87g Speer TNT HP

[remingtonman_25_06]

recently picked up another 25-06 rem, this one being an older Rem 700 BDL wood/blued w/24" bbl. I got it used and have only tried 100g and 117g gamekings w/IMR-4350 and IMR-7828, the best I've gotten at 100 yards is .8". I think the rifle can do better and I really haven't gotten to extensive in my testing yet.. I have an older style Leupold vari-x2, 3-9x40 with the elevation target knob. It gets me out to 800 yards, but I like a little more magnification. It will have to work for now...I have only shot it out to 400 yards, but I was 6-6 on my 10" gong the last outing with the 117g SBT/IMR-7828 load.

This rifle has probly been through some use by the way it looks stock wise, but I intend to use it as a truck rifle for coyotes. I haven't ever tried the 87g TNT HP, but the BC (.310) isn't that bad compared to the 85g NBT (.331), and there a heck of a lot cheaper, about $5 less per 100. I should get a little more explosiveness out of the TNT as well, its got a pretty nice size hollow point. They say not to be pushed harder then 3600fps. I"m hoping for 3400-3500fps with good accuracy.

Anyways, just looking to see if anyone uses this bullet for coyotes and what the results were like? Also what kinda loads did you use??

Thanks for the info guys..

Remman,

Why not use the 100 gr BT for everything?
You can get seconds pretty cheap too.
