.17hmr accuracy?
« on: December 18, 2005, 01:23:36 PM »
I have tried several different brands of ammo, Rem, Federal and Hornady. I have put about 80- 100 rounds through it. I have not seen the " sub MOA" groups that everyone talks about with these rifles. The Hornady was the best of the bunch with a approx. 1 1/2 group. I think someone mentioned before that these rifles require at least 150rds through them to realize the best accurac. Is that true or did I get a lemon? I have a BSA Sweet 17 scope(checked all mounts and screws).

remember these are H&R/NEFs you'll probably havta tweak it. i got lucky with a sub-MOA rifle out right. first clean the underside of the mount and holes, put loc-tite(blue) on the screws, make sure rings are tight to mount and snug to scope. Are they consistant groups? if so then a problem with a scope can be ruled out. I also have the Sweet .17 and its well sweet :). if everything scope wise checks out then (are you resting on the hinge? mine likes a bipod on the sling stud, but hinge is the usual best rest place) if thats fine then adjust the fore-end screw tightness(mark the orignal posistion to revert back to if needed).use one brand/type throught the whole process. did you take apart the gun and clean the hinge, latch area?

my apologies if this seems jumbled or incoherent.

That's true with most factory production rifles, unless it's got a custom barrel. You can plan on using upwards of 4-6 boxes of ammo before you get best accuracy, and what it shoots good now, may not be whatcha end up with. Don't be afraid to try different ammo as well as different lot numbers. I have 4 hmrs and they all shoot different ammo best, Hornady 20gr XTP and CCI Gamepoints also shoots good in one of em, but not all of em. Even though all 17hmr ammo is made in the same plant by CCI in Lewiston, ID, they don't shoot the same, so be flexible.

You can reduce some of that shooting by polishing the bore, see the Cleaning and Lapping sticky in the Centerfire forum.

The .17HMR is very susceptable to wind, be sure to try for your best groups on a calm day. Also be careful to position your head exactly the same for each shot as parallex can cause inaccuracies often thought to be the gun. It is difficult to keep a constant head position when you have to pull the gun from your shooting position to reload.

All of the Sweet 17 scopes have AOs cept for the 3-9x and I think it's set at 100yds, so parallax shouldn't be and issue with the AO adjusted properly. If wind is the issue, you'll see lateral stringing, depending on the velocity of the wind.

Have you tried the Speer bulleted ammo?  If I remember, it is the one that is supposed to be the least accurate in the 17's, but turned out to be the best in my 17 (the sub MOA type) :-)

Quick, do you know if they use the same powder and priming for the various brand names.  Maybe its my imagination, but I get better grouping from the Fed V-Shok than any other.

The only powder that I've read that the author "thought" they use is 5.4grs of Lil'gun, that was in Hornady ammo done by Varmint Al. Dunno if each mfr can spec their brand just as scope marketers spec different scopes made by one OEM Optics mfr, but I suspect they do since there is a big difference in how each brand shoots.

Must be so,  The Hornady and the Federals both use the V-Max head, yet perform differently in my rifle.  Had a perfect no wind day yesterday and got a couple of 3/8" groups at 100 metres with the Fed.  Hornady gave a group of 1".   Point of impact changed by about an inch as well.

Heh heh, maybe it's just the tip color and head stamp that makes em shoot different!!! Remington also uses the Vmax as well as CCI, rem is gold, CCI is black just like the fed, dunno for sure, but they all shoot different in 4 different hmrs that I have. Each has it's favorite, but if I had to give the nod to one that shoots decent in all of em, it would be the Hornady, and since they did all the R&D on the cartridge, that only seems right that theirs out performs the others.

I haven't tried the Winchester version or CCI FMJ yet, but if I see em on a shelf, I will!!
