    I applied for and received 2 boxes of Bergers 250gr Hybrid OTM Tactical for testing and here are my results. :) I like them.
    This pic should keep you interseted. The final tests were shot at 560 yds. the longest distance I can shoot at my range. This group was shot at that distance with 91.5grs of IMR 7828SSC at 3160 fps. It was sighter group for testing to get on target.

    I decided to use powders that I already have that I used with the 225 gr Barnes TTSX testing. I don't know if this matters but Broughton says my barrel bore was .3385 so I have been using a little faster burning powders to slug up the bore ( so to speak )
    The bullets have a G7 BC of .349 and a G1 BC of .682 I weighed them and out of 100
    72 weighed 249.9grs
    10 weighed 249.8grs
    15 weighed 249.7grs
    3 weighed 249.6grs
    I didn't go thru the trouble of measuring them, length or ogive, but I did notice the tip ( or hollow point ) on some of them was at an angle, not flat, but that didn't seam to matter in my tests. I have a friend that got a tool to make the tip of bullets flat or uniform on his 6.5mm Berger VLD's and did some tests and at 500 yds it didn't make any difference. ( and that gun would shoot 5/8th's inch groups at 500 yds all day long)
    Here is a pic of the bullets I have shot before

    how do you apply to test bullets and other gear?

    It was posted on Accurate Shooter ( that is where I saw it ) and on snipers hide websites.
    I asked Michelle Gallagher who is the marketing person for Berger bullets why there and not here on long range hunting. She said because it was a target bullet and not a hunting bullet. Michelle said when they come out with the hunting version it will be posted here. She said it will be available to 1/3 if the people who apply to test it.

    How long ago was it when you saw it? I will keep my eyes open.

    I forgot to mention this but my rifle is a 338 Rem Ultra Mag.
    I am using once fired brass that I bought new. It has been prepped and annealed. I use a Lyman full length die that I honed the neck area to give me .003 neck tension. I use a Hornady new dimension seater die that has the sleeve inside that holds the bullet straight in line with the neck. I made another sleeve and honed it to just let the bullet fit to get tighter tollerances while seating the bullets in my cases to keep the runout at a minimum. I weigh every charge.
    I started out with IMR 7828SSC
    Fed 215 Mag primers
    I loaded from 87gr in 1/2 grain increments to 90 gr. seated .050 off the lands.
    Testing was done at 300 yds. The 90 gr produced a 1.034 3 shot group at 3020 fps.
    I tried some more at .015 and .070 off the lands with the 90 grs and the .070 produced a group just under an inch at 300 yds. I loaded some more up with
    90.5 91 and 91.5 grs and the 91.5 gave a little more velocity and grouped as well 3 shots at 1 inch at 300 at 3160 fps.

    I also tried H 4831SC
    Fed 215 Mag primers
    I loaded in 1/2 grain increments from 87.5 to 90.5 gr seated .070 off the lands.
    The 90.5 grouped the best despite the wind and mirage that day with 3 in 1 1/4 inch at 300 yds at 3060 fps. I know I can still go higher with the 4831 but with the amount of bullets I was given, my load development was limited if I was goint to stretch them out to 500 Meters.

    I loaded up 15 with 91.5 grs. IMR 7828SSC and I loaded 10 up with 90.5 grs. H4831SC for my testing at 500 Meters ( 560 yards at my range )
    I used my go to load of 92 grs. of H 4831SC with a Barnes 225 gr TTSX at 3217 fps to get on target at 500 despite 3.5 to 6 mph winds.
    [​IMG]
    I had to come up 6 MOA on my scope ( 48 1/8th clicks ) from my 300 yard setting to get on at 560 yds.
    I shot three 3 shot groups with thw IMR 7828 SSC first letting the barrel cool down to outside temps between shots. Temps started out at 62* and wind was from right to left from 3.5 to 6 mph. These first 2 groups would of been really small if the wind didn't play havock with my testing.

    I really like how these bullets show very little verticle variation.
    I then shot the ones loaded with H 4831SC. The wind had changed directions and the mirage was moving my 3 inch orange dot around about 3 inches. The temps were at 70* and the wind was from left to right now. I tried to shoot when the wind was blowing the mirage away so I could get a more accurate ainimg point. I even cut the power down on the Burris to 24x.
    This was the last group of the day and was the best with this powder.

    I am going to do some more testing with these bullets when they come out in April. I really like how they shot and my barrel clean up was really easy. I didn't clean it till after the first 70 rounds and after just a couple patches of Bore Tech eliminator the patches came out clean. I even soaked it again and let it sit and the patch had hardly any green on it. I hope to try these on elk if I get drawn ( just put in for a cow tag here in Az )I would like to try some 4350 and go a little higher with the H 4831SC.
    I would like to thank Michelle Gallagher from Berger for giving me this opportunity to test these bullets. I like the short bearing surface compared to some of the other 338 cal. bullets that will let these be shot at higher velocities and the accuracy is there. I can't wait to get some more.
    PS: I an going to try some of the 168gr 308 dia. Hybrids in my 308 Win.
    Hey guys, keep your eyes posted because Berger is going to be doing some more testing when they come out with the hunting version of these and you could be one of those testers.

    Gnergy,
    So these are thick target jackets? Anyone testing them at 3500 fps plus that the 338 Cheytac variants will push them at?
    Thanks,
    Greg

    Berger says the jackets are the thicker target jackets at .025 thick.
    MT4XFore said he had been shooting them since last summer when Kirby Allen had been given some by Berger to torture test at higher velocities and they held up. Kirby gave some to him and he took 2 good mulie bucks at over 300 yds with good results. He shoots them out of a 338 Allen express at 3200 fps.
    Bros has been hunting with the 300 gr Hybrid all last season and has taken some nice elk and mule deer with it and he really likes it.
    I can't wait to get some more of them to fing a good long range load.

    Tarey,
    Yea, we've been shooting the 300gn Hybrids out of our 338 Lunatics at 3250fps since last July. We've taken Himalayan Tahr, and Red and Sika deer to 1200 yards so far with them, and they've killed superbly. If the 250's have the same jacket thickness, they should work just as well terminally. They will probably come into their own in the small to medium 338's, like our 338 SF and 338 Thor, which will push them from 3300 to 3400fps. Especially in our lightweight walkabout rigs that only weigh 8 lbs all up including the scope. The recoil reduction will be very welcome! In the likes of the Lunatic, Kirby's AM etc, the 300's will still be the "go to bullet" I'm sure.
    Thanks for you info,
    Greg

    Sorry, I've posted our results on here a bit but obviously everyone hasn't seen them. The Lunatic is our version of a 338/408 improved, inspired by Kirby's 338 AM. Got its name because some said when they saw it "you'd have to be a lunatic to fire it!
    The 338 SF is sort of a 338 Lapua improved. Stands for super fatso, as its a full length 338 version of our 7mm Fatso. The 338 Thor is a 338/416 Rigby improved.
    If you looked back thru my posts, you'd see a few pics I think from memory. Especially on my posts about the terminal performance of the berger Gen II 300gn Hybrids.
    Thanks,
    Greg
