Leupold BX-4 Rangefinding Binoculars

Deep throats and tangent tips: a 22-250 FT love story

Only three for the initial tests. Just enough to show me where to look closer.
Thanks for sharing. I'd be interested to see if the local maxes and mins would still be in the same place if the test was repeated. I would imagine the overall trend line would be similar, but I do think that alot of behavior we see during load development can be attributed to variance due to small sample sizes.
Not expecting you to burn a bunch of components just to humor me.

Thanks again.

You’re exactly right. In the seating depth test, a “bad” 3 shot group tells me more than a “good” one. In all of these, I then loaded 5 of the top two candidates to compare, and a 10 shot with my final ELDM charge. Haven’t done that yet with the SMKs. Afraid to ruin my IG brag pic. 😂
 
Bering optics super hogster. What are you looking at and what are your plans for it
The cheapest, most basic I could find was the ATN Thor LT. Doesn’t have any bells or whistles.

I would use it for coyotes on my folks’ place which is both a cattle farm and our main hunting land for both whitetails and turkeys. Coyote numbers have really been growing there the past 5 or so years.

It’s honestly unlikely I will get one; but definitely on my wish list.

I’d steer clear of the cheaper ATN.
 
Here were my final recipes:

80gr ELD-M, Lapua brass (1.90”), WLR primer, 36.1gr of H4350, COAL 2.710”, 3215fps.

77gr SMK, Lapua brass, WLR primer, 36gr of H4350, COAL 2.580”, 3230fps.

77gr SMK, Lapua brass, WLR primer, 32.4gr of Varget, COAL 2.540”, 3100fps.

Worked out drops today. Here was 400. Flat shooter! (-19.25”)

I forgot to mention earlier, I started using barrel temp stickers during load development to maintain consistency in that as well. I chose 113F as my top end and resume again at 95F. Fwiw.

Found some factory ammo locally over the weekend and decided to give it a try. Hornady Superperformance 50gr Vmax. Shoots minute of groundhog ball sack and is smoking! Zero at 100, drop at 400 is 16.7”.

Haven’t started to reload for it yet but it’s showing promise with several of my old loads. Can’t wait to see what 6.5 staball and the heavyweights can achieve. Sorry but not sorry @brockel if I shoot some of your coyotes and antelope with it next week.

Try a faster powder.

Like h4895 or similar. I went to Accurate 2200 on my .223 Remington and the groups are sub .5 MOA and I still need to tweak it. Look at the weatherby rounds too. They are running a 0.378” freebore on them and close to a 0.100” jump on when loaded to the ogive.

I actually cast my .260 Remington chamber which lead down the rabbit hole you’re discussing on bullets seated only enough to get the base seated to the extreme of the bullet into the neck.

It’s 0.150” freebore compared to the saami spec of 0.1185”.

The pulleys set to the green position are 6.5mm barnes Match burner and Hornady ELD-M. They would need a freebore of 0.320” to be seated there. And be 0.020” off the landing

The brown tip is a nosler Ballisti-tip. It would need a freebore of 0.520” The OAL on both would exceed that for a short action magazine and have to be fed single shot or be built on a long action.

I have to admit....I’m lost. How does this connect to fast twist tikka 22-250s.?

Because we’re both doing the same thing with freebore and seating depths.

Weatherby does the same thing with most of their calibers.

With a LONG freebore, you can get a much greater jump allowing much greater velocity with lower pressures.
