Sterling White Posted January 6, 2010 Share Posted January 6, 2010 I ran a search query on Ramshot Tac and it looks like there are some folks testing it however not a lot of feedback. Specifically, am interested in learning more about loads for the 223 (5.56), 6.5 Grendel, and 308. Will start some of my own test soon but nothing to report right now. Any suggestions for a 62gn and 69gn? Link to comment Share on other sites More sharing options...
hockeyfighter25 Posted January 6, 2010 Share Posted January 6, 2010 I haven't had a chance to try them out yet, but I loaded up some test rounds of .223, 69 gr nosler comp, and various weights of tac. From what I can tell from a few threads on here, tac seems to be popular with heavier bullets 69 gr and up in .223. It is talked about a little bit here. http://www.brianenos.com/forums/index.php?...&hl=tac+223 Link to comment Share on other sites More sharing options...
SA Friday Posted January 6, 2010 Share Posted January 6, 2010 I've used Ramshot Tac with moa to sub-moa results with 55gr to 75gr bullets in 223. Test each load at 100 and 200 yds. I found a lot of rounds don't look very good at 100 yds, i.e. 1.25-1.5" groups, and then shoot the same group size at 200 yds and equivalent moa past 200.

Jaxshooter Posted January 7, 2010 Share Posted January 7, 2010 I am one of the people that was working on loads with TAC for .223 and .308. I have just not had time to sit down and work on them. I did get presses set up and brass fully processed to start loading. I will try to get something done in the next few weeks. It is really cold here in Florida right now the high today was 45 degrees with a 10-15 mph wind. Link to comment Share on other sites More sharing options...
Jman Posted January 7, 2010 Share Posted January 7, 2010 It is really cold here in Florida right now the high today was 45 degrees with a 10-15 mph wind. That's crazy cold for F.L.A., ridicules. Thread drift.....OFF Link to comment Share on other sites More sharing options...
Sterling White Posted January 7, 2010 Author Share Posted January 7, 2010 Thanks Hockey and guys...I did see that thread and the title of it specified TAC and 55gr Ballistic Tips in .223. I am hoping to capture more information however some good information there. My plans are to start with 62gn and 69gn bullets. And progress to testing other loads for the two calibers soon as well.

laportecharlie Posted January 7, 2010 Share Posted January 7, 2010 We have been using TAC in our 223 Rem Prairie Dog loads for the last year or so. I think we are on our firth or sixth eight pounder. Accurate, burns clean and cheap. 25 grs and a MidSouth 55 gr Varmint Nightmare and you are good to go. Charlie Link to comment Share on other sites More sharing options...
technetium-99m Posted January 8, 2010 Share Posted January 8, 2010 My first results with it are promising, I was using Hornady 68gr bullets and 23.6gr of TAC. I've loaded some up with 75 and 77gr bullets but have not shot them yet. Link to comment Share on other sites More sharing options...
Hotshoer Posted January 9, 2010 Share Posted January 9, 2010 (edited) Sterling, I'm having great results with 23.7g of Tac over 69g Sierra Match Kings. Hoping to work something up for the 55g MG's. Too cold to do anything yet in Old Va., will keep ya posted. Your buddy, Steve. Edited January 9, 2010 by Hotshoer Link to comment Share on other sites More sharing options...
BigDave Posted January 9, 2010 Share Posted January 9, 2010 Isn't about 25.5 gr of Tac under a 68 gr BTHP a copy of the Black Hills commercial load? Link to comment Share on other sites More sharing options...
fastshooter03 Posted January 10, 2010 Share Posted January 10, 2010 I think it was 44.0 grains TAC with a 155 NOs CC that got me a 5/8" 5-shot group @200 yds with my DPMS 24" 308. Nick Link to comment Share on other sites More sharing options...

