Well, after starting to build a CZ 527 17 AH,,,I shot it friday..Wowsers! You 17 guys HAVE been having FUN! The barrel I used was match stainless/24", and I could NOT stop shooting until the 75 rounds loaded were GONE!
One thing I noticed,,the picture of the 200 yd target was funny to see as the 'shock wave?' completely altered the target for about a half second after the shot,,,,neat effect!
The only problem I have now,,after shooting the rifle (had been completed the nite before) a friend who has several 17 rifles offered me two new in box CZ 527s for it. Now I HAVE to build another quickly! alan in ga.

You better had get busy. Sounds like a fair trade. Was your .17AH a repeater, did it feed?

We loaded some 20 Vmax's for fireforming and loaded 'em way out onto the lands since the 4198SC pretty much filled the case. Cases looked like some had 2 rings from trip thru the die. Used a body form die and some just the full length size (boy, that sizing wax is great stuff!). Although the cases looked funny, NONE were lost in fireforming with all perfectly filled out and no cracked cases. Some of cases were once fired, some had been loaded as 22 hornets for 2 or 3 loads previous! New ower of rifle(yes, I traded after having just completed the rifle nite before) has already loaded up 650 rounds to be used on gopher trip in last week of May in Montana.
I'll call him and see if he's tried the cases thru the clip/feeding. alan in ga.

I have been reading and watching the posts here. I am wondering what is going to be the best powder to use in my 17AH. It has a 24" Shilen tube and I am going to use only 20 VMAX's. I would like to use an extreme powder so I would not have to worry about temp. messing with the load. What about H4227 can I get enough powder in the case to reach a max load? Or should I break away from the extreme stuff and use Lil-Gun powder. I am a die hard user of Hodgdon powders, any suggestions? Would like velocity as long as it shoots well.
Thanks, Your friend, Chucker.

I was using V V N-133, but it was too slow for the 20 gr V-Max bullets, moly coated. I switched over to AA-1680 and at about 12 gr, I get 3700 fps out of a 22" Contender barrel from Bullberry. There are no excessive pressure signs. I also use the Rem 7-1/2 primers because of the stronger primer cups. Good Hunting from... Varmint Al

One of the only suitable powders I haven't tried in the 17 AH is H4227.......but I do believe it will get you where you want to go. Once I stumbed upon N-120 it quickly became my favorite for 20 gr. bullets. It seems to be pretty consistent in varying temps too, and meters well enough to charge cases right from the measure. Kernel wise, it is exactly the same size as H4227. Very clean stuff. But as I stated, H4227 may be every bit as good.........There, how's that for typing a bunch of words without actually helping you!!! For what it's worth, I didn't like Lil'Gun in the 17 AH. It's very fast in this case and fill ratio is only about 60% or so. Another powder that works well is el cheapo Accurate 2200. That stuff IS temp sensitive, but for summertime PD shooting offers some good economy at $47 for 8 lbs., or about 4000 shots!! Dan C

Hey Alan, I like H4198 with 25 grain bullets, but loading a bunch of them is a drag as it doesn't meter very good! Dan C

I don't have a 17 AH but I have heard that WW680 is supposed to be a good powder for it. Similar to AA1680 and the old Win680. It is available from most of the surplus powder distributers for around $5 per lb.

I have used IMR4227 and it worked good. Velocity was good and accuracy was good. I was using it while fireforming so I am not sure how full you could get the case, but I was able to get 3200 fps out of a 10" contender barrel while fireforming with 20 grain bullets. Accuracy of the fireforming load was great. I lost one case out of 50 to a split neck with the 3200 fps load.

.. as I get about 3800 fps using 12.5 gr both to fireform and afterwards. So far I haven't lost a case! I'm sure that will change. I also use WSR primers. You need to know about pressure signs long before you would even notice anything unusual happenning to Rem 7.5 primers, and there isn't enough powder to warrant the extra fire. My take on the VMax bullets has not been good. Maybe I got two bad lots, or maybe I'm not seating them deep enough into the lands. The shoot patterns in my Cooper M38 old style Classic (20 inch barrel). Starke 20's are both accurate and have a good terminal result (200 yard, 20 oz Pepsi bottle splits in two). Berger 20 HP's are also accurate, but terminal effect is a small exit hole in the bottle. Virginia groundhogs don't survive the Starke's, run off with the Bergers if the placement isn't just right. I have not tried Berger MEF 20's, which I have seen praised as the most accurate 20 gr pill on GGVG. I haven't tried N120. Thanks Dan C. Will get some. My experience with the VV powders (133 and 135)is that they are quite clean. Our local shop (Greentop in Ashland, VA) has stopped carrying the AA line of powders. Bought a bunch they had on sale as they dropped it in favor of the RamShot stuff. Alex

V n-120 is the best I have used 3715fps out of 20 inch pipe and never shoots above .500

Is H335 temperature sensitive? I tried some loads today using H335 (19.7gr with Hornady 25gr HP) in my 17 Mach IV and the results look promising.

I never used H335, but according to Todd Kindler, the H322 is better for summer heat. I believe that he indicated that the H335 was a little temp sensitive. The H322 is in the extreme line as well as the H4198. I have used H322, H4198 and n133 in the Mach IV.

Using Hornady 25gr HP and H322. Any suggestions where to start with H322? The Hodgdon reloading manual does'nt even list H322 for the 17 Mach IV.

17.2 gr. H-322 with a 25 gr. Starke gives me great accuracy and no pressure signs at all. Visit my homepage at....

I will have to check my notes and report back. I used the Sensational Seventeens manual as a baseline - I usually don't go as hot as Todd says is HOT. I only used 22 grain Bergers, 20 grain V-maxes and 20 grain starkes in that barrel - it was a 20" barrel. I won't be able to tell you much about 25 grain bullets, but there are a lot of Mach IV shooters on the board that can point you in the right direction.

Yes it is temp. sensitive. I have been caught with this problem. I have replaced H335 with H322 in my MachIV just for this reason. H322 is an extreme powder and it meters great. It is not temp. sensitve and you get great velocity with adequate loading densitys. Use it you will be surprized at the result.

Chucker, sorry to burst your bubble but in the interest of safety H322 is even more temp sensitive than H335 particularly with warmer temps, ie more pressure. In my MkIV I've seen 200fps with 15 deg. increase. If your warm to begin with watch out. Thats one big reason a lot of us long time BR guys moved to the Vit. powders.

I have been using the Extreme version of H322 and it has been real predictable so far. Cause I am driving the 20gr. VMAX fairly stiffly and I can't afford a temp variation. Thanks, I will keep may safety glasses on and my head on strait.
Your friend, Chucker.

One other issue to be aware of, 322 can vary greatly from lot to lot & it drives everybody nuts but the temp sensitivity plus the lot variable is a lot to think about. Hope this helps.
