![]() ![]() They might not feed as well being so short. This should approximate the same internal volume and get me closer on fps. I'm also going to measure the headspace inside the cartridge of the 220 SMK's and compare to the 220 RN's without making adjustments to the seating die. 5 grain of powder for my next loads of the RN's at this COAL. Since the RN's are so much shorter than the SMK's, there was a lot more head space inside the cartridge and it really showed in the velocities as both were loaded to the same respective powder charges. The RN's were seated initially without making any adjustments to the seating die but looked to be really short, so I pulled the first one and re-seated to 2.100 which, if I remember was an increase of 0.1"-ish. As they were loaded, they were pretty much a compressed load although I didn't measure. I'll have to keep working down the charge to get them subsonic. The SMK's were loaded to max magazine length. All rounds shot suppressed.Ģ20 gr Sierra Match King loaded to 2.260 COAL, Lake City Brass, Win small rifle primer, 11.3 and 11.5 grains H4198. Hi-Standard 300blk, 16" barrel, carbine length gas tube, AAC Cyclone-K. Both fed, cycled, grouped and BHO'd although the velocities were a surprise. 300 BLK, and you can load to 2400 fps.I just got back from the range (as in 20 minutes ago) with some chrony data using 220 SMK's and 220 RN's. I think for deer you would be better off getting some 110 gr Barnes Black Tips, which are made for. There are expanding bullets made for 300 BLK that work, but unless Barnes has come out with a new heavy bullet intended for subsonic speed, as a subsonic that thing will just zip thru soft tissue and make a. I am highly doubtful that the 200 gr Barnes will expand at all at the subsonic velocity you will get at that weight in. While i am asking if you have any 180 gr load data for LIL GUN that would be great also I have searched a little and can find all kinds of data for other weights. i know it would be a subsonic load, but the deer are small and they get really close.ĭoes anyone have an load data on a 200 gr pill. I have 10 Barnes TXP (i think that is the one) 200 gr bullets that i would like to load for some hunting reasons. The powder i want to use is LIL GUN, mainly bc i could find it. I am using some hornady 150 gr SST and some older spier points that i had laying around. Ok so i have finished my batch of brass and i am starting to work on my load data for the 300 BLK. Go to 300BLK forum for a cornucopia of knowledge on all things 300BLK. Subsonic rounds do not expand and are not the best choice for hunting. Fortunately Lil'gun is a very good supersonic powder. A good guideline is for best feeding, you want to set the ogive of the bullet so it is the same diameter as the 223 round where it hits the forward rib of the magazine.Īlso, for hunting, I would recommend scrounging up some 125 Pro-Hunters and using those instead. The recommended OAL for a 210 SMK is 2.120, and the Barnes is likely fairly long for weight so you may have to go a touch longer. If you absolutely have to give Lil'gun a try, a good starting load with a 200-210 gr bullet is from 8.2 to 8.7 gr, with an OAL dependent on specific bullet. Shooting with a suppressor increases backpressure and helps cycling alot too. If you are going to shoot alot of subs, I would also recommend enlarging the gas port to. I say this from experience, using an optimized system (standard CAR buffer, GI CAR spring, and well-lubed semi-auto carrier). You may also have luck with RL-7, or H4198, but those are more finicky. I have experimented with both carbine and pistol gas systems, and pretty much the only powder that reliably cycles a subsonic load in carbine gas is A1680. Lil'gun will work well for subsonic 200 gr, but almost certainly will NOT cycle your AR. ![]()
