    .450 bushmasters 16” vs. 22” ruger?

    Finally got around to doing some load development w the BCB 240 HV w H110. This is the pressure test run .5 gr increments on the new rifle. The load that hit 2513 fps showed the start of primer cratering.

    What barrel manufacturer are you and Harry running? I’m using Bartlein modBB 1-7.5 w 0 issues!

    The new 33XC & 37XC cartridges designed by David Tubb

    Start at 110 gr N570 w BL 285 and work up. I ran them up to 120 gr during pressure testing in my rifle. The BL 285 2 loads I’m running is 115-116 gr N570.

    The new 33XC & 37XC cartridges designed by David Tubb

    I have shot about 300 of the BL 285 ICBM-2s in a ModBB 1-7.5 twist w n570. Load development was easy, easy to see your hits on steel at distance. To date the only bullet I have hit 3 out of 4 at 2315 on a 24x24 target. I will continue to use the BL 285.

    DNA cases are great. I use one w the 33XC. Worth ever penny.

    What velocity? Spoke to Bartlein last week. 375 blanks are scheduled for late fall production. Going to be next year before I get into shooting the 37 XC!

    Rifle Scopes Tangent Theta 7 - 35 X 56, new hotness in hand

    My buddy just received his TT 7-35 earlier this week just to send it back 🤣. His quote “ I don’t remember sending any of my NF scopes back”,, is NF the only manufacturer that does a 70 plus point QC inspection before sending out a scope?

    I would like to add one more observation, call me crazy but I swear I get a silver flash in the scope upon impact w BL SBD2.

    Wow, I would be extremely pissed, RCC was priced like gold! I'm still waiting on the rifle.

    Pros and Cons of 33XC vis a vis 338 LM

    I prefer to eat my cream of wheat, i always loaded up a 100 rounds and banged steel allowing the barrel to start to speed up before load development...100 Lapua cases annealed will last a barrel. Load up virgin cases and use those loads to foul a clean barrel, set them aside for future use. Easy

    7prc brass

    I lucked out and grabbed 100 pieces from RCC before they went bankrupt. Peterson will be the go to brass in 7 PRC.

    Do the CE leave a nice wide splatter on target? Can you post a pic? I have a 375 cal barrel coming for 37xc and haven’t settled on a solid to start with.

    37XC Build

    I posted some pics of hits on a 24x24 plate we use out to 2450 yards. 338 Berger’s vs Badlands vs Warners. I can see my hits and misses w the scope w Berger and Badlands, both leave a nice splatter on target! The Warners being a much harder alloy are hard to see the hits on plate but that’s what...
