I've been trying to develope an accurate load with some 200 gr Hornady JHP, and it has been awful so far. 4 inch groups have been the norm no matter what loads I've tried.
I have IMR4227, H4227, IMR4198, H110, W296, WC820,WC680, Unique.
I am shooting these in a Model 96 Ruger rifle.
Any load suggestions?
The 200 gr' bullet may be just a bit too light, or too thin of a jacket, to develop good pressures with the powders (and primer?) you are using. The .44 likes a strong crimp, and probably somewhat heavier bullets if you're using a Remington large pistol primer. Rem' primers in the large pistol are relatively weak.....
I'd go with Win' large pistol (reg/magnum) primers, a 210 gr' JHP Remington bullet, Rem' brass (better crimp with it), WC-820 in high loading density (very important), and a firm crimp. Use only a very narrow flare to get the bullet into the brass.
Many guys have had mixed results in the .44 mag' with Unique -- from what I've read. I have some, but have not tried it, since WC-820 works so well for me. Blue Dot powder has also given me good results with some bullets......and is a good option with a lighter bullet in this cartridge.
You may also want to post this concern on one of the other topics on this site to see how well others are doing with that Ruger Model.
Good luck.
