.17 Remington load question

[bobcat93]

Any one try hodgdon CFE 223 when reloading for the .17 Remington with a Hornady #1710 ..25 gr. h.p. bullet..
I've tried alot of powders and the most accurate load I've come up with was using IMR 8208 brx powder ..I'm getting 1 1/2" -1" 10 shot groups @100 yds. ..I'm using my cz527 ..Not bad ..I may try CFE blk 300, and H-335 powder next..
Would like to hear from others what powder performs best for them..Thanks
I've tried varget, reloader 7, reloader 10, some other hodgdon powders , and AA, IMR powders.. but so far the best was what I listed above..

Try 2015 and the old standby 4198

Varget works great in mine, sub half in with the 25 V Max.

When I had a 17 rem. I had good results with IMR 4198 ...IMR 4320...benchmark...RL-15
I settled on imr4198. It was a fussy caliber for me to find the ultimate load ...dang near
burned the barrel up just finding the load I wanted...LOL. I will say it was a lazer.
Average velocity 4165fps. with 25 grain v-max and .7 groups at 200 yards.

I believe I shot 24.8gr IMR 4895 with 25 gr Hornady HP and Remington 7 1/2 BR primers. Very accurate and fast in Remington 700 BDL sporter

 

[xswanted]

I tried it. Don't recall the load but it didn't shoot very well.

Great velocity with 25 grainers but poor accuracy.

8208 is now my go to powder for the 17

 

[Schism]

I'm getting 1 1/2" -1

I'm using my cz527

I've tried varget, reloader 7, reloader 10, some other hodgdon powders , and AA, IMR powders.. but so far the best was what I listed above..

The information above has me wondering if something is awry with the rifle or setup. I've never seen a CZ527 that wouldn't shoot under an inch with several different powders instead of one that struggles to find a powder that will shoot sub MOA at 100. Can you give us a little more info about the rifle? Round count, stock, scope, etc.

To answer you question, I have a buddy who uses CFE223 in his CZ527 in 17 Rem with great success. I settled in Varget in mine an shave been very happy with sub MOA accuracy.

It has been a long time but I did try CFE223 and it was OK...but my go to load was Varget over a 25gr Berger because it grouped better and had a velocity edge. If you have that poor grouping, I suggest borescoping the barrel to see how fouled it is. A VERY thorough cleaning may be your solution. My Rem700 ADL shot outstanding groups (even with Rem factory loads) but seemed to degrade after 150 rds. I have heard that some rifles accuracy craps out with much less rounds than that. This gun is a late '90's era.

To be honest I think I received a lemon 527 the trigger is like dragging an anchor, it will not eject spent cases with out a little click of my finger, ..I just cleaned the heck out of the barrel with Montana extreme 50 BMG it's spotless..( no access to bore scope)..I just ordered a BC stock for it..I did pillar bed the factory walnut stock and it shot much better..
I have a leapold vxlll mounted with warn rings..It's all good optically..I think the problem lays in the action ..I'll see how it shoots in this new stock ..And if I can't get it going ..It's going back the the mother ship

I have been shooting Noler brass..I will try REM brass and see if it eject ..Maybe the rim thickness is different..I just thought about that ..So I haven't measured anything

21.5-22.5g if H322-2015, 7 1/2, 25g touch the lands, magic at 3850...large powder charges are horrible...this brings things down to Earth...tiny groups...tiny...long shot strings......

 

[bobcat93]

I will try it out ..I have plenty of H-322.. I did load some up with that powder before and If I remember correctly I wasn't impressed with that powder..
I did load some up tonight with H-335
I used Remington brass
Remington 7 1/2 br primer
Hornady 25gr. HP # 1710 bullet
H-335 powder
20.0 gr.
20.5 gr.
21.0 gr.
And 21.2 gr.
COL was .010 off of touching the rifling.
I received my new bell and Carlson stock for the CZ 527 varmint
I can't believe how nice the fit is..The action needed a little push to set it into the inletting so did the bottom metal. I used a fat wrench and snugged up the action screws to 50 in/ lb.
The barrel is nicely free floated and perfectly centered in the barrel channel..
What a great stock..I'm very happy..And very impressed with the inletting on this stock..
Two thumbs up for Bell and Carlson..

