![]() ![]() In fact you could use 7.65mm pistol bullets which would even expand at subsonic velocities, but the muzzle velocity tends to be very erratic in 308 sized case. For terminal ballistics every bullet you can find would be fine and the trajectory is virtually the same (no gain from heavier bullets). Longer bullets (boat tail and hollow point) require faster twist to stabilize. I have a couple boxes of Horn 170 flat point (30/30) bullets. I have been looking for Trail Boss for a year and still haven't located a jug, so checking to see if anyone can share load data with other powders such as Unique, Lil Gun, and AA5744 for the 308 Win. In 1-10" barrel twist any flat base (no boat tail) bullets up to 200gr should be fine, if you have 1-12" the 150gr would be safe bet and 180gr may be on the edge. I've searched the archives and TB, TB, TB is always the answer. Beware though, jacketed bullets may be quite erratic regarding muzzle velocity. you could try and find some flat tip bullets like 150gr manufactured for 30-30 (flat tip required for tubular magazine). If this is not possible due to legislation etc. Round nose isn't optimal for terminal ballistics so I cut the tip flat (can be done with a metal file but I use mill). I've had good results with H&N ( H&N air gun pellets and bullets) plated bullets, very low muzzle velocity variation. From there on the drop's quite bad (1MRAD/7.5cm at 75m and 2.5MRAD/25cm at 100m are good rulees of thumb for any projectile at around 300m/s) and muzzle velocity variation can ruin the accuracy. With the 308 Winchester paired with the 150 Pro-Hunter and 168 SMK, I was able to make loads that had a muzzle velocity of approximately 60 of the full power charge (1,933 feet/second for the 150 and 1,856 feet/second for the 168), but it is possible to go even slower and lighter safely, with another powder, Trail Boss. Up to something like 50m, the muzzle velocity variation won't play a big role in accuracy. I've never used filler (Dacron or similar) since I'm concerned whether it would build up in moderator. I’m seeking alternative subsonic load data without Trail Boss. This is due to the low load density, even tipping the barrel up or down can have a drastic effect. A lot of casters use 32wc/hbwcs in the 30cals for small game/replacing the 22lrs. They do an excellent job in the 308s & 30-06s with 3.5gr to 5.0gr of bullseye. top right: nothing more than a 98gr hbwc for the 32cal target pistols. 309 flat point mold no gas check liquid Alex tumble lube wheel weight alloy water dropped wolf magnum large rifle primers bullseye 5.4-5. 308 once fired lake city brass cut to 2.006' after full length sizing Lee 170gr. ![]() Please be aware that muzzle velocity could vary quite much. Some of my favorite 30cal bullets that seem to hold their own at subsonic speeds. So I have been working up a load with bullseye powder to keep it under 1090fps for a subsonic. I have experience only in Vihtavuori powders, N310 and N320 are good, start from 9 grains and work your way down. ![]()
