: Ross Mk.III Sniper Clone : steveu February 04, 2022, 10:52:26 AM All,
Here is a link to the pictures of a Sniper Clone that I helped my good friend Deepfreeze with. https://www.milsurps.com/vbpicgallery.php?do=view&g=1306 It is a clone of the one that is on Forgotten Weapons with the Winchester A5 scope. It is sporting a Malcolm 3X scope with Steve Earle bases that HRH Combat Arms in Fort Worth mounted properly. It is about 98% finished. I need to clean up the hole for the front base in the handguard, repair a crack in the handguard with some epoxy and clean the barreled action and wax it. I free floated the barrel channel also. The action screws are torqued to 35ip. I did a ladder test with N140 and was getting a good group with 39 grains. I did not pursue that powder because I got to thinking about the length of the barrel and thought that N160 would be a better choice. After another ladder test, 44 grains of N160 came out on top. I only shot 4 rounds to conserve the .313" 185 FMJBT's that I have. The bullets and cases were weighed to 1 grain group. Cases are Remington's that are neck sized and expanded with a .310" ball. Primers were WW 8 1/2-120 LR. The barrel has some light pitting that can be seen with a bore scope, but is bright to the eye. The throat looks very good for a 100+ year old rifle. It should be a fine shooter in the next Vintage Sniper Match next month! Cheers, Steve : Re: Ross Mk.III Sniper Clone : admin February 07, 2022, 04:40:03 PM Very interesting. Looks like a fun rifle to show off and shoot. Nice that you are getting good accuracy with it. Thanks for posting.

Update on the clone. I finally got all the required bits to load some cast bullets for the rifle. Today I went to the range to test some loads. The bullet was from a Saeco #305 mould cast with isotope lead, sized to.312 and lubed with sagebrush lube. I used Alliant 2400, 5 shots of each charge from 16-18 grains in 1/2 grain increments. 17.5 seemed to be the best load, 5 shots at 100 yards that could be covered with a quarter. Next is testing at 200. I did not get any velocity data as my chronograph was not working properly. : Re: Ross Mk.III Sniper Clone : admin February 10, 2023, 02:37:51 PM Steve -
Thanks for the update. That is some fine accuracy. What weight is the bullet? : Re: Ross Mk.III Sniper Clone : steveu February 11, 2023, 10:17:53 AM With isotope lead they are 179.5 grains and measure .3125". I size them to .312". I am ver happy with the mould so far. I have updated the photos in the link that have the target picture.