 

[bobcat93]

I thought I would share a pic of my CV527 in its new stock..I know how you guys like pictures..
There are many like it , but this one is mine.


Also here is the group I shot in the factory stock after bedding..It was a 7/8" -10 shot group@ 100 yds. I guess that is respectable for a factory barrel..If I could get it to 1/2" I would be happy..

What sort of case prep do you do on your cases? I weigh my cases and I debut the flash holes ... made a big difference in my group sizes I always use Rem 7 1/2 primers. I have the best luck in my 17 Rem with H4895

I did no case prep, supposedly nosler brass is wieght sorted, and flash holes debured.i do full length size new brass. I have tried H4895 with out much luck..
I guess I posted pics of the target to get feed back from others.
I'm not the best shot and don't know why my group is so vertical..Is it me, the wind, the rifle..
I have a lot to learn about the shooting characteristics of the .17 Remington..Granted it's a stock factory rifle.. others have posted how accurate the CZ527's are. Is this group on par. With the group's others shoot with there cz527', or the .17 Remington.,.Or do I just suck..Haha..
I would like to say some of my issue is most of my rifle triggers are set at 2-6 oz. Pull. And moving to a (what I call) a sloppy, factory trigger is effecting my group size.
Again this is only @100 yds but it is a 25 gr. .17 Cal..
Could use some pointers..
What type of groups should I expect from a factory chamber, in a factory barrel , shooting a .17 REM
Thanks

 

[pacificman]

I'm sure you already know this but sitting hear looking at your 10 shot groups I was thinking about allowing
your barrel to cool after 3 or 4 shots. I would shoot no more than 4 then let barrel cool completely. Also I was
surprised that h4198 worked so well in my rifle as it's a faster burning powder... After barrel burn out I used rl-15
with heavy bullet and regained accuracy. I remember using cci br4 primers...ya might try those too. I found the
17 rem. a challenge ...but was fun to work with as I learned a ton because of that cartridge.

It is on VERY rare occasion that I shoot more than a 4-5 shot group with a 17 Rem, 220 Swift, 22-250, or 243 that is a HUNTING rifle. Sporter weight barrels get hot quick and the shots after the first 3-4 sometimes don't tell you much other than the barrel is getting warm... (IMHO)the first 2-3 shots are the ones that count out of a fouled hunting rifle barrel. So I focus on them mostly.

One more suggestion and a comment and I'll shut up. You might want to take a closer look or rethink about sorting and prepping Lapua brass. It's good stuff, but every time I've sorted and prepped it I was very glad that I did.

The centerfire CZ's are generally pretty well liked and very easy to look at, but I've seen some that shoot lights out, a couple that shoot then quit shooting, and a couple that just NEVER shot worth a hoot. I've yet to actually see one of their rimfires that wasn't a good shooter. JME. FWIW. WD

If you shoot 5 shot groups instead of 10 shot groups you'll be close to the 1/2" mark.
Using wind flags will also help.

Thanks for the tips guys..I appreciate it..I will do 5 shot groups letting the barrel cool between groups and see what I come up with...
I just always thought you could see more in a 10 shot group then a 5 shot group..
Also after I shoot the loads I made up with the H-335 I will sort my cases and see if it makes any difference..
The .17 Remington is definitely a fun cartridge to load, and shoot..
I was thinking before this barrel is toast I may order a couple new barrels. I have been told that Lilja barrels are the way to go when it feeds to .17 Cal. and as for the .17 Remington have the barrels chambered with no lead. Perhaps I will go with a tight neck .193"

Any thoughts or suggestions
