New 22BR and 90VLD's

Ya know I have to MUCH APOLOGIZE to you for suggesting that!!! Can't believe I even said that! and I haven't even had a drink yet today! Must be something in the water or ???@#&^*
Its sometimes hard to tell one by looking but you can sure tell one by the sounds they make....

I think that if I can get my hands on some N160, I may give it a shot to see how it works.

 

I will be shooting this one again in two weeks. Using left over ammo from Perry.

 

I am looking at running a test this week with RL17, just to see what kind of results I come up with. Other powders that I have considered is RL19, but there is a feeling that it may be a lil on the slow side.
Update, just looked at the current powder burn rate chart from Hodgdon, it looks like some other considerations would be N550, Norma 204, AA 4350 and Hybrid 100V. Another powder that I had considered in the beginning was IMR 4350.

 

when 17 came out,.. well sometime after is when i tried to get it, finally got a jug an never found a good use
Hope it will work in the .22 Br for you.. i'd like to use it up to.. lol's thought 17 to be slower then varget for the heavey bullets ?... have you experimented with 748 looks faster varget ?

was gona pull that barrel again ... i'll wait to here about 17...

Enjoy

 

Rich,

Went out this morning and shot five rounds with the RL17, just to see where the pressure point was. Looks like it is 33 grains in my rifle.

Will probably shoot a few groups at 600 tomorrow.

 

I continully hear about rl17 not being as temp stable as varget etc. Wonder what the temp range is that people have had those issues?

Let us know how it works. Got a large jug I would like to use. Just wondering if load developed this time of the year would hold in the temp swings of our area for the same time. Allways wondered if the people having issues developed loads in the early spring or winter and shot them in the heat of the day in summer etc...

 

Ken,

Powders that a lot of folks claim to be temp sensitive, I have to wonder if they develop the working load in cooler temps and try to use it in the heat. You can indeed run into issues even with Varget. I have personally experienced this myself.
Do some powders have a greater affected reaction to temp changes, I believe so. The way I see it, develop a load in the temp range that you plan on shooting that load in.
In the same token, I feel that certain powders work better in some cases better than others. Some powders like tight neck tension and others like light tension. I have had good results in the past with RL17. Just being curious if it like the 22BR with the 90's. When doing research for this round combo, Quickloads brought up RL17 as the number one choice, H4350 was second choice. I have a good working load with H4350, but my curious nature wants to know if indeed RL17 will work in the case.

 

Well did a test at 600, all groups were under 1/2 moa but one group will deserve a try at 1000 yards. It was 32.5 grains of RL17 with the Berger 90VLD. I will probably not try the load till Monday, unless weather changes those plans.

 

Wow nice job Froggie...

gee i wonder if 32.0 would be a start load for the 70, 75, an 80's i've been trying... ?

 

Rich,

That will depend on the chamber. But what would do is to load some up in half grain increments starting low and try to find that pressure point. Your working load is going to be with a .8 grains below the pressure point. What I can also say is that my experience has shown that RL17 seems to like heavy bullets.

 

thanks...
my 8tw... did fair with the little i tested 80gr #9390

new hope Ha Ha !

thanks

 

In my 22BRs, the 80's did well with N550, but better with N150. Maybe N550 would be just right for 90's?????? but sounds like you are doing very well with your testing of Re17 also. Will keep waiting for updates and Thanks

 

Thanks dude, I will report back what my findings are after I shoot it at 1K.

 

Did another test of the RL17 at 600 yards today. The All Guard team member was watching the trace. He said it would rise to the top of the 7 ring at it's highest point. That was all of the elevation in the arc of flight for the bullet.

Below is the group.

 

Looks like a very nice vertical spread for sure. Are you jumping or jamming?

 

Jamming, the seating measurement is base to ogive 2.053, which is ten in with my chamber.

 

I counted 8 on the pic...very nice ones. Wondering what I would try next....maybe play with the seating depth a little more. What are your thoughts to try next?

 

I was using older brass that had been shot in another rifle. Been using this brass for testing. Have the bullet ten in and check neck tension. I am running around 2 thou tension, I am sure that it is soft seating to where it wants to be. This is my usual routine. Most times just a thou of tension, but never more than 2.
Are you turning the necks? I do, and size the wit a 246 bushing and the run the necks over a K&M expander.
