135 gr load data

[woodsplitter67]

Good afternoon to all. Thanks to all that reply. I have 2 powders on hand N-320 and autocomp I have 124 and 135 gr RMR truncated fmj. In my reloading manual there is nothing listed higher for me to average out to figure out a starting load. Does anyone have load data for a starting point. I'm not shooting matches or anything. Just putting together some rounds that we want to try out in our pew pews target shooting steel and paper.

Start with 147 grain load data and work up

3.4g n320

1.13

135TC Blue bullets 

right around 129-130PF out of a 4.75” barrel

Thanks for the reply.. As I stated above there is no load data either in my reloading book or on the manufacturer load data site that go to 147, hence the problem

Both powders are slow burn so im assuming that 3.4g and will work for both.

N-320 is not considered a slow powder and you CANNOT use load data from one powder for a different powder.

Hornady listed some load data for RMR’s 135 FP.  VV has some data for a plated 135.  I’ve got a few of their 135’s but haven’t got around to loading them yet.  N320 works good in a 147 and I think it will be good in a 135.

135s are my favorite by far. Great accuracy with both Blues and Black Bullets. Nice recoil impulse. 
 

135 Blue Bullet TC

1.11” oal

3.6g N320

Thanks for the heads up. I could use a little clarification. I was under the impression that when looking at load data you need to compare "like". So in other words, when seeking missing load data for a 135 fmj I shouldn't be looking at load data for plated or othere bullet styles.

I've shoot over 20k of this same bullet.  I use to use N320 3.4gr, Aol was 1.10 ish.

Now I use sport pistol 3.6gr, Aol is 1.10ish  PF is 129

Why the switch of powders?

You can look at it, use it as a sanity check or guide, but don't take it as gospel or blindly copy it.

 

[Tunachaser]

You can also look at data for 140 gr..  Vihtavuori publishes data for 140 FMJ on there web site.

 

With N320, for example, 135 plated starting is 3.0 gr. while 140 FMJ is 2.9 gr.  Very close.

and max for 135 is 3.7 while 140 is 3.5.  Again very close.

 

FOR ME ONLY I would start at 2.9 gr and do a ladder to 3.4 gr and see what the chrono says. YMMV

 

THIS IS WHAT I WOULD DO...NOT A RECOMMENDATION simply what I would do.

.n-320 and autocomp are on the faster side.. Im not sure why I typed that..

I like-

135 Blue Bullet TC

1.11” oal

3.5 N320

132-134 PF

 

135 Blue Bullet TC

1.11” oal

3.4 Bullseye

132-134 PF

 

The N320 is much cleaner, the Bullseye is much cheaper.
