help No4 MK1 shooting low at 100Y

Thanks,Well.. it would be hard to find ammo that was made for this weapon, as i gather iam not the only one had this issue. What this really means is that the old boys were shooting some real hot loads back in the day!

To find a decent supply of reliable Mk 7 ball, yes. Shooting a range session with Mk 7 ball would hopefully give a good baseline figure for the sight settings on your gun.

However, if you just want to use the rifle on a regular basis with readily available ammo, then shoot your range session with that and collect the fall-of-shot data for posting here.
Suggested sight adjustments could then be made for you.

(Sorry Peter, most unlike an Aussie to be so verbose - well, when sober anyway...)

Now its getting interesting, What type of recipes can I use for 303 British. What type of bullet you suggest 174 FMG BT or 168 or 150. I don't have the reloading book with me right now.

Do you mind me asking how you shot that group? Did you fire a shot then check the bullet placement with a spotting scope, then fire the next etc?

I ask because the holes are walking round in a circle and look like each shot was aimed at the last hole, and not at the centre (or same place on the target each time) of the target.

Hi David , Thanks for the comment, but I am ways to go for calling shots like that maybe never. Interesting point, i don't know if even Sgt York could call shots like that with scope and correct ammo. maybe not! Hopefully sooner than latter! In reply to your question, i just numbered the impacts to ID the shots due to having more than one caliber being used. Back to the original topic of sighting at 100Y. To rank one to say five,you may add to that if need be (1) being the sharpshooter, say with iron sights. What would be acceptable grouping at one MOA @ 100Y is one inch. I don't know if that is even possible, but for the joy and participation of the folks in this thread and so going down the field.

I use a Rifle No8 (.22). Rear sight for 100yds and a change the front sight height.
The Group was shot at 100yds with a No1 Mk3 * 1917 Fultons Regulated Bsa Barrel. 174g PPU heads 38.4g N140