mpeltier Posted January 10, 2010 Share Posted January 10, 2010 Sterling I have been experimanting with Tac for about a year now and following is some load info I have compiled. The velocities are from my current 1/8 twist 18" 3 land poly rifled bbl. You should crono your load development in your bbl to be sure of your velocities. Factory (from production lots I pulled and weighed) BH 68gr Heavy match = 24gr Tac = 2715 BH 75gr BTHP match= 23.8gr Tac = 2700 My Reloads 75gr Hornady = 23.5gr Tac = 2664 75gr Hornady = 24.5gr Tac = ? not chronod yet, but no over presure signs and great accuracy from my bbl. 55gr MG FMJ = 24.2gr Tac = 2911 I load to an OAL of 2.243 I hope this info helps you out. Remember to work up slowly and watch for sighns of overpressure Link to comment Share on other sites More sharing options...
kevinj308 Posted January 10, 2010 Share Posted January 10, 2010 I tried it in .308. 24" barrel, 1 in 10 twist, all loads at 2.8 OAL, 175gr SMK. 38gr=2372 39gr=2420 40gr=2494 41gr=2570 Just started playing with it, still have a lot of work to do. But honestly it hasn't performed very well so far. Kevin Link to comment Share on other sites More sharing options...
Sterling White Posted January 15, 2010 Author Share Posted January 15, 2010 Thanks Mark and all - Good advice. Started the break in process with the grendel yesterday. Loaded 29.5gn behind a 107scenar. According to personal comm. with a tech at Western I should use 32.2gn as a max. and not go higher. The journey begins.

PHolsted Posted April 8, 2010 Share Posted April 8, 2010 I hope this info helps you out. Remember to work up slowly and watch for sighns of overpressure I have been loading pistol for a long time but have just started loading for rifle. I am working up a load for 69gn Sierra.. What are the key signs of overpressure I need to look for. Thanks Link to comment Share on other sites More sharing options...

What are the key signs of overpressure I need to look for. Thanks Look at the primer for flow, or, cratering. If you are running a bolt action, the bolt won't open as easy.

freakshow10mm Posted May 10, 2010 Share Posted May 10, 2010 TAC is a great powder. Just as fast as Varget but burns cleaner and meters better, being a ball powder. I loaded my .223 with TAC when I had a .223. Link to comment Share on other sites More sharing options...
boomfab Posted May 24, 2010 Share Posted May 24, 2010 I load 25.4gr of TAC with 69 SMKs, it's extremely accurate. Link to comment Share on other sites More sharing options...
slavic09 Posted June 27, 2010 Share Posted June 27, 2010 My rifle seems to like 23.2 gr of TAC under 69 gr. SMKs. It shoots under a minute consistently. Link to comment Share on other sites More sharing options...
CraigS. Posted July 2, 2010 Share Posted July 2, 2010 My rifle seems to like 23.2 gr of TAC under 69 gr. SMKs. It shoots under a minute consistently. Just wondering what velocity are your rounds going? Iam guessing <2600 Link to comment Share on other sites More sharing options...
KentG Posted December 29, 2010 Share Posted December 29, 2010 (edited) Im getting ready to load Tac under 69 gr SMKs in the next few weeks. The Ramshot homepage shows a load of 21.6 to 24.0 gr. From the info I have seen here and elsewhere Im going to start a few at 23.4 ish and chrono. Bad part is since its winter I hope I can get a day over 50 to chrono and check poi @100 to start.

foilhat Posted December 29, 2010 Share Posted December 29, 2010 I've had best results,in my rifle, with 23.8g TAC 68g BTHP. I also use Ramshot X-terminator for 55g bullets. 1/9 twist 16 inch. Link to comment Share on other sites More sharing options...
R-Bros_JLR Posted December 29, 2010 Share Posted December 29, 2010 I use 23.5g of TAC behind a 77g SMK out of my 20" WOA precision gun and get ~2750. I've ran up to around 24.5 but backed it off since it was pushing the limits in HOT weather. Link to comment Share on other sites More sharing options...
Ken Kwiat Posted January 1, 2011 Share Posted January 1, 2011 I've been using Tac with 77 gr. SMKs for a couple of years now. Very happy with the results. Sub-MOA out to 425 yds. observed (.5 MOA at 100 yds), 18" MSTN, WSR primers. I'm running 23.9-24.0 gr. -- last chrono was 2670 fps (SD in low teens, DensAlt: 8630'). And, it meters well enough to use with the standard Dillon powder measures (compared to Varget, for example). Note that I'm at altitude as I believe I'm on the high end of what Ramshot publishes. Pressure signs just beginning. I was running a bit hotter with flattened primers so I dialed back. Link to comment Share on other sites More sharing options...
