I loaded up some 9MM's I used Hp-38 = 4.6 gr. and 115 FMJ, like I always do, then I noticed I used small pistol magnum primers...wha will this do to my loads or what can I do now

HP-38 = W231 IIRC. My data shows you at the starting charge. I would shoot them. Start with one and look for pressure signs, odds are extremely high there won't be any. Shoot a few more and check, then blast away,

I don't do 9mm BUT...
I have always been told that "magnum primers are the equivilant to 1 grain of powder". If you are at a minimum load, you should be OK.

Another consideration is what you are going to shoot them in? Personally, I would run them through my Glock before I'd test-hop them in an old S&W Model 39.

I've used mag primers in place for standard primers and really didn't notice any difference. But I don't load hot!

These 9mm's was to be used in my Ruger p95

I often use magnum primers in non-specified applications; in your case (oh, I love it!) you will be safe.

But I don't swap willy-nilly and I understand that pressure can increase 5,000PSI and certain loads will react differently (but I do often use mag primers in certain 9x19 loads).

NOT RECOMMENDED; your results may vary.
