Moving to coated bullets - need suggestions

The only problem i see is the OAL you are looking for. The new 124 grain bullet from ACME that was redesigned for a longer OAL might get you there but i do not believe you will get that with any of the other of the makers. The  new ACME bullet was designed to address the short OAL in CZ's and other short chambered guns. You might want to get a sample order from each of the ones named above to find out which one works best for you.

 

Yeah, their old 124-grain round nose did not work out for me.  I ordered a 500-round pack from Acme to try out last summer, and in my guns (Walther P99 and P99c), I could not get rounds loaded any longer than 1.037" to pass the plunk test.  A few weeks ago, I put an ad on my local forum trying to get rid of the almost complete package at roughly $0.05/bullet, but no takers so far - I think I might have to call it a loss.  :(

 

If they've changed to a more short-throat friendly profile, I may give them another try at some point, but I did just buy a case of blues (125 TC), and they happily load at 1.12" for me, so maybe I"ll just stick with them.  Once bitten, twice shy and all that.

The problem with his 1.15 OAL is that his gun does not love 1.15 OAL.  His gun might do well with that bullet he uses at that OAL, but the gun couldn't care less.  Remember that OAL is the distance from the head stamp to the nose, and the nose never actually touches the pistol.  How far the nose is from the headstamp has no ballistic effect whatsoever.  What he needs to do is learn how to determine OAL for his CZ, then buy good bullets and load them to an OAL best suited for that pistol, and 1.15 won't be it for most bullets.

So the gun(s) have shot OAL’s from 1.09 to 1.15.  I seem to get the best accuracy from 1.15 albeit sooty cases.  At 1.09 I get clean cases but a wider spread.

 

l know how to plunk test a round, that is how I came to the 1.15 size - looking for the max size to see if accuracy is increased.

 

The reason I brought up size was for the exact information provided, input on people’s experiences.

 

Thanks everyone for the input!
