3guns Posted July 6, 2020 Share Posted July 6, 2020 Does any have any starting load for .223 34 gr Nosler bullets? I got a good deal on the bullets and I'm looking to reload for bay type 3 gun stages. There is plenty of load info for prairiedog hunting with high velocity, but I'm trying the velocity bring it down a little. I primarily use H335 or TAC. Any info would be appreciated.

3guns Posted August 18, 2020 Author Share Posted August 18, 2020 So I loaded up the 34gr bullets with 21gr of H335. The bullets grouped within an inch at 50yds with almost zero recoil. I had to open up my adjustable gas block by half a turn so the rifle could cycle. My spare 3 gun rifle with a fixed adjustable gas block would not cycle the rifle. Overall I’m impressed with the lack of recoil of the round. I will definitely use this round in 3 gun matches for bay stages. Next step is to Chrono the round. Quote Link to post Share on other sites
TonytheTiger Posted August 18, 2020 Share Posted August 18, 2020 Interested to see the chrono numbers. Quote Link to post Share on other sites
Guy Neill Posted August 18, 2020 Share Posted August 18, 2020 Is there a required power factor? If so, that would be a factor when considering the load. USPSA Multigun rules, if I'm reading them right, states a 150 power factor for rifle. With a 34gr bullet, that needs something over 4400 fps. Quote Link to post Share on other sites
TonytheTiger Posted August 19, 2020 Share Posted August 19, 2020 I've never seen a match requiring power factor. I don't think there are enough USPSA Multigun matches for anyone to worry about their rules. Quote Link to post Share on other sites
3guns Posted August 19, 2020 Author Share Posted August 19, 2020 (edited) There is only one USPSA Multigun match that is popular. Multigun Nationals. I'll post up chrono data, next time I go out to the range. Edited August 19, 2020 by 3guns word left out Quote Link to post Share on other sites
wgj3 Posted August 19, 2020 Share Posted August 19, 2020 (edited) I did something very similar with light Speer bullets and 335 myself. I had a super-light BCG and light buffer/spring assembly in the gun and it ran great until the gun started getting a bit dirty. Like you said, almost no gun movement in "recoil". I think I ran mine over the Chrono with about the same charge and was just over 2000fps out of a 16" barrel... Edited August 19, 2020 by wgj3 Quote Link to post Share on other sites
