Mr. Ingwe. I'm sorry for my rude reply yesterday. I found a bunch of Elevator IPA yesterday and I accidentally drank them all. My behavior was altered accordingly.
I use H4895 in two different .223's. With both the 50gr V-Max, the 53gr TSX, and the 50gr. TTSX. I have achieved fine accuracy and have not experienced any dramatic shifts in speed or performance due to temperature change.
I trust you'll find this information a bit more helpful.
Your friend,
Travis
