    Hornady 129 gr Sp Interlock load data.

    I just bought 100 Hornady 129 Sp Interlock bullets to try to work up a load for a heavier bullet. I'm having trouble finding a recipe for the powder that I have the most of. I would like to try to use H335 with CCI 450 primers. I will be using new Hornady brass. I do have some CFE 223 as well. Does anyone have a good starting point for any of these combinations? I also have a bit of 8208 XBR.

    I think your best choice would be the CFE 223 based on what you have available. People have also reported good results with AA2520 and Leverevolution with heavier bullets.

      published data for CFE223 available.

      Per Data available in the Hornady 9th edition only CFE 223 is listed. CFE under that Bullet combo starts at 27.9 grains and 31.7 grains is listed as a max charge. These charges yield 2000 to 2300 fps from a 18" barrel in their test over a WSR primer. Usual safety precautions starting low and work up pertain.

      BLC is another popular powder listed.

      Seems LVR is another powder gaining momentum with the Grendel crowd W some High marks for Velocity & accuracy. Cautions w LVR seem to be coming from Hodgdon themselves specifically stating they cannot recommend LVR for the Grendel at this time. I dare venture to say simply due to a lack trial run having been run yet. Hodgdon does not recommend CFE 223 Either for any application in the Grendel. Lots of folks are liking CFE 223 in the Grendel.

      Personally I have tried LVR in a 24" bolt action, behind the 129 gr SP bullet With good accuracy with little pressure signs dare I say less than I have observed with other propellants I have tried. I can say I have also experienced more recoil. Then I would expect more recoil w more velocity and heavier bullets. I see this as deserving more work up in the future. Positives I see W LVR are less pressure signs, Greater velocity and good accuracy. Should make for long brass life in my opinion.

      Some have claimed LVR tends to leave the AR action dirty. given the fact I am working w the bolt action I can not speak to dirty auto action issue from personal experience.

        The 31.7 grains seems heavy, especially when considering that much CFE is compressed with the 129 gr SP.

        On the other hand, I got about 2400 fps using 31.0 grains of CFE 223 in my 18" barrel using the flat-base 129 gr SP bullet.

        It should work beautifully on game out to over 300 yards with an MV of 2400 fps or 250 yards with an MV of 2300 fps.

          I stopped at 30.3 of CFE223 with my 129gr progression. Somewhere between 30 and 30.3 seems to be a good node out of my 24" overwatch. 2530fps was all I was able to manage out of that pill. I have since dropped back down to the 123gr.

            Finally got some bench time in

            Focus tonight was bullet performance on water jugs / poor mans ballistic jell.

            Tonights bullet was the Hornady 129 gr Spire point.

            Firearm is a bolt action CZ 527 W a 24" 1 in 9 twist barrel.

            Only 2 loads tested on water jugs, Sorry no Chronograph.

            1st load
            Virgin Lapua brass
            129 grain SP over 29.5 grains of WW 748 seated at 2.249". CCI 450 primer
            Results were a beautifully mushroomed bullet in the 4th jug with a retained weight of 109.3 grains. This yields roughly 85% bullet weight retention.
            distance to target from rest was roughly 95 yards.

            2nd test was similar to the above test with the following exceptions.
            Note: Neck sized only brass 3 x fired Lapua. Lee collet Neck size die, Yea no lube!
            Powder 32.6 grains of LVR. Powder settled w an electric tooth brush. Slightly compressed load.
            protruding dent in the off side of the 4th jug. Bullet still in the 4th jug.
            bullet weight 92.8 grains whitch provides roughly 72% retained weight.
            the 32.6 grain load of Lever was showing no signs of pressure.

            Anyone care to guess where I am leaning for a deer load for this season?

            LVR too slow for that application. My azz!

            I feel these loads to be safe in my firearm and no assumptions should be made as to whether this load data may be applicable to your firearm. Another words general disclaimer, start 10% low and work up.

              I'm bumming, I just checked the head space on my build and it failed! I think the Faxon bolt may be out of spec. They're going to send me another one to check it. The go gauge was causing the BCG to stick out a good 3/16" when the bolt should have been closed. Anyway, I just picked up some 120gn. Gold Dots and 129gn. Hdy. Interlocks. I don't have any LVR powder but I do have 322, 223CFE, and WC846 (basically the same as BLc-2). I finally got my hands on some Starline brass and actually have some LR primers so I'm looking forward to tuning the gas block and compensator so I can Zero this thing in before deer season!IMG_20210617_192231 the grendel.jpg At least that's what it looked like before I had to tear it apart.
