    H4350 vs Imr 4451 charge for equivalent load

    I did a load dev with IMR 4451 and 147 ELDM in 260 and with a 26" barrel and 41.7gr of IMR 4451 I'm getting an average of 2786 fps. I finally got my hands on some H4350 and I'm trying to come up with a new load. From what I've read, you need less powder with the H4350 to achieve similar...

    Rifle Scopes Kahles Gen3 624i Review (Amazing Optic)

    I have a Kahles Gen3. I can set parallax at 600Y and not touch it during a match. Even at max magnification, everything will be clear between 400 to +1000Y.

    223 Hornady 75gr ELD Match: better than 175 SMK 308?!

    As I previously mentioned, I did chrono the load (Magnetospeed) with 24.4 gr and my actual MV was 3021fps. So, he's only getting 124fps less.

    AI AT barrel replacement

    The price is very competitive. Too bad they don't make any AIAT barrel in 260 (at least it's not showing on their web page).

    McMillan or B&C (Tikka T3x CTR)

    Can you please elaborate on this? I don't own any McMillan / Manners. I do own a B&C Medalist with the alu block and it seems to work fine. I'm just trying to understand what practical gain will get over a B&C stock. It will be lighter...that I can see....but what else?

    MDT .223/5.56 magazines

    MDT 223, 10 round mags suck. I had issues, especially when loaded to max capacity. I was getting bullet tips diving into the mag. I switched to accurate mag and all is working fine.

    Help me diagnose symptoms with my AT

    The increase in the pressure of the previous load might have modified the geometry of the extractor.

    Help me diagnose symptoms with my AT

    Your barrel has increased in speed and is showing pressure signs. This is pretty common. Do another load dev with lighter charges.

    223 Hornady 75gr ELD Match: better than 175 SMK 308?!

    When I mentioned 3070 fps it was an estimate. I actually did a chrono last time and got an average of 3021 FPS. The bullet isn't jammed. It has a jump of 0.01".

    223 Hornady 75gr ELD Match: better than 175 SMK 308?!

    2.390" seems to be a good start. It's best that measure the throat though. I load mine at 2.420". With that OAL I get a bullet jump of 0.01"

    Wrist Coach for PRS match: Not comfortable.... Any alternatives?

    The pic I posted above is my rifle with the Python and 3D printed pic rail I received and installed today. I ordered it directly from his site and there is the option of ordering if with the 3d pic rail adaptor. http://www.sidewinderindustries.com/

    Wrist Coach for PRS match: Not comfortable.... Any alternatives?

    I got the Python with the "3D Printed Pic Rail option". So, the "the 3D Printed Pic Rail option" is a plastic picatinny rail adaptor that has a hole for the Python to wrap through if you don't want to wrap it around the scope or rings. The whole setup is pretty nice. I definitely prefer this...

    It's 0.13 mils. I took the PDF of the SMKR3 and zoomed it on my screen http://www.kahles.at/verwaltung/uploads/20170109185159K624i_SKMR3.pdf I took my caliper and measured the first known subtension. I got 0.231" corresponding to .2 mils I measured the distance that you were asking and I got...

    Wrist Coach for PRS match: Not comfortable.... Any alternatives?

    I'll definitely go with a weapon mount. I was thinking of getting the Python and attach it to my front scope ring. I'm not sure what's the "3D Printed Pic Rail Attachment" option on his site (dropped Marcus an email and asked him the question).

    Wrist Coach for PRS match: Not comfortable.... Any alternatives?

    I like it. I'm not sure what's the purpose of the painters tape. You could make some and sell them here.

    Rifle Scopes Kahles SKMR3 Subtensions

    Each of those subtensions is 0.2 mils. Your black lines are each 0.1 mils (half of the Kahles subtensions).

    How much freebore is too much?

    That's too much. Then you'll get some throat erosion and it will make it worse.
