56 gr RL-17 with the 140 Bt gave me 3140 and groups in the .2-.3" range. Jumped up to 57 gr, .5-.6" groups and 3220 fps. I never really tweaked with it much after that, but it was shooting 2 in and one out. I know in this gun I could have gotten that tightened up with seating depth adjustments...
I had very good luck with RL-17 and the 140 BT and AB in my 280 AI. Might be worth a shot. Some of the best groups my gun has ever produced were with RL-17 and a 14 BT. I see no reason why it wouldn't work for the 140 PT as well.
I was able to get out and play a bit with RL-33 and the 195 VLD Monday. 82Gr RL-33 gave me 3010 fps and a .25" group. I shot 83 gr as well and didn't get any pressure and was running about 3030 fps, but groups opened up.
I would think that you would have quite a bit of room to go up with the 180.
I played a little bit of RL-33 in my STW. I was trying to get the 195 VLD to shoot in my 1;9 twist. I also played with RL-33 with the 180 VLD.
I think there is something up with my STW though. I got a very good group (.2"-.3") with both bullets. Went back to the range to double check each load...
JD, That looks like it is working very well for you. Impressive velocity as well. I ended up settling on 88.5 Gr of RL-26 in mine with a 250 VLD. Getting 3010 fps and .4" groups with it. Very pleased.
I got a chance to play with some RL-26 in my Rum last weekend. I was pushing the 250 VLD out of a 26" tube. I shot 89 gr, 89.5, and 90 gr. 89.5 gave me a nice 3/4" group out of the gate. Es was 18 doing about 3010 on average. That rifle had been giving me trouble for a while, it just wasn't...
JD, I knew that question was going to come..... I'm thinking it is either 60.5 or 61 gr, but don't hold me to it. I haven't played with it in about a year. It shot so good several times I loaded up a box of 50 and forgot about it. A good friend smashed a cow elk with it last august though...
I have 2 6.5 SAUMs now. A heavy one (12 lbs 26" barrel with scope) and a light one (7.25lbs, 24" barrel, with scope) and I love them. In two weeks last year I took Coyotes at 635, 454, 375, 685, 710, and another 375 with the 140 A max doing 3144 out of the heavy one. I also took a buck with it...
RL-26 shoots the 168 ABLR very well in my 280 AI, and is my go to load in it now. I'm getting about 2940 out of a 24" tube.
I also had great luck with 7828.
This is on my short list to get tested, but I have been focused on my STW with the 195 VLD. I'm leaning towards switching to a lighter bullet. I'm thinking my 1:9 isn't going to get it done.
A good friend of mine is using 90 gr of RL-25 with the 250 VLD in his RUM and it is shooting very well...
I'm very interested in this as well. I have a buddy that shoots 909 gr RL-25 in his and it does a really nice job with the 250 VLD.
My 280 AI and both of my 6.5 SAUM like RL-26. Would be good to get it working in the 338 RUM also.
I'm not that familiar with the Huskamaws. I think the turret moving could be an issue for any exposed turret type scope. I know it is an issue on my Mark 4, but it is much harder to turn than the CDS so if it ever gets off it's not much. The easy fix would be to have a zero stop but that won't...
I run several of these scopes. I find them to be a very nice compromise in magnification and weight for the hunting that I do. I run a VX-III 4.5-14x40 LR that I had target turrets installed on my 280 AI. I love that scope.
I recently got into the CDS thing. I have two other 4.5-14x40 LR on my...
