Course attendee for external ballistics course will require their own ammunition and rifle with a rifle scope that allows elevation to be dialled. We will check to ensure on the day that the scope is correctly married to the rifle and aligned to the centre of the bore for concentricity in long-range shooting.

The client is required to bring 100 rounds of calibre specific ammunition to their rifle they wish to use. This should be high quality ammunition either hand loaded from our advanced course and the client is wishing to learn how to achieve the external ballistics of their own load.

The course is held in any conditions the worst the weather is actually better for the client as they have conditions which will gain a greater learning curve so be prepared and dress appropriately.

Bring a packed lunch, sandwich etc as we will be out all day on the hill. This is a very fun day with so much to learn in a relaxed manner.
We spend time one on one to correctly advise you on your external ballistics for medium and long-range use this is course that has many great factors to aid the shooter gain further knowledge to make first round hits at distance.

We spend time with you going through your preferred load and working with you directly at an approved range out to 600 meters.

We advise on ballistics programs and talk you through the advantages and disadvantages on certain products, we want you to achieve confidence and understanding on what it takes to get your first round hit with your factory or home loaded ammunition.

The course is tailored around the client as each client has his/her own requirements such as long-range vermin control, deer management, long range shooting for competition such as PRS or F-Class Target for examples.

This course will give the client a great understanding with practical experience being advised during the whole process from fundamentals of marksmanship.

A real mixed day for myself with a creeping in of a basic error which looking back I should not allow these things to slip. Basic parallex slip at 1000mtrs. Causing impact shift old age and contact lenses don’t help. Fantastic company and always remember where you put your car keys is “key” lol 😂
22PRS Shoot report from Saturday 1st of June @ Sperrin sporting ranges.

What a super start to the beginning of summer with a beautiful day shooting the GBPRA 22PRS competition qualify at the Sperrin Sporting ranges 600mtr range.
With great weather and the wind that was as usual a little bit switching during the day which made some shots very tricky but fun. 
Great course of fire with many different props being used, the course director lain set up this competition with a greater amount of time on most stages allowing competitors to study their shots and placements so corrections could be made. It was a very smooth transition between each COF and a fun lunch stop with the weather being so kind to us. 
Overall it was a very tight match at the top with only one point splitting the top three shooters so congratulations to James Graham 71pts in 1st Place, 2nd Iain Baldwin 70pts and 3rd Jacob McIllwaine 70pts.
I would also like to mention one competitor Mr Darren Watson that has had some small amount of coaching from our team at Sperrin Sporting Ranges and got himself a 4th Place, so huge congratulation to Darren on his achievements this weekend.
