    Is anyone using this combination? If so, what were your results?

    I use rl22 or I 7828 myself if either 165 or 180gr. pills are on the menu in a 300 win.
    I save the rl25 for my 300 rum with 180's. rl25 is do-able but you will have a rather compressed charge. Should shoot like a house a fire though.

    I use 180 grain Accubonds and 73.5 grains of RL-22 for my 300win mag. Out of my 25" barrel, I get overlapping holes...about 0.25". Keep in mind the diameter of the bullet makes up a lot of that 0.25"! I could maybe tweak it a bit and get holes inside of holes, but when the net result of a 5 shot group is just one hole (not perfectly round, though), I'm satisfied. I may come back and tweak it after my LR class this fall though.

    Personaly i use re19 more in the 300win then any other powder. It may be a tad fast for the use but its given me the best accuracy. Re25 might be a bit slow. Truthfully something like re22 or 7828 might be about ideal.

    I have had great luck wih 80.0 gr of RL 25 with 180 accubonds and partitions,Fed 215 primer, around 3,100 fps. Shot this in many rifles.

    RL25 is a bit slow, even H1000 is a little slow for 180s both will be tightly compressed loads. My personal favorites are Imr4350 and H4831, although AA3100, RE22, Imr4831 and 7828ssc, and VV N160 or 560 are all respecable choices.

    I forgot to mention that my velocities are about 2985fps...I could push it more, but if you check the velocities on Nosler's premium factory hunting ammo that uses the same Accubond that I'm using, my velocities are almost dead on equal. I actually prefer this- my accuracy is great, and I'm not spending $60+ per box of 20 rounds...but if I had a problem traveling and my ammo was lost, or prohibited for some reason, I know I can walk into most LGS or big box shops and pick up some of the premium stuff in a pinch without having to worry about a drastic change in ballistics. Just another something to think about if you're building a hunting rig...

    I used to have a ruger tang safety 77 in 300 win mag. It had a long throat. Its favorite 180 gr. load was 82 gr RL25, fed 215, 180 hdy flat base interlock spritzer. I think I was using win brass. Anyway, velocity was around 3130 fps. The load was a compressed load but not to the point of having to use a drop tube. I was using this around 1997 or 1998. As with all loads work up from starting charge weights watching for pressure signs in your particular firearm. In the ole ruger this load was consistent and accurate and exhibited no pressure signs or bad manners (ie- good ES).

    I recently bought some RL25 off a buddy at work and have some 180grn test rounds loaded up for my .300wm. Looking at my load data from my Lee die set it looks like RL25 gets a little better velocity then H1000 which I've been trying as well. I hope it does well, but I hope to get some heavier bullets and try it behind to.
