Following on from last nights frantic post about reloading for todays trip out, I'm intact as is the rifle

We were on the Zeroing Range at Barry Buddon and it was blowing a gale but from the East so almost from targets (no butts) to FP. We always have a good turnout on 100yd ranges, most have scoped rifles and I don't get why people regularly shoot their target rifles at this range when they have not changed a thing since last time. I think they like to go home and tell folk how accurate their rifles areand how good they can shoot.

Anyway, 100yd range for me means either a 22 or iron sights. The 303 was running 40gns of N140 and jacketed bullets whose weight I couldn't determine as they were all over the place, but around 180gn. Sights set as low as they would go as min calibration is 200yds the rounds all made target and were a good 12 inches low with a decent 6" average group. I could hardly see the orange diamond from the FP. Wound the sight up to 200yds and the POI came up to about 6-7" below my POA whilst all rounds were falling about 1-2" to the right.

I can only assume that the low powder weight and resulting lower velocity means the rounds didn't have enough speed to group closer to the POA.

The rifle is very sweet to shoot with no issues over recoil etc.

A 1200 finish was enforced after the OTC decided that it was a little too windy for them. And these are suposed to be officer material, eeeesh!

A great day out, and lessons learnt and now more eager to get this Regulated No4 as accurate as possible.

Sounds like a good session mate

You adjust the vertical POI to POA with adjustable height fore sights to get zero on the rear sight at your desired distance.

Your bullet and trajectory may still not be on for all distances on the rear sight, a 200 or 300 yrd distance is good for setting a workable zero.

I've heard the same thing from a few people Mike and it's probably a mix of a few things.There's no butts so those that don't like going on the butt party so they have nothing to worry about,the short range helps to boost the ego and if i'm thinking of the right range theres plenty of round to shoot.

I find that 41g of N140 works well in my N04.

Nice one Mike, any pictures? Your 40g N140 may not be so bad, it depends on the maximum distance you are going to shoot it to, some where from 39.5 to 41grains should be a sweet spot so you should have to do very little fine tuning.

Regarding the sights, you can push your front blade out, measure it and then buy the correct size for your load/distance on eBlag, alternatively if it is just a standard blade you could always take a file with you and keep filing a bit off until it is good for target and then push it out back home, measure and order the correct size
