A17 ammo any good?



Log in to see fewer ads
I see where CDNN still has the A17 ammo for a decent price, and an even lower price if you buy it in a package with a Bushnell Rimfire Optics scope (3.5-10x, 40mm AO, trhee elevation turrets included). I've got that scope on a marlin 22 and I like it, was thinking about grabbing one of the scope/ammo packages for my savage 17HMR.

Is the ammo any good?

My CZs seem to shoot it well also does fine in my Ruger and Marlin so I would say yes.

My 93R17BTVS shoots it as good as the best I've tried and it's my go-to hunting ammo for foxes.

It is just a touch faster and flatter shooting than standard Hornady 17 hmr. There is a shift in POI on the target but group size is basically the same. I donít notice the difference while hunting. Should try it on a windy day and compare.

Ran across a clearance deal where it was 16 cents per round and run it almost exclusively now. In semi autos, bolts, revolvers, break actions. When the semi auto strts to gunk up, the A17 has enough umph to keep the bolt cycling properly where the standard 17 hmr doesnít. Just clean and lube the action, then both ammos work again.

Results depend on the batch, some do better than others.
I had decent results at 200 yards off the bench

It shoots good in my two HMRs (Anschutz and Sako), but not significantly better than other versions of 17HMR. Took 3 different ammos with me prairie dog shooting and noted no difference. The CCI TNT shoots slightly and consistently better at the range, but no real difference in the field.

I agree with others, good stuff. Just as accurate in my HMR. Never put any over the chrono, but all online reviews clock it 100-150 FPS faster.

I shoot it in my NEF/H&R heavy barrel gun and it performs really well, even with the crap trigger. As good as any other.

It shoots great in my 452 Varmint. One thing I noticed with the A17 in a couple places it cost more per round if you buy the 200 round box as opposed to 50 round boxes.

Always shot good for me. It’s a little hotter than some ammo, so not recommended in some guns.

For my 455 with lilja barrel, it only outshot the Winchester. Maybe it was lot luck, but all the others were consistently a bit better. Same for my friends Marlin.

CCI A17 - 17 HMR Ammo

I did some testing of a 200 round box of A17 in a couple of different CZ's - a 453 Varmint & a 455 Varmint both with 20.5" barrels. I had similar results with a Sako Quad Range & Steyr Zephyr II but do not have the chronograph results handy from those range sessions.

Group 3 # of Shots: 50 CCI A17 Varmint 17 gr rated @2650
Min 2554 Max 2904 Lot - ?
Avg 2774 Std Dev 88 ES 350


Group 3 # of Shots 50 CCI A17 - 17 Gr rated @ 2650
Min 2498 Max 2888 Lot - ? (Last 50 of 200 Round Box)
Avg 2756 Std Dev 87.9 ES 380

I did not keep track of any lot #'s but I was not impressed with the (5) shot groups I received at 50 yards with any of this ammo in any of the four different rifles I used for the testing. I did buy a second box of 200 rounds of CCI
A17 and had similar ES in the 35-400 fps range.

My best results were with CCI 17 gr TNT ammo with ES around 75 fps or the CCI 20 gr JSP with ES around the 160 range. Again 50 rounds @ 50 yards using 10 / 5 shot groups so that is what I currently use in my rifles. YMMV . . .

My savage B17 doesn’t like A17’s. It groups over 2” at 100 yards where cci game points or fmj’s shoot closer to 1” but my rifle might just prefer heavier bullets.

I am just stepping into the 17HMR pool so to speak. Played with the 17WSM and center fire 17’s to like them.

I see some crazy ES on post above. That is either primer(ammo) or ignition(firing pin) from my experience with rimfires in the past.

I have only tried a few of the ammos. Groups shrank with my ISSC rifle using A17. Still playing with it some. I may try some 20 grain ammo as time allows.

I shop around, the 200 round packs I have bought were at least a buck per 50 cheaper than 50 round only boxes.

Seeing as CCI and Winchester are the only two manufacturers of 17hmr cartridges
and they still use a manually filled punch plate to measure
and drop in the primer, my guess is major variations in primer amount.
It's not competition quality ammo. Hunting and plinking, where precision isn't critical.
