    "300 BLACKOUT tell me about your pet loads"

    I don't use the 300 BLK for pets,,,,,,,I like my pets,,,,,,

    Lee 155 SKS and the 310-196 FN MX2-30H, both sized .310 with 15.7gr of Reloder 7. Plenty accurate to 250Y.

    20gr H-110 and a Hornady 110gr ZMax. Most accurate supersonic load I’ve had to date.

    Caution: depending on source, this is over max, other sources it’s not. Shoots fine in all my guns with no pressure signs.

    the rcbs 165 silhouette on top of 9,5grs of AA#9 has been real accurate.
    the LEE T/L 240 in the 7 twist on top of 3.5-4.0grs of fast powder with a rifle primer seems to be pretty universal [sub sonic too]
    I really like the Nosler Varmageddon 110 on top of 17.5grs of AA-4100 too it's a P-dog Bunny remover.
    the Hornady 110 V-max is right there with it, just not quite as good.

    My findings and a "pet" load of mine as well, go with 18 grains and work up.

    Reformed FC brass, CCI SRM primer, 15.0 grains of Winchester 296, with bulk Winchester 150 grain PP bullet. Mild and accurate in my Remington 700 carbine.

    15.3gr H110/W296 under a lee 155gr .312 sized to .310. For subs I shoot AA1680 and RL-7 at around 1050fps (somewhere in the neighborhood of 10-10.5gr of either). All of these loads cycle my carbine length gas and my sons SBR with pistol length. I have played with RedDot and Unique with 155gr lee's at subsonic in my 7 1/2" Encore pistol barrel with suppressor.

    15.5 grs of W296 and a 150gr Speer HotCor FP is my current looking for a pig load. The 110 VMax over LilGun shot great. I haven't nailed down a boolit load yet and I have no need for subsonic. The .300 BO is a great bullet disposal cartridge for those partial boxes you find on the bargain table.......
