[QUOTE="swampratt, post: 3467629, member: 15054"] I was heading out yesterday to shoot and do a little hunting and wanted to try some N133 in my AR15. I need a squirrel round. I thought I grabbed the 55 gr box of Nosler bullets but pulled the lid on some 40 gr boat tailed ones. My load is not a max load even with 55 gr according to some load data books. I did notice they looked quite short and seated very easy compared to my normal 55gr V-max load. After I made a round i stopped and double checked the box of bullets. Ouch 40gr. EEEHHHH ....Go for it is what my head said. I looked at load data and i was below max by quite a bit 24.7gr N133 CCI 450 in FC cases. I also took some old loads of 55v-mag and 26gr of H4895 I had built for my Bolt bun that were seated 2.278" and seated them to 2.253" same as the 40 gr load. That is a severely crushed amount of powder at 26gr and for my AR load I use 25-25.5 gr. First shot out of the gun was high and right. I do not know when the last time I shot it was and it was put away dirty. I usually drag a bore snake through my dirty shot rifles a few times before shooting for a group but did not do that this time. The 55gr did not do so well and I expected that as I have tried that 26gr short seated deal in it and it was not great. I pulled one shot way left and high and knew it when i touched off the trigger. Yea I screwed that shot. I shot the 40gr loads first and numbered the holes after the loads were shot. Now this was only 85 yards but it does show promise with that 40gr and 1:7 twist barrel. Shots number 2 3 and 4 are under 1/2" center to center which are the 40gr bullets. [URL]https://www.midwayusa.com/product/1758562732[/URL]. I will be making more and testing again.
