While I cannot say I have used the 90gr XTP on game I did load some up for testing when working up loads for my grandson.
I found however from my rifle that they were pretty erratic in both accuracy and velocities. I am guessing this was due to the short bearing surface. They are pretty short for loading in a rifle but are great in my Ruger .30 Carbine.
I found that the best over all performance was with the 130gr bullets from several manufacturers. I ended up using the 130gr Barnes TTSX and they did everything we needed doing. His load was using 42grs of H-4895 and with the 130gr bullets we were getting right at 2650 from the 16.5" barrel on the Ruger Compact. Accuracy was under 1" groups at 100yds with me behind the trigger and with him sometimes the same sometimes a bit more. But for a 4 thru 8yr old I wasn't complaining. Here is a pic of two shots he made on one of our plates at 180yds with the Barnes,
Without the cross wind he would have been spot on the bull, still good enough for the hogs we were after. And yes that is two impacts together by a 4yr old at the time.
I highly suggest trying this bullet and the Hodgdon loads out. When testing I used the loads on feral hogs out to around 200yds and with good placement, and even a couple of not so well placed shots the little Barnes pill rocked their world.
The other bullets I used in 130gr range were some bonded core handgun bullets from Alaskan Bullet Works,
Very good bullets at these velocities. Couldn't tell you how well they opened up as they went never stopped in the shots I made on three 150'ish pound hogs. I can tell you they went through both shoulder bones and all, and left half dollar sized exits.
I also used the Speer 130gr Spitzers, and also some 130gr Wildcat Bonded Core.
Like I mentioned I was so impressed with the Barnes and with the availability being a considered factor they won out. The Speer shot OK, and could have probably been tinkered with and brought around to group as well but we were at the time working against the clock to get the load worked up in order to practiced up for hunting season. With a kid of 4yrs old that meant LOTS of trigger time. We used a lot of 125gr bullets for practicing then switched up to the Barnes a couple of weeks before the season opened. He did however get his first hog with a 125gr Nosler BT, but after hitting a coyote broadside and not getting an exit, we bumped up to the 130 and never looked back.
Good luck with your loads, hope this helps some. Like I said those 90gr XTP's might work out for you, but in my rifle they were just a bit too unpredictable.
