The OAL was chosen so not to touch the lands .
Yep, what’s the OAL?
I generally run 9MM RN at 1.130 to 1.135 OAL
I may need to try 115gr coated. I've only load 124gr Hi Tek rounds and they have been a total bane to my shooting/loading success. I'd be a pleased puppy to seat my rounds to 1.125" maybe a bit less and maybe just slightly touch the lands.Sorry, should have noted that OAL is 1.128.
For the CZ I usually try for 1.100 average. It is a WIN case. I guess the 0.03 makes the difference.
not his picIt appears by your pic, that you need to choose again........

In the pistol calibers I reload, I always do a plunk test to find the max COL the barrel will allow. Depending on the bullet profile, and barrel, it’s sometimes less than the specified max for the caliber. I presume you referring to the SAAMI max. CZs often plunk less than max.If the OAL of the loaded round is within the specified max for the caliber, you should have no functional problems, though accuracy is usually better when the clearance between the bullet body and origin of the rifling is minimized.
I would find Jam and digress.
I think that is a bit long for 115gr bullets...especially RMR FMJ in a CZ....some RMR 115 bullets
...that OAL is 1.128.

A bit confused here.I got this result by spinning the round in the barrel. Plunked great but made this scraping line just above the case.
Sorry that I did not translate that well. By finding jam I am referring to the point to which the bullet contacts the lands of the rifling.Huh?
I think you're right. OP was trying to find where he hit the lands. I was pretty excited to see what I thought was coated lead with nearly flawless coating.Just to be clear, RMR’s 115 is a FMJ, I believe the one in the picture has been “sharpied”.

That said...I DO need to buy some RMR seeds.
9mm- Yes they do plunk great in the CZ barrel. Maybe I put too much downward pressure on the round when I spin it, causing the marks.
Also, what OAL do you use for the RMR 115? BTW my last buy at RMR I received some bullets that were 5.70 long rather than the previous ones that were 5.555. Both were 355.5 wide at base.
Plan to contact Jake.
