  1. March Genesis

    Chris, 0.05 mrad clicks should not be an issue, I have them on my March 5-40x56 fx scopes. I guess for an ELR scope they should be standard. Objective size is always going to be a compromise on an external adjustment scope - bigger objective = less elevation adjustment before the objective bell contacts the barrel or forend tube. March are making two heights for the actual mount - the one pictured and a higher one for tube guns. Cheek piece / comfort height is then an issue. Personally having had an 80mm objective on the sn9 anything more than 65mm would awkward for me .
  2. The 'Tactical' K31

    Strongly agree with that statement Vince, second rifle down in the pic is a trg22 - same barrel, action, mag, trigger. Now gets a heavy assed cnc stock. Thing is I was at a very sandy and wet range for two days last week , there were two Tikka Tacs and a Tikka varmint in a krg stock. The two Tikka tac’s both had mag feeding issues and the varmint ignition issues - all due to wet sand getting everywhere. The AIAXMC never missed a beat. Moral - cool stocks are nice eye candy.

    Nope, my ELR days are gone with the AW50. The 338 really never gets used beyond 1km and usually only to 800m these days. The Genesis would not look out of place on the AXMC but it is a question if 60x offers me anything over 40x magnification with regards to seeing shots on target - it’s still a 56mm objective. It’s about resolution rather than magnification. There is time to see how it will be refined and I will wait for the milrad version anyway.

    Scotch, handled it today at the IWA. Same sort of principle as uso sn9 - which I’ve had a couple of for ELR, however the March gimbal system should be an improvement over the uso ball joint system.
  5. The Mighty AK Continues as the AK-12 and 15

    One of my personal firearms is an AK Alfa. Ak made in Israel (left with standard AK on right). Superior quality and embargo friendly. This one is in 223 Rem but can be had in 7.62x39. The best of breed an AK 107 (opposed piston) is still made from unobtanium here.
  6. A different shooter

    Dave that is lovely. Having my own woodland here I also dabble a bit in 3D shooting and encourage the kids to do also. Pic is my bow, Mathews Chill, copper John / Swarovski optic etc.
  7. Scope Calibration

    Gluv, it is worth checking for poi changes through the magnification range if using a 2fp scope. A different method here - when I was playing at ELRish ranges, now some 8 years ago this is what I did to get my AW50 out to 1500m with 700 grain lathe turned solids. Scope was a 12-42x56 NXS with I think 40 moa base on it. First I used my colimator, Checking tracking, click values and poi changes throughout the mag range. Then I went to an optics manufacturer (Meopta) and put it on one of their colimators - a bit more Gucci but same principle. So first step the scope is tracking without being subject to recoil. Step two at a 300m range, with full side baffles (Holesov) zero and shoot some groups. Doing my part 5 shots would hold 5 cm. I also know on that range I am regularly 2cm to the right - spin drift. After zeroing put up 10 regular sized clays - should get 100% first shot. Scope maintains poi with recoil. Now multiply target size by 5 and place at 1500m (different range) but even after sighted in 50% hit rate was very good for me. The small variables just become more important - ES and effect on decent angle, precession and of course wind drift, but plotting shots showed as many misses to vertical error as horizontal - wind drift. To try and put these things into a ballistic calculator you end up chasing a ghost. But I was confident it was not scope error. Granted some things have changed - Lab radar being much more reliable than my chrony and if you use Lapua bullets the 6 dof program is good. I will ask them at the IWA how far they tested out to with Doppler radar and how much is derived data.
  8. Scope Calibration

    VarmLR, with reference to that article. It is now several years old and some of the scopes have evolved. With reference to the March scope on that test I remember asking March Optics- they told me that the scope sent for that test was a test model and for whatever reason I forget had a different system of milradian in it - there being 6000or 6300 or 6400 degrees in a circle, depends which criteria you use, as a miltadian is an angular not linear measurement.
  9. Scope Calibration

    Gluv, an easy and fairly cheap solution Is to buy an optical colimator. In essence it looks like grid lines in front of the reticule, you can vary the size of the grid with your scope magnification. It allows you to accurately “see” what the turret adjustments are doing and accurately measure them. In an extreme case I have seen vertical adjustment also give a degree of horizontal displacement ( I could see the crosshairs “jump” when manipulating the turrets). It is also required to have the vertical crosshair perfectly vertical to avoid horizontal displacement which will affect vertical displacement also - vector. The advantages of using a colimator are that you see what you tracking is doing - at home and it isolates just that and it is easy to check the full range of vertical and horizontal tracking adjustment Things that it does not do -!show the effects of recoil on scope tracking. With other forms of establishing how your scope is tracking you get into many external factors including - rifle cant, load variations and to a lesser extent mechanical tolerance variations within the scope due to things like temperature change.
  10. Very nice Andy. I can tell you that your work is very much sort after by Czech and Slovak shooters.
  11. Drivinfish, please come for a brew, biscuits and chat. We will have some Czech soft beverages at the bss but I will be taking something a bit stronger to the IWA.

  13. Edi, we are exhibiting there as Czech Tactical Pursuits, stand D6 ( rifle section, somewhere near Accuracy International I believe). Please stop by for a coffee and chat. I will also be going to the IWA for a look around - will bring a bottle of Czech special for you - I much appreciated your hospitality last year. Anyone else on the forum (other than internet angries) please stop by for a chat and a brew - might even be some fig biscuits if I haven’t scoffed them all.
  14. If you want to talk about cheating start a new topic. Post not related to bench v prone will be deleted.

    MO, what was the issue with the Sordins? We give our clients basic Peltors for range use and for pistol/ carbine courses as instructors we use the same Peltor mil muffs because they are electronic and can crank up the volume to here what’s going on behind the firing point. In my rifle kit I have Sordins, the wiring or rather the rubber wire sheathing seems more durable on the Sordins, plus they fit my head a bit better and do not contact the cheek piece which is important for comfort and keeping the pads sealed against your head ( little use otherwise). Everyone’s face shape will be different so what works for one may well not work for another. The biggest difference that I notice between muffs is weight. If they are electronic or not. Doing a weeks carbine course wearing electronic muffs all day it Is nice to change out to bog standard light muffs. The electronic gubbins is just a necessary evil for us.
