The benchmark ammo for my 30 cal R5 Matador is the 44 grain JSB. They list as 150 per tin but the 14 tins I have weighed and sorted contained 155-157 pellets.
The R5 shoots them 900fps. My ES 11.88 and SD was 3.87. 50 yard groups are about the size of a 35 cent piece. (not 25, but 35)
100 yard groups are 1.5 inch or less. I have not owned it long and still breaking it in. I expect it to really get better.
The H&N contained 205 pellets for two tins. Average speed was 894, ES 3.44, SD 1.41. I was excited when this printed out! I was using the 46.3 grain since I had 28 of those and the are listed as this weight,
I adjusted the scope a few clicks to allow for the weight differance and settled in.The first shot at 50 yards went dead center, I am real excited at this point. Fired the second shot and could only see one hole. Excitment builds as I search for a second hole, finding it way over right and high. What da????
8 more shots and only two shots were close to each other, could not believe it, the group measured almost 4 inches at 50 yards. I already had a clean target at 100 yards and took 5 shots at it. That group was 7 1/2 inches.
A friend of mine is coming when the weather gets better and bringing his 30 cal Crown. I will see what they do in it, I dont think they are suited for the R5
H&N 30 cal weight in grains for 200 pellets
odd ball-1 45.1
28 46.3
30 46.4
27 46.5
21 46.6
20 46.7
39 46.8
14 46.9
10 47
11 47.1
4 47.2
Total 205
Looks like these two tins ran to the high side on weight
I was told the R5 barrel has a 1/16 twist rate. May or may be a factor in performance in this application. I did not compare skirt size or pellet length but the head size is the same as the JSB,
Thanks for reading, mr007s,,,,,Life is GOOD
