    Has anyone here used the new 3 piece 20 MOA Holland Picatinny rail system with the windage adjustment in the front mount? I've got a LH 700 VS SA .308 Win. that I want to shoot out to 1000 yds. with a 168 SMK Federal ammo with a 3.5X10 MK. 4.. The problem I've got is my receiver holes are drilled off center, enough that I couldn't use DD mounts and rings on this gun as I ran out of windage adjustment in my scope before it would come to center.

    thanks, Pat

    I don't have any experience with the exact mount you are writing about but I do own a Holland 1 piece (base) 20 MOA mount and I am very happy with it. It is solid and looks great. I sent the whole gun (Rem VLS .308) and scope (Leo 4.5x14x42 tactical) to Darryl and when he sent it back the scope was mounted perfectly and was dead on zero at 100 yards with the Federal high grade ammo using the SGK bullet. The scope and scope mount have not moved from their perch since that time and I would not hesitate to make that my mount of choice on any future LRH rifle I ever get. No lapping, no spacers or inserts, no shifting and no BS. It is simple and clean and that is the way I like it. Call or email him and see what he can do to help you out.

    Unless you have a long barrel (28" or longer) you might want to reconsider using a 168 for 1000 yard shooting.

    I'd start with a 175 or 180.

    Gentlemen,

    Greetings, thank you for the kind words on our Perfect Picatinny Rail Mount. It has 30 MOA left -right adjustment and comes machined from a near perfect Remington receiver with 20 MOA forward slope.

    It is as rugged and bullet proof as scope mounts can be. Being able to optically center the scopes reticle left/right up/down or with 20 MOA dialed in is a great asset to the long range shooter.

    Also, with manufacturing tolerances as they are, our base system can be machined to a PERFECT, I repeat, PERFECT stress free mount for YOUR individual receiver. No other mount system offers the versatility or ruggedness that we do.

    They are most affordable and any competent gunsmith can install one in a few minutes.

    Call for a free color brochure and say good-bye to scope mounting problems. 541-439-5155

    Sincerely,


    Darrell Holland

    My VS .308 has got a 26" barrel. I was told the 20 MOA base would get me to 1000 yds. with a 168 SMK in the factory Federal match load. Is this not correct? Is there not enough elevation in my MK 4 scope or is the problem the bullet is going subsonic?

    Dear Pat.


    Greetings, if you are shooting a handloaded 168 SMK at 2700 fps. you are still traveling 1206 fps at 1000 yds. the speed of sound is roughly 1120 fps at 3M elevation at 59 ° with 50% humidity. In other words you are on the edge given those parameters.

    If you shoot a 175 SMK which has a higher BC you will be traveling 1312 fps under the same environmental conditions. This gives you a better cushion of down range performance and keeping the bullet from going sub-sonic.

    Given the opportunity, always shoot the bullet with the highest BC for your intended application.

    With the above data you will require approx. 34.5 MOA with a 200 yd, zero for the 168 and 33 MOA for the 175 SMK. Your Leupold Mk 4 should have sufficient elevation to accomplish this.

    Best of luck to you...

    Sincerely,


    Darrell Holland
