    1. Just plain wow

      So i took these out to my favorite BLM spot deep in the woods of Colorado. Set up targets and got out my Caldwell Crono. Ran these against Hornady LEVERevoution 325 gr FTX. my numbers on 5 shots:

      LEVERevoution : AVG FPS: 1943.7, FT-LBS: 2725, Momentum 90, Taylor KO: 41

      Xcaliber 300gr JHP: AVG FPS: 2238.8, FT-LBS: 3338, Momentum 95, Taylor KO: 43

      Gun used: Marlin SBL 45-70 Guide Gun, 18. 5 inches.
      The difference between the two as far as energy, momentum etc:

      I paid $35 a box of 20 for LEVERevoution at Sportsman's Warehouse. What is that $1.75 per round, what are Xcaliber's comming in at for price???

    2. Excellent Ammunition

      It'd probably shoot a 1" or less if I did, but given that I'm still fairly new and shaky at my 45/70, 1.5" will have to do. That being said, it shoots much straighter and more consistent than Hornady LeverEvolutions, which used to be my go-to load. Costs less too. I'll let you know how it turns out when elk season rolls around. on Apr 11th 2018

    3. Great Quality Ammunition

      I was very pleased with the product arrived within bout 4 days after ordering and in excellent condition. Accuracy was awesome I put 3 inside a quarter at 100 yards. Now their pretty warm far as recoil goes kinda surprised me a little bit so I would keep a tight grip on the rifle when firing cause it will ring your shoulder. I will be ordering from Xcaliber again this fall. on Feb 10th 2018

    4. Great ammo at a great price

      I had just picked up a Marlin 45-70 and was looking for ammo on-line. I ran across XCaliber and decided to give it a try. As this was my first time shooting 45-70 I had no idea what to expect. Took less than 10 rounds to sight in my new scope and from then on all shots were in the X ring. Fantastic ammo. I don't reload but the range master where I shoot does and he was very impressed with the brass. Keep up the great work guys I will be buying more. on Feb 10th 2018

    5. Deadly at both ends.

      These loads are very accurate, and powerful enough to take down any animal in North America. I did get a touch of PTSD from the recoil, but it's a little gun and a big bullet, so it is what it is. I would not hesitate buying more or recommending to a friend.

      XC Response 2/3:
      Glad you liked them, Joe! We are close to developing our "Goldilocks load" that has a power factor between this slobberknocker and our trapdoor safe loads. Stay tuned!

    6. Power accurate

      Powerful accurate good price/value on Jan 6th 2018

    7. Great value, full power

      Finally some fairly high pressure rounds that don't break the bank to shoot, I love to shoot my big bore but @2.50-3 00/ round for typical hot rounds it looses it's lustre. With this loading I can enjoy a whole box of big bore thunder with out eating ramen for the rest of the week. This70 jhp ammo shoots clean and consistent out of my CVA scout v2. Not quite as accurate as some hot hendershots custom silvertip, but still within 1.5-2"@ 100yds, so pretty dang good. Recoil is the same possibly a touch stouter as the hotter but coated silvertip bullets. on Jan 2nd 2018

    8. Good Quality Ammo

      Very high quality ammo, will be buying again. Shoots great out of my Henry All Weather 45-70.

    9. Great ammo

      After buying my marlin, found these online for a great price. Took 5 shots to get sighted in., one shot to take it's first deer...very impressed with the grouping and consistency of this ammo...Highly recommend!! on Dec 7th 2017


      Fit, finish and function in my Marlin 1895 GBL are all 5 stars. I have much confidence in this round as it penetrated 12" of lumber during my initial testing.. I get a lot of repeatable shots but not as easy to shoot as a BR varmint caliber. Search the internet for a better value. You won't find one. on Dec 3rd 2017

    11. Awesome stuff!

      Accuracy was way better than I expected. Shot almost 1/2" groups at 100 yards, which was tighter than the leverevolution that I usually use. Great ammo, great price, best value out there! on Sep 26th 2017

    12. Great ammo!

      Cosmetically perfect. Packs a wallop. Acculturate enough for my applications. on Aug 20th 2017

    13. Not tested

      Although I have not used these rounds yet, they look of good quality and the price per round delivered for new rounds is unbeatable. on Jul 7th 2017

    14. Would definitely buy again

      Great experience. Ammo delivered really quickly. This is a beast of a load, but it shot accurately out of my short barrel lever gun. on Jul 7th 2017

    15. Excellent

      Nice groups , lots of power ! Packed in a nice reusable box.

      From XCaliber 7/7/17: We're glad to hear you had such a good experience! Please note we are currently working on a custom box for our 45/70 loads now. In the meantime, you will receive either a smoke (gray) MTM hard plastic box or a generic white folding carton with styrofoam tray.

    16. Accurate and powerful

      Turns clay pots to dust . Cant wait for deer season! on Jun 20th 2017

    17. Very, very accurate!

      Shot a sub MOA group out of a Marlin 1895 45-70 rifle using this ammo. This load is purely awesome! on Aug 23rd 2016
