Talked with Seekins, the barrel is a 1:11.25 and they recommend using 168gr match grade ammo to get the best results. It should be here next week along with all the equipment to start building rounds. Going to start with Hornady 168 grain HPBT match bullets, Federal LR primers and Ramshot Tac powder. Looking at some match grade ammo they are pushing about 2680 fps so I'm going to start around that mark. Any questions or concerns please let me know, I really despise how many choices and combinations there are in rifle loading[emoji35] Sent from my iPad using Tapatalk

I am looking into purchasing the Seekins SP10 308 18" rifle for competition use. Looking to use it just a few times a year. Shot range will be from bay type shooting out to 800 yards. I currently reload all my own ammunition for other calibers but not set up for the 308 yet. I am looking to purchase about a 1000 rounds for break in, practice and competition. I do not know the twist rate of the match grade barrel at this time as they don't advertise it. So i need a few things from this group before I pick it up. 1. Ammo recommendations for brand and bullet weight for general accuracy, economy and able to hold 1-2 MOA groups. Longest shot known now is 650 yards. Note: I am not sponsored and I am not rich! 2. Knowledge and/or experience with the mentioned rifle 3. Best way to break in the barrel if needed or just heat it up the old fashion way? I appreciate the responses as this is on a short time window of opportunity.

It was the best match I have competed to date, definitely going to push some of the design on my local club, they will probably bitch about it though haha. Sorry to hear that on your rifle, all my equipment ran great for once, I was the issue here. These old knees just about had enough by the end though and definitely coming back next year for more abuse Sent from my iPhone using Tapatalk

Made it through the match, all the load building paid off and I hit the 620 yard shot after about 15 rounds. 18 x 24 steel on a MGM T-post hanging by a piece of 4" fire hose. Problem was a 25mph 2:30 wind and a twisting target. At least I hit it, that's all that matters right? What really had me thinking was the 180 yard slug shot and the 130 yard pistol shots! All hits but it sure got inside my head before doing them. Sent from my iPhone using Tapatalk

I actually spun the slug spinner with 4 hits out of 5 shots but couldn't get the hits or timing down on the rifle Spinner. Thought it turned over, RO said no I moved on Sent from my iPhone using Tapatalk

Thanks, I appreciate that! I know it can get better as I improve my technique. I was very satisfied with the readouts of the load and I have all of the input from here to thank for that, you guys have taught/given me a ton of good advice. Thank you! Sent from my iPhone using Tapatalk

Received some sierra 77gr and loaded up a few...they shoot better than the hornady and I have read that somewhere before. I am sold! Loaded 23.6 gr of TAC at 2.20" here is the data for the 5 shots. Still not a sniper yet but it is big progress! Mean Velocity - 2627 fps SD - 9.7 Spread - 27fps .856" 5 shot group at 100 yards

shoot 9mm with a M&P shoot 40 with my STI Shoot 45acp with my S&W 1911 Shoot 223 with M&P ar

10k and counting without hardly any issues. Found bad seating on a few that didn't go off the first time but did when I ran them through again. I like them and wish I could find some more to pick up

It does do both tasks and quite well. Just have to screw it down a bit more to reach the next landing

that could be true as I was trying the SSP top bifocal lens out. first time to use them and the first 2 targets were doubled. That had slipped my mind until now. By the end of the match they were second nature, pretty cool glasses and work fairly well once you get used to them

Thanks, that means a lot from a 60+ year experienced shooter! I noticed a couple of bobbles in the foot work that caused me to loose focus on the targets for a bit. I finished 5th on this stage but first was a full 7 seconds faster and on a different squad so no comparison video to look at. He is always faster than everyone but doesn't look like at the time, that is what I need to tap into!

Had a local match this last weekend, finished 7th out of 25, looking to shave a few more seconds. anyone see something to comment on?

I will probably just use them up as a mid range on the spinners or plate racks, bought 500 and hate to see them go to waste.

Not off topic, I have not seen or heard of a 3gun match to go that far but some around south Texas do go to 300 or 400. This originally started in an effort to build a round in preparation for the Seekins Precision Hard as Hell match which advertised out to 620 yards for rifle. It has been posted here a ways back that the longest was around 450 and with a stage gun. It has wandered back and forth but I'm using all the information I can get!

I am one of those mere mortals...I have been looking for a good deal on some Sierra's but nothing has come up yet. What list are you referring to? Only reason I picked some up was because of this thread and the good things said about it. I tried Varget, did not like the it metered at all, I guess it wouldn't be that big of a deal if I went out and bought a Chargemaster or something like that. I am going to shoot out the components I have and try some others down the road a bit, but for now, I have about 14lbs of powder to burn up

Well, I think I might be about 90% and have decided on a load to finalize. COAL or thereabout 2.200" BTO of 1.7935" using Hornady 75gr BTHP with 23.4gr of TAC traveling at 2627fps. Which puts my Razor BDC hashes under 600 yards so I will tweak this a little more to get the FPS up, SD lower and the ES smaller. Looks like I will need to be right at 2700fps to make the BDC cover the distance. Last trip to the range I shot out at both 100 and 200 yards and came up with several consistent 1 MOA groups with the BCA barrel and tried the BPM barrel as well. It did shoot a little better so it might be what I stick with, we will see!

The scope I have now is the Vortex Viper PST 6-24x50, I have only shot with it once and I don't think it is the scope as I can actually see the grid lines now. Got a few things to try out such as holding the follow through on the trigger, put 6 rounds in the mag to shoot 5 rounds, the last batch of bullets made using the Base To Ogive measurement instead of COAL. Then we will see what to do next. I believe these last rounds are built to the best of my ability.

Well that might be one way, but not ready to go that route yet. Feel like I have made a lot of ground on my reloading knowledge and still need to run the last couple of small batches I have made up. I do have another upper to try from Barnes Precision Machine that I won from one of our local matches so if all fails here I will be going back to a 16" barrel.

It's hard to catch anyone right now, working everyday and rushed in the evening (only an hour of sunlight left) to try the next batch. Got this coming Sunday off so will see if I can latch onto someone for a few shots. I will have to try some out, looks like most places are out of stock. Got a vendor you buy them from?

you are right, never thought about that. Thanks for the tip

Received the Hornady Bullet Comparator today, measured the last 15 rounds I made of 75 grain BTHP match to test and was a little shocked at the findings. I see why now you don't measure and rely on on COAL and expect everything to be the same. As far as COAL i had a difference from shortest to longest of .0005", could be less or a little more as I am using a digital caliper. Now using the comparator on the same 15 rounds I had a overall difference of .0100". I measured 10 of the 75 grain BTHP match bullets and they were exactly the same from bottom to ogive, the 68 grain BTHP had a difference of .002". I first thought I would pull these and start over but I am going to build 10 more measuring off the ogive to see the difference in how they shoot. Its fun figuring this out with all you guys that offer help.Thanks

Got the pants and knee pads so I will be covered there, I was thinking about gloves but haven't picked any up yet...suggestions?

Thanks for the foresight, I will continue because it is intriguing and I hate and can't leave a problem unsolved. Any insight to what the stage gun was? Type of scope?. Can't wait to use the breach gun and throw the flash bang.

Thanks dauntedfuture for the humor, very much appreciated and it did make me laugh.
