H4895 6BR temp stability ???

[Eric Leonard]

I shot a couple targets today that were very good from 6BR with the 105VLDH and H4895,,at almost 2900 fps at 29.6 grs,,,the Lapua brass and Farley action seem to hide pressure well but this has to be a warm load,,,,when it heats up here in the south I am sure I will have to back down but will the accuracy still be there as long as I can stay in the same speed at a lower charge,,

shot without chrono on rifle and 2 5 shot groups in a row were @ .500 at 300 yards,,

I ordered some good custom flags should be here tomorrow and hope to try it all out at 600 Sat hopefully,,

anybody use H4895 year round with good results??

I have used H4895 in varying humidity and temps ranging from 20F to 95F in both 6BR and 22BR. I do not recall ever experiencing any temperature/humidity related issues. Backing down a little on the charge will be necessary during high temp use but the accuracy node should not shift too much if at all.

Tried your load of 31.5 h4895 at 40 degrees and stiff wind, fed 205 m primers-5 shot at 300 yards, 105'JLK vld'=3/4 in group. Had slight ejector mark on some of Lapua brass. Will lower to 31.4 and see how it goes. Ordered 8 pounds of h4895. Thanks for aiming me in good direction.

My wife is running 29.0gr of H4895 with a 105 vld at 2836fps. We shoot at temps from the high 30s in the winter and well above 100 here in the summer. H4895 has proven to be very stable in those conditions. We shoot to 600 consistently and her come ups are the same winter or summer. It's good stuff.
