 Share Posted March 24, 2015 Like others have mentioned he Xtreme 147gr RN is an incredibly forgiving profile for CZ's. My current load from my CZC Accushadow is: 147gr Xtreme RN 3.1gr E3 Winchester SPP 1.15 OAL 130 PF Soft, clean and super accurate. Link to comment Share on other sites More sharing options...
