Re: SemiAuto, 6 groups, 5shot each, 30 round SHOOTOUT!
Nice job USMAGator. You improved your #'s on both average and best single. Very nice.
If you're asking for advice I think the biggest thing that could help you out would be sand bag support on the rear (I would start here first).... I know most people use a sand bag under the buttstock, but I actually use mine under my grip (yes, I know it is strange).. Just happens to work better for me and my funky sand bag. I think I might get a "wedge' style rear sand bag for my buttstock. As for my weld, I usually re-set after each group. I only load up 5 rounds in the mag and will let the bolt stay back after the 5shots / 1group in order to let my barrel to cool down / allow air flow through the barrel for about 5min... I will actually touch the barrel with my finger and if it is too hot, then I don't shoot. I personally only touch the grip on the rifle when shooting... nothing else other than shoulder to buttstock... i do not hold onto the front forearm,,,, just the grip and allow the rifle to flow like water into my shoulder.... I try to let the bipod / rear bag do most of the work so I'm taking my heartbeat out of the equation. If you grind the buttstock into your shoulder too hard and hold onto the grip too hard you will increase your heartbeat thru the rifle / scope. Like I said before, only thing touching the rifle is my hand on the grip and my shoulder on the buttstock.... I do not have the buttstock ground into my shoulder,,, just somewhat firm. Last and final note,,,, SCOPE SHADOW IS YOUR FRIEND AND ENEMY. I try to keep my optics as clear as possible when taking the shot,,, I take no shot what so ever if I see any scope shadow. By doing so, I keep my eye alignment dead center of the optics. I also like to use 3/4" round dots @ 100yards and will crank up my optics to max 16x with sidefocus to obvious 100yards,,,,, and will place that small 3/4" target like a mildot on my crosshairs. Try to center as best as possible. Not saying this is perfect, but this is what I do.
<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: USMAGator</div><div class="ubbcode-body">So I finally made it back out today and gave this another try with the OBR. The biggest thing I noticed was that towards the end of each string I felt that I was driving the gun with the grip....I couldn't stay comfortable behind the rifle and it definitely showed with some of the "fliers". I've heard that it's good to try to maintain your cheek-weld throughout an entire string for best consistency, but I feel like as the string goes on I'm having to wrestle with the rifle more and more to keep my weld and stay on target. What do y'all do? I think next time I'm going to try coming off the rifle between each shot and try to get back to the same position each time so that I'm not forcing it by the end of each string.
Rifle was 18" OBR 7.62, shot from a bipod, no rear support, off the bench. Ammo was 168gr SMKs over 43.0gr BL-C(2), loaded to 2.800in. Scope was adjusted after the first target.
The one BAD flyer was the last shot of the day on the bottom right target.....I knew it as soon as the trigger broke, it just didn't feel right but I thought I could hold it together.
Measurements were done edge to edge and bullet diameter was subtracted (-.308").
1.330" + 1.097" + 0.663" + 1.141" + 0.683" + 1.918" = 6.832"/6 = 1.138" AVG
Best: 0.971" - .308" = 0.663"
For the folks that have done the SH online training for driving big gas guns, would you recommend it to others? I thought I could master this thing on my own, but it's very different from shooting bolt action and I want to shoot to my potential. More practice, or is training in order? </div></div>
